Question 1

Carlos writes about a how-to text called “Build a Simple Bird Feeder.” He wrote, “The author’s point is pinecones make easy feeders. The reason is birds can grip them. The evidence is ‘spread peanut butter in the cracks’ and ‘roll it in seeds’ (Steps 2–3).” Does Carlos explain reasons and evidence correctly?

  1. No, because steps are not evidence and cannot support a point.
  2. Yes, because he names a point, gives a reason, and cites step details as evidence. (correct answer)
  3. No, because he should explain the characters’ feelings during the steps.
  4. Yes, because he only needs to tell the main idea without any text references.

Explanation: This question tests 4th grade writing skills: applying grade 4 reading standards to informational texts, specifically explaining how an author uses reasons and evidence to support particular points in a text (CCSS.W.4.9.b). When students write about informational texts (articles, textbooks, nonfiction), they analyze HOW the author constructs the text, not just WHAT the text says. The standard specifically mentions explaining "how an author uses reasons and evidence to support particular points." This means: identifying the author's main point or claim (what author wants reader to understand), explaining the reasons the author gives (WHY the point is true, the author's explanations), and describing the evidence the author uses (specific facts, statistics, examples, expert opinions, data that prove the reasons). Carlos reads a how-to text called "Build a Simple Bird Feeder." Carlos analyzes how the author uses reasons and evidence. Carlos's analysis identifies the point that pinecones make easy feeders, explains the reason that birds can grip them, cites evidence such as the specific instructions "spread peanut butter in the cracks" and "roll it in seeds" from Steps 2-3, and explains the connection. For example, Carlos quotes "spread peanut butter in the cracks" and references Steps 2-3 where author states these instructions. The analysis includes specific textual support. Choice B is correct because Carlos names a point, gives a reason, and cites step details as evidence. For example, Carlos identifies the specific point (pinecones make easy feeders), explains the specific reason (birds can grip them), and cites specific evidence from the text (the instructions about peanut butter and seeds from Steps 2-3). This shows Carlos is analyzing HOW the author constructs the argument, not just summarizing what the text says. The analysis identifies specific instructions as evidence that support the author's point. Choice A is incorrect because this claims steps are not evidence when specific instructions and details from how-to texts can serve as evidence supporting the author's point about why a method works. Students sometimes don't realize that in informational texts, various types of specific details—including instructions, procedures, or steps—can function as evidence. Analyzing how authors use reasons and evidence helps you become a critical reader—you learn to evaluate whether arguments are well-supported. To help students apply reading standards to informational texts with focus on reasons and evidence: Teach types of evidence explicitly—Facts (can be verified), Statistics/Data (numbers, percentages), Examples (specific instances), Expert opinions (what authorities say), Descriptions (detailed explanations), Instructions/Steps (in how-to texts); emphasize: In how-to texts, the author's point might be about why a method works, with reasons explaining the benefits and evidence including specific steps or instructions that demonstrate the method; model with think-aloud: "I'm reading this how-to text about bird feeders. The author's point is: Pinecones make easy feeders. Now I'll find the reasons the author gives: Reason: Birds can grip them. What evidence does author give? The author provides specific instructions like 'spread peanut butter in the cracks.' That's evidence showing how the method works."; require text references: "You must cite specific evidence from text: quote it, reference the step number, or describe the specific instruction." Watch for: students who think only certain text types have evidence; students who don't recognize that instructions or procedures can serve as evidence in how-to texts; students who don't understand that informational texts include various genres (articles, how-to texts, textbooks) all requiring analysis of reasons and evidence.

Question 2

Marcus compares two analyses of a space article about Mars. Analysis 1: “The author thinks Mars could have had water because scientists found dry riverbeds and ‘minerals that form in water’ (para. 4).” Analysis 2: “Mars is interesting and far away. The article tells many cool facts.” Which analysis better explains the author’s reasons and evidence?

  1. Analysis 2, because it tells the topic and uses exciting words.
  2. Analysis 1, because it gives a reason and cites specific evidence from paragraph 4. (correct answer)
  3. Analysis 2, because it is shorter and easier to read.
  4. Both, because neither needs facts or quotes to count as evidence.

Explanation: This question tests 4th grade writing skills: applying grade 4 reading standards to informational texts, specifically explaining how an author uses reasons and evidence to support particular points in a text (CCSS.W.4.9.b). When students write about informational texts (articles, textbooks, nonfiction), they analyze HOW the author constructs the text, not just WHAT the text says. The standard specifically mentions explaining "how an author uses reasons and evidence to support particular points." This means: identifying the author's main point or claim (what author wants reader to understand), explaining the reasons the author gives (WHY the point is true, the author's explanations), and describing the evidence the author uses (specific facts, statistics, examples, expert opinions, data that prove the reasons). Marcus compares two analyses of a space article about Mars. Analysis 1 identifies the point that Mars could have had water, explains the reason that scientists found dry riverbeds, cites evidence such as the specific quote "minerals that form in water" from paragraph 4, and explains the connection. Analysis 2 provides vague statements without specific text references. For example, Analysis 1 quotes "minerals that form in water" and references paragraph 4 where author states this fact. Analysis 1 includes specific textual support while Analysis 2 lacks specific reasons and evidence from text. Choice B is correct because Analysis 1 gives a reason and cites specific evidence from paragraph 4. For example, Analysis 1 identifies the specific reason (scientists found dry riverbeds) and cites the specific evidence "minerals that form in water" from paragraph 4, which are specific pieces of evidence from the informational text. This shows Analysis 1 is analyzing HOW the author constructs the argument, not just summarizing what the text says. Analysis 1 uses textual evidence including specific quotes from the text to support the analysis. Choice A is incorrect because this claims Analysis 2 is better when it doesn't recognize that Analysis 2 makes vague statements ("many cool facts") without citing what evidence, while strong analysis names the actual evidence from text. Students sometimes accept vague statement ("author gives reasons") as identifying specific reasons when strong analysis names the actual reasons from text. Analyzing how authors use reasons and evidence helps you become a critical reader—you learn to evaluate whether arguments are well-supported. To help students apply reading standards to informational texts with focus on reasons and evidence: Distinguish analysis from summary—summary: "The article is about Mars. It tells many cool facts." (WHAT text says); analysis: "The author argues Mars could have had water (point). The author gives the reason that scientists found dry riverbeds (reason). The author provides evidence: the fact about 'minerals that form in water' (specific evidence from text)." (HOW author uses reasons and evidence); practice with texts: read informational article together, identify: What is author's main point? What reasons does author give for this point? What specific evidence (facts, data, examples) does author provide?; teach types of evidence explicitly—Facts (can be verified), Statistics/Data (numbers, percentages), Examples (specific instances), Expert opinions (what authorities say), Descriptions (detailed explanations); require text references: "You must cite specific evidence from text: quote it, reference the page, or describe the specific fact/data/example." Watch for: students who confuse narrative analysis with informational analysis; students who don't understand difference between reason (explanation of why) and evidence (proof with facts/data); students who don't use text references (quotes, page numbers, specific facts); students who list evidence without explaining how it supports author's point.

Question 3

Carlos compares two analyses of an article on wolves. Analysis 1 says, “Wolves are cool and I like them.” Analysis 2 says, “The author claims wolves help ecosystems. A reason is they control deer numbers. In paragraph 5, the author reports, ‘After wolves returned, young trees grew back because fewer deer ate them.’” Which analysis better explains reasons and evidence?

  1. Analysis 1, because it shares a personal opinion that clearly shows how the writer feels about wolves.
  2. Analysis 2, because it names a reason and cites a specific reported fact from the article. (correct answer)
  3. Analysis 1, because it uses short, friendly words that make the writer's point easy to understand quickly.
  4. Analysis 2, because it lists every fact from the article in the exact order the author wrote them.

Explanation: The best answer is the one saying Analysis 2 names a reason and cites a specific reported fact. Analysis 2 identifies the author's claim (wolves help ecosystems), gives the reason (they control deer numbers), and quotes evidence from paragraph 5 about young trees growing back. That is exactly what explaining reasons and evidence means. The choice praising Analysis 1 for sharing a personal opinion is wrong because saying you like wolves is a feeling, not an explanation of the author's reasons or evidence. The choice praising Analysis 1 for short, friendly words is wrong because being easy to read does not mean an analysis explains reasons and evidence at all. The choice saying Analysis 2 lists every fact in exact order is wrong because Analysis 2 does not retell everything; it picks one reason and one piece of evidence and explains how they support the point. Good analysis of an informational text points to the author's claim, reason, and evidence—not just to opinions, easy words, or a full retelling.

Question 4

Chen is writing about an article on desert animals. He wrote, “The author’s point is camels survive without much water. The reason is they store energy in fat. The author supports it with the fact ‘a camel can go about a week without drinking’ (para. 2) and the example of long trips across deserts (para. 5).” Which shows Chen applies the reasons-and-evidence standard?

  1. He explains the author’s point, gives a reason, and cites facts and examples by paragraph. (correct answer)
  2. He shares his own opinion that camels are amazing and lists reasons he would enjoy visiting a desert.
  3. He lists three desert animals from the article but does not explain the reasons the author gives.
  4. He describes the pictures in the article carefully but never connects them to the author’s point.

Explanation: The correct answer shows Chen doing exactly what the standard asks: he names the author’s point (camels survive without much water), gives the reason the author states (they store energy in fat), and backs it up with specific text evidence—a quoted fact and an example, each with a paragraph number. That is analyzing HOW the author uses reasons and evidence, not just retelling the article. Sharing an opinion that camels are amazing and listing reasons to visit a desert is wrong because those are Chen’s own feelings, not an analysis of how the author supports a point. Listing three desert animals is wrong because it only tells what the article mentions and skips the author’s reasons entirely. Describing the pictures carefully is wrong because it focuses on details without ever tying them to the author’s point or the evidence. Only the first answer connects a point, a reason, and real evidence from the text.

Question 5

After reading a how-to article on preventing sunburn, Keisha writes: “The author says sunscreen matters. The author’s evidence is that sunscreen is important.” Does Keisha identify evidence correctly?

  1. Yes; repeating the point counts as evidence in informational texts.
  2. No; she confuses the author’s point with evidence like facts or data. (correct answer)
  3. Yes; she explains the text structure, so evidence is not needed.
  4. No; she should describe the setting and characters to show evidence.

Explanation: This question tests 4th grade writing skills: applying grade 4 reading standards to informational texts, specifically explaining how an author uses reasons and evidence to support particular points in a text (CCSS.W.4.9.b). When students write about informational texts (articles, textbooks, nonfiction), they analyze HOW the author constructs the text, not just WHAT the text says. The standard specifically mentions explaining "how an author uses reasons and evidence to support particular points." This means: identifying the author's main point or claim (what author wants reader to understand), explaining the reasons the author gives (WHY the point is true, the author's explanations), and describing the evidence the author uses (specific facts, statistics, examples, expert opinions, data that prove the reasons). Evidence must be specific proof like facts, statistics, examples, expert opinions, or data—not just restating the point. For example: "The author claims sunscreen prevents sunburn (point). The author gives the reason that sunscreen blocks UV rays (reason). The author provides evidence: the fact that SPF 30 blocks 97% of UV rays, and the study showing people who use sunscreen have 40% fewer sunburns (specific evidence)." Keisha reads a how-to article on preventing sunburn. She identifies that "The author says sunscreen matters" but then states "The author's evidence is that sunscreen is important," which simply restates the point rather than identifying actual evidence. Keisha's analysis confuses the author's point (sunscreen matters/is important) with evidence, when evidence should be specific facts, data, or examples that prove why sunscreen matters. The analysis lacks specific textual support like statistics about UV protection, facts about skin damage, or examples of sunscreen effectiveness. Choice B is correct because Keisha confuses the author's point with evidence like facts or data. She identifies the point ("sunscreen matters") but then restates it ("sunscreen is important") instead of citing actual evidence from the text. Evidence in informational texts must be specific proof—facts ("UV rays cause skin damage"), statistics ("SPF 30 blocks 97% of UV rays"), examples ("A person who forgot sunscreen got severe burns"), or expert opinions ("Dr. Smith says sunscreen reduces cancer risk")—not just repeating that something is important. Keisha could improve by identifying specific facts, data, or examples from the how-to article that show WHY sunscreen matters. Choice A is incorrect because repeating the point ("sunscreen is important" restating "sunscreen matters") does not count as evidence in informational texts; evidence must be specific proof like facts, statistics, or examples that support the point, not just saying the same thing in different words. Students sometimes think restating equals providing evidence, but evidence requires specific information that proves or supports the claim. Using text references with actual facts makes analysis convincing and shows careful reading. To help students apply reading standards to informational texts with focus on reasons and evidence: Distinguish point from evidence explicitly—Point: what author claims ("Sunscreen prevents sunburn"), Evidence: specific proof ("SPF 30 blocks 97% of UV rays" or "Study shows 40% fewer burns with sunscreen use"); teach types of evidence: Facts ("UV rays damage skin cells"), Statistics/Data ("80% of sun damage occurs before age 18"), Examples ("Sarah used SPF 50 and didn't burn at the beach"), Expert opinions ("Dermatologist Dr. Lee recommends daily sunscreen"); practice with real texts: read how-to article together, identify point, then hunt for specific evidence—numbers, facts, examples; use this test: "If I just repeat the point in different words, that's NOT evidence. Evidence answers HOW or WHY with specific information."; provide sentence frames: "The author's point is  . The evidence includes the fact that   [specific fact from text]." Watch for: students who restate points as evidence ("Exercise is good. Evidence: Exercise is healthy"—just restating); students who don't understand evidence must be specific proof; students who don't cite facts, data, or examples from text; teach explicitly that evidence ≠ importance, evidence = proof with specific information from text.

Question 6

After reading a science article on hurricanes, Jamal writes: “The author claims warm water fuels storms. One reason is that warm water adds energy. In paragraph 4, the author says, ‘Water above 80°F can make storms stronger,’ and gives the example of Hurricane Ian growing fast.” Does Jamal apply reasons and evidence?

  1. No; he summarizes hurricanes but does not name any evidence from the text.
  2. Yes; he identifies the claim, a reason, and evidence with a paragraph reference. (correct answer)
  3. No; he only describes the text structure and ignores the author’s point.
  4. Yes; he explains the characters and setting to show the author’s evidence.

Explanation: This question tests 4th grade writing skills: applying grade 4 reading standards to informational texts, specifically explaining how an author uses reasons and evidence to support particular points in a text (CCSS.W.4.9.b). When students write about informational texts (articles, textbooks, nonfiction), they analyze HOW the author constructs the text, not just WHAT the text says. The standard specifically mentions explaining "how an author uses reasons and evidence to support particular points." This means: identifying the author's main point or claim (what author wants reader to understand), explaining the reasons the author gives (WHY the point is true, the author's explanations), and describing the evidence the author uses (specific facts, statistics, examples, expert opinions, data that prove the reasons). For example: "The author claims that recycling helps the environment (point). The author gives the reason that recycling reduces waste in landfills (reason). The author provides evidence: the fact that recycling one ton of paper saves 17 trees, and the statistic that recycling programs have reduced landfill waste by 30% in some cities (specific evidence)." This analysis uses specific text references—facts and statistics from the text—and explains how they support the author's point. Jamal reads a science article on hurricanes. Jamal analyzes how the author uses reasons and evidence. Jamal's analysis identifies the claim that warm water fuels storms, explains the reason that warm water adds energy, cites evidence such as the quote 'Water above 80°F can make storms stronger' from paragraph 4, and provides the example of Hurricane Ian growing fast. For example, Jamal quotes "Water above 80°F can make storms stronger" from the text and references the specific example of Hurricane Ian, which are specific pieces of evidence from the informational text. The analysis includes specific textual support with paragraph references. Choice B is correct because Jamal explains how the author uses reasons and evidence by identifying the author's specific point/claim (warm water fuels storms), explaining the specific reason the author gives (warm water adds energy), citing specific evidence from the text (the quote about 80°F water and the Hurricane Ian example), and providing a paragraph reference. This shows Jamal is analyzing HOW the author constructs the argument, not just summarizing what the text says. Jamal uses textual evidence including specific quotes and examples from the text to support the analysis. Analysis of informational texts requires identifying author's craft (reasons and evidence), using specific text evidence, and explaining how parts work together. Choice A is incorrect because this claims Jamal summarizes hurricanes without naming evidence, when Jamal actually cites specific textual evidence—the quote about 80°F water and the Hurricane Ian example with a paragraph 4 reference. Students sometimes don't recognize specific evidence when it's present. Analyzing how authors use reasons and evidence helps you become a critical reader—you learn to evaluate whether arguments are well-supported. To help students apply reading standards to informational texts with focus on reasons and evidence: Distinguish analysis from summary—summary: "The article is about recycling. It says recycling is good." (WHAT text says); analysis: "The author argues recycling reduces waste (point). The author gives the reason that materials can be reused instead of thrown away (reason). The author provides evidence: the statistic that recycling one aluminum can saves enough energy to power a TV for 3 hours (specific evidence from text)." (HOW author uses reasons and evidence); practice with texts: read informational article together, identify: What is author's main point? What reasons does author give for this point? What specific evidence (facts, data, examples) does author provide?; teach types of evidence explicitly—Facts (can be verified), Statistics/Data (numbers, percentages), Examples (specific instances), Expert opinions (what authorities say), Descriptions (detailed explanations); require text references: "You must cite specific evidence from text: quote it, reference the page, or describe the specific fact/data/example."; analyze other standards too: text structure (cause-effect, compare-contrast, sequence), main idea support (how details support), text features (how headings, diagrams help); emphasize: Informational text analysis focuses on HOW author constructs text, not just summarizing content; always use specific text evidence; connect reasons and evidence to author's point. Watch for: students who confuse narrative analysis with informational analysis (trying to analyze "characters" in science article); students who don't understand difference between reason (explanation of why) and evidence (proof with facts/data); students who don't use text references (quotes, page numbers, specific facts); students who list evidence without explaining how it supports author's point; teach explicitly: Author's Point (claim) + Reasons (why) + Evidence (proof with facts/data/examples) = how author supports points in informational text; Model frequently with real articles; Give graphic organizers; Require text citations always; Emphasize this is about HOW author builds argument, not just WHAT text says.

Question 7

After reading a textbook section on recycling, Sofia writes: “Recycling is important. The author gives reasons and evidence. It is a good idea and everyone should do it.” Does Sofia apply the standard about reasons and evidence? Why or why not?

  1. Yes, because she clearly names two facts and a statistic that the author includes in the text.
  2. No, because she gives no specific reasons, evidence, or references to the actual text. (correct answer)
  3. Yes, because she uses strong feelings and opinion words to convince her readers.
  4. No, because she should retell the story's events in the order they happen.

Explanation: Sofia's writing only says the author "gives reasons and evidence," but she never names a single reason or fact from the recycling section. That is why the best answer is that she gives no specific reasons, evidence, or references to the actual text. To apply the standard, she would need to point to the actual reasons the author gives and the actual facts or numbers that back them up. Saying she names two facts and a statistic is wrong because Sofia does not name any facts or numbers at all—she only makes a general comment. Saying she uses strong feelings is wrong too: sharing feelings or opinions is not the same as explaining how an author uses reasons and evidence. The choice about retelling events in order is also wrong, because a textbook section on recycling explains ideas rather than telling a story, so there are no events to retell. Only one answer matches what the standard really asks.

Question 8

Read Maya’s analysis of an article on saving water: “The author claims shorter showers save water. The author’s reason is showers use many gallons. The author gives evidence: ‘a 10-minute shower uses about 25 gallons’ (para. 2) and a chart showing a 5-minute shower uses about half (caption).” Does Maya explain reasons and evidence well?

  1. No, because she only summarizes the topic and never states the claim, reason, or any fact the author uses.
  2. Yes, because she names the claim, gives the reason, and backs it with a fact and a chart caption. (correct answer)
  3. No, because she describes the article’s text structure instead of the claim, reason, and evidence the author gives.
  4. Yes, because she explains that saving water is important, even though she lists no reason, fact, or chart caption.

Explanation: The best answer is that Maya names the claim, gives the reason, and backs it with a fact and a chart caption. She does exactly what good analysis needs: she states the author’s point (shorter showers save water), gives the author’s reason (showers use many gallons), and supports it with real evidence—the quoted fact about 25 gallons and the chart caption. That shows how the author builds the argument. The choice saying she only summarizes and never states the claim or evidence is wrong—Maya clearly names the claim and quotes a fact, so this misreads what she did. The choice saying she describes text structure is wrong because Maya never talks about how the article is organized; she discusses the reason and evidence instead. The choice saying she just explains that water is important is wrong because Maya does far more than share a general idea—she uses specific numbers and a caption. Only one answer matches everything Maya actually included.

Question 9

Yuki reads an article about saving energy at home. She writes: “The author’s point is turning off lights saves energy. The author’s reason is it lowers electricity use. In section ‘Save Power,’ the author gives data: ‘Families can cut bills by 10% when they switch to LED bulbs.’” Does Yuki use text evidence?

  1. No; she only gives her own opinion and no facts.
  2. Yes; she includes a section title and a statistic that supports the point. (correct answer)
  3. No; she only explains the article’s sequence and not the author’s point.
  4. Yes; she explains the main character’s actions to prove the author’s evidence.

Explanation: This question tests 4th grade writing skills: applying grade 4 reading standards to informational texts, specifically explaining how an author uses reasons and evidence to support particular points in a text (CCSS.W.4.9.b). When students write about informational texts (articles, textbooks, nonfiction), they analyze HOW the author constructs the text, not just WHAT the text says. The standard specifically mentions explaining "how an author uses reasons and evidence to support particular points." This means: identifying the author's main point or claim (what author wants reader to understand), explaining the reasons the author gives (WHY the point is true, the author's explanations), and describing the evidence the author uses (specific facts, statistics, examples, expert opinions, data that prove the reasons). For example: "The author claims that recycling helps the environment (point). The author gives the reason that recycling reduces waste in landfills (reason). The author provides evidence: the fact that recycling one ton of paper saves 17 trees, and the statistic that recycling programs have reduced landfill waste by 30% in some cities (specific evidence)." This analysis uses specific text references—facts and statistics from the text—and explains how they support the author's point. Yuki reads an article about saving energy at home. Yuki analyzes how the author uses reasons and evidence. Yuki's analysis identifies the point that turning off lights saves energy, explains the reason it lowers electricity use, cites evidence such as the data 'Families can cut bills by 10% when they switch to LED bulbs' from section 'Save Power,' and explains the connection. For example, Yuki cites the specific data that families can cut bills by 10% when they switch to LED bulbs, which is specific evidence from the informational text. The analysis includes specific textual support with section references. Choice B is correct because Yuki includes a section title and a statistic that supports the point by citing specific evidence from the text (the 10% statistic about LED bulbs), referencing where it comes from (section 'Save Power'), and connecting it to the author's point about saving energy. This shows Yuki is analyzing HOW the author constructs the argument, not just summarizing what the text says. Yuki uses textual evidence including specific data from the text to support the analysis. Analysis of informational texts requires using specific text evidence. Choice A is incorrect because this claims Yuki only gives her own opinion and no facts, when Yuki actually cites specific textual evidence—the 10% statistic about LED bulbs from the 'Save Power' section. Students sometimes don't recognize specific evidence when it's present. Analyzing how authors use reasons and evidence helps you become a critical reader—you learn to evaluate whether arguments are well-supported. To help students apply reading standards to informational texts with focus on reasons and evidence: Distinguish analysis from summary—summary: "The article is about recycling. It says recycling is good." (WHAT text says); analysis: "The author

Question 10

Marcus writes about a social studies article on voting: “The author wants people to vote. The author gives reasons. The author uses evidence.” What should Marcus add to meet the reasons-and-evidence standard?

  1. A specific reason and a quoted fact or statistic from the article. (correct answer)
  2. A drawing of a voting booth and a caption about his feelings.
  3. A prediction about what will happen in the next chapter.
  4. A longer summary that retells the article from start to finish.

Explanation: This question tests 4th grade writing skills: applying grade 4 reading standards to informational texts, specifically explaining how an author uses reasons and evidence to support particular points in a text (CCSS.W.4.9.b). When students write about informational texts (articles, textbooks, nonfiction), they analyze HOW the author constructs the text, not just WHAT the text says. The standard specifically mentions explaining "how an author uses reasons and evidence to support particular points." This means: identifying the author's main point or claim (what author wants reader to understand), explaining the reasons the author gives (WHY the point is true, the author's explanations), and describing the evidence the author uses (specific facts, statistics, examples, expert opinions, data that prove the reasons). For example: "The author claims that recycling helps the environment (point). The author gives the reason that recycling reduces waste in landfills (reason). The author provides evidence: the fact that recycling one ton of paper saves 17 trees, and the statistic that recycling programs have reduced landfill waste by 30% in some cities (specific evidence)." This analysis uses specific text references—facts and statistics from the text—and explains how they support the author's point. Marcus reads a social studies article on voting. Marcus analyzes how the author uses reasons and evidence. Marcus's analysis states the author wants people to vote and mentions the author gives reasons and uses evidence, but provides vague statements without specific text references. For example, Marcus makes general statements "author gives reasons" and "author uses evidence" without specifics. The analysis is vague without text citations. Choice A is correct because Marcus should add a specific reason and a quoted fact or statistic from the article. This shows Marcus needs to identify the specific reasons author actually gives in text and cite specific evidence (facts, statistics, examples) with quotes or references. Marcus could improve by adding text references to show where information comes from and explaining how the evidence supports the author's reasons and point. Analysis of informational texts requires using specific text evidence. Choice B is incorrect because this suggests Marcus needs a drawing of a voting booth and a caption about his feelings, when strong analysis requires specific reasons and evidence from text, not drawings or personal feelings. Students sometimes give own opinions instead of analyzing author's approach. Analyzing how authors use reasons and evidence helps you become a critical reader—you learn to evaluate whether arguments are well-supported. To help students apply reading standards to informational texts with focus on reasons and evidence: Teach the three-part structure explicitly—Author's Point/Claim (what author wants reader to understand or believe), Reasons (WHY the point is true—author's explanations), Evidence (PROOF—facts, statistics, examples, expert quotes, data); use graphic organizer: top box: Author's Point, middle boxes: Reason 1, Reason 2, bottom boxes under each reason: Evidence (specific facts, data, examples); model with think-aloud: "I'm reading this article about why exercise is important. The author's point is: Everyone should exercise regularly. Now I'll find the reasons the author gives: Reason 1: Exercise keeps your heart healthy. What evidence does author give? The author states the fact that people who exercise 30 minutes daily have 40% lower risk of heart disease. That's specific evidence—a fact with a number. Reason 2: Exercise improves mood. Evidence: The author cites a study by Dr. Smith showing exercise releases endorphins. That's evidence—an expert opinion."; require specificity: "Don't write 'author gives reasons.' Write 'The author gives the reason that...' and state the actual reason from the text."; provide sentence frames: "The author claims/argues that   (point). The author gives the reason that   (reason). The author supports this with evidence:   (specific fact, statistic, example, or quote from text, with page number)."; teach text references: "Every time you mention evidence, cite it: use quotation marks for quotes, or say 'The text states that...' or 'According to the article (page X)...' ". Watch for: students who summarize ("The text is about...") instead of analyze ("The author uses..."); students who make vague statements ("author gives reasons") without identifying what reasons; students who don't cite specific evidence from text; students who give their own opinions instead of analyzing author's approach.

Question 11

After reading a social studies article about voting, Amir writes: “The author says voting matters. The author gives reasons like it helps choose leaders. The author uses evidence.” What is missing from Amir’s analysis of reasons and evidence?

  1. Specific facts, examples, or quotes from the article that prove the author's reasons. (correct answer)
  2. A prediction about what the author thinks will happen in the next election.
  3. A summary that retells all the main events from the article in order.
  4. Stronger opinion words that make the author's point sound more exciting.

Explanation: When you analyze how an author uses reasons and evidence, you show the actual proof from the text. Amir names the point (voting matters) and a reason (it helps choose leaders), but he only says “the author uses evidence” without telling what that evidence is. So the missing piece is the specific facts, examples, or quotes from the article that prove the reasons—like a statistic or a real example the author included. Adding a prediction about the next election is wrong because analyzing evidence means showing proof already in the text, not guessing about the future. Writing a summary that retells the events is wrong because a summary tells WHAT the article says, while Amir's job is to show HOW the author backs up the point with proof. Adding stronger opinion words is wrong because exciting words are just Amir's opinion; they are not facts or examples from the article that prove anything. To improve, Amir should quote or name the specific evidence the author gave.

Question 12

Read Maya’s analysis of an article about clean drinking water; which shows strong reasons and evidence?

  1. The author’s point is that water is important. A reason is we need it every day, and I learned a lot from reading the whole article about it.
  2. The author’s point is filters make water safer. A reason is they remove germs, and in paragraph 3 the author states, ‘Boiling kills most bacteria,’ giving a town flood example. (correct answer)
  3. The author’s point must be strong because the article uses headings, bold words, and pictures that help me read all the facts in each section clearly.
  4. The author’s point is that tap water is fine. A reason is that I disagree with the writer because I really like the taste of my own tap water at home.

Explanation: The best answer names the author’s point (filters make water safer), gives a reason (they remove germs), and backs it up with real evidence from the text — a quote from paragraph 3 and an example about a town boiling water during floods. That is how you explain HOW an author uses reasons and evidence. The choice about water being important sounds like a summary, but it never cites any reason or evidence from the article — it just says the writer talked about water and that the reader learned a lot. The choice about headings, bold words, and pictures points to text features, not the author’s actual reasons and evidence, so it judges the writing by how it looks instead of what it proves. The choice about tap water gives the reader’s own opinion and taste, not the author’s reasons or any facts from the text. Only one answer identifies the point, the reason, and specific evidence from the article, so it is the strongest analysis.

Question 13

After reading a nonfiction book about hurricanes, Carlos writes, “The author’s point is that preparing early keeps people safe. The author gives the reason that storms can change direction quickly. On page 12, it says, ‘A hurricane can shift its path in a few hours,’ and it lists supplies like water and flashlights.” Which shows Carlos uses reasons and evidence best?

  1. He names the point, gives a reason, and cites a page 12 quote and examples. (correct answer)
  2. He says hurricanes are scary and that he really dislikes stormy, windy weather.
  3. He retells each step of the storm in order but never explains what supports the point.
  4. He explains only that the book uses helpful headings, diagrams, and bold vocabulary words.

Explanation: The best answer shows Carlos naming the author’s point (preparing early keeps people safe), giving the author’s reason (storms can change direction quickly), and backing it up with the page 12 quote and the supply examples. That is exactly how you explain how an author uses reasons and evidence. The choice about hurricanes being scary and disliking stormy weather only shares Carlos’s personal feelings; feelings are not the author’s reasons or evidence. The choice that retells each step of the storm in order is just a summary of what happened—it never explains what supports the author’s point, so it is not analysis. The choice about headings, diagrams, and bold words names text features but skips the point, the reason, and the evidence the author uses to prove it. Only the first choice does all three, so it is the single best answer.

Question 14

After reading a science article on bees, read Emma’s analysis: She wrote, “The author’s point is bees help plants grow. One reason is bees move pollen. The author proves it with the fact ‘one bee can visit 5,000 flowers a day’ (para. 3) and an example of apple orchards needing bees (para. 4).” Does Emma explain how the author uses reasons and evidence? Why or why not?

  1. No, she only shares her own feelings about bees and never uses any details from the paragraphs.
  2. Yes, she gives the main idea, a reason, and specific facts pulled from the article. (correct answer)
  3. No, she just lists the section titles and headings instead of the reasons and proof the author gives.
  4. Yes, because she carefully retells the story events in order from beginning to middle to end.

Explanation: The best answer is the one saying Emma gives the main idea, a reason, and specific facts from the article. Emma names the author's point (bees help plants grow), gives a reason (bees move pollen), and backs it up with real proof: the fact that one bee visits 5,000 flowers a day and the apple orchard example. That is exactly what it means to explain how an author uses reasons and evidence. The choice saying she only shares her feelings is wrong, because Emma does not give opinions—she quotes actual facts and points to the paragraphs. The choice saying she lists section titles and headings is wrong, because Emma never mentions headings; she names reasons and evidence instead. The choice saying she retells story events in order sounds right because it starts with "Yes," but it is wrong: Emma analyzes how the author supports a point, and this article is informational, not a story with beginning-middle-end events. Watch for answers that sound agreeable but describe the wrong kind of writing.

Question 15

Read Jamal’s analysis of an article about hurricanes: “The author claims people should prepare early. The author’s reason is storms can change fast. The evidence is ‘winds can reach 74 miles per hour’ and ‘weather scientists track storms by satellite’ (section ‘Watch the Storm’).” Which text evidence does Jamal use?

  1. Specific facts he quotes about wind speed and about how scientists follow storms. (correct answer)
  2. A made-up story about a brave kid who rode out a big storm with his dog.
  3. The author's personal opinion that hurricanes are the most terrifying kind of storm.
  4. A colorful diagram of the water cycle copied from a different weather science book.

Explanation: The right answer names the specific facts Jamal quotes from the article—one about how fast the wind can blow and one about how scientists follow storms. Evidence means the real facts and details an author gives to back up a point, and Jamal points to exactly those facts from the text. The story about a kid and his dog is wrong because that is make-believe from a narrative, not a fact from this informational article. The author's opinion that hurricanes are the scariest storm is wrong because an opinion is what someone feels, not evidence you can check. The water-cycle diagram is wrong because it comes from a different book and never appears in Jamal's article, so it cannot be the evidence he used. Only the quoted facts about wind speed and satellite tracking are the actual text evidence Jamal cites.

Question 16

Chen analyzes an article on recycling. He writes: “The author’s point is recycling saves resources. The author’s reason is it reduces new mining. On page 2, it says, ‘Recycling one aluminum can saves enough energy to run a TV for three hours.’” Which evidence did Chen cite?

  1. A number showing how much energy is saved, found on a page of the article. (correct answer)
  2. A made-up character’s spoken words from a fun story about a hero who loves recycling.
  3. A bold title at the top of a section that tells readers to help our planet today.
  4. A dated chart showing the order of events in recycling history over many long years.

Explanation: The correct answer is the number showing how much energy is saved, found on a page of the article. Evidence in an informational text means specific facts or data an author uses to support a point. Chen quotes an exact fact with a number—how much energy recycling one can saves—and tells the page where he found it. That is a statistic used as evidence. The made-up character’s spoken words from a story are wrong because a character quote comes from fiction, not from an informational article, and Chen is analyzing a nonfiction text. The bold title at the top of a section is wrong because a heading tells you what a part is about; it is a text feature, not a fact or number that proves the author’s point. The dated chart showing the order of events is wrong because Chen never mentions a timeline, and the fact he quotes is about energy savings, not about when recycling began. Only the choice that names a specific fact with a number, taken from a page of the article, matches the evidence Chen actually cited.

Question 17

After reading a nonfiction book about wolves, Yuki writes: “The author’s point is wolves help ecosystems. The author’s reason is wolves keep deer from eating too many plants. The author’s evidence is the fact ‘after wolves returned, more young trees grew near rivers’ (p. 18) and an example of more beavers building dams (p. 19).” Which text evidence does Yuki cite?

  1. The fact that more young trees grew near rivers and the example of more beavers building dams after wolves came back. (correct answer)
  2. The reason that wolves keep deer from eating too many of the plants that grow in the forest.
  3. The point that wolves are helpful animals because they keep the whole ecosystem healthy and balanced.
  4. The opinion that wolves are the most interesting animals to read about in a nonfiction book.

Explanation: Yuki’s writing names three parts: a point, a reason, and evidence. The question asks only for the evidence, which is the proof the author gives. The best answer names the fact about more young trees growing near rivers and the example of more beavers building dams—these are the specific facts and examples the author uses as proof. The choice about wolves keeping deer from eating too many plants is Yuki’s reason, which tells WHY the point is true, not the evidence that proves it. The choice about wolves keeping the ecosystem healthy is Yuki’s point, the main idea the author wants you to believe—not the evidence. The choice calling wolves the most interesting animals is an opinion, and Yuki never wrote that; an opinion is not text evidence at all. To find evidence, look for the actual facts and examples, like the trees and beavers, that back up the author’s ideas.

Question 18

Read Emma’s analysis of an article on saving sea turtles; does she explain reasons and evidence?

  1. Yes; she names the claim and uses two facts, explaining how they support it. (correct answer)
  2. No; she only retells the main idea and never explains the author’s reasons.
  3. Yes; she names two facts, but she never links them back to the author’s claim.
  4. No; she describes the article’s headings instead of the reasons and evidence.

Explanation: The best answer says Emma names the claim and uses two facts, explaining how they support it. That is exactly what good analysis of an informational text does: it points out the author’s claim, gives the facts the author uses as evidence, and shows how those facts back up the claim. Emma does all three parts, so she truly explains reasons and evidence. The choice saying she only retells the main idea is wrong because retelling what an article is about is not the same as explaining the author’s reasons—and Emma actually does explain them. The choice saying she names two facts but never links them to the claim is wrong because it is a partial truth: Emma does more than list facts—she explains how each fact supports the author’s point. The choice saying she describes the article’s headings is wrong because headings are just labels for sections; noticing them is not the same as analyzing the author’s reasons and evidence, which is what Emma actually did. So the only choice that fully matches what Emma’s analysis does is the one about naming the claim and explaining how two facts support it.

Question 19

Riley analyzes a how-to article on saving water: “The author’s point is to use less water at home. The author’s reason is that water is limited in some places. The author gives evidence: ‘A dripping faucet can waste 3,000 gallons a year’ (paragraph 5).” Which part is the evidence?

  1. “Everyone should use less water at home” (paragraph 1).
  2. “Water is limited in some places on Earth” (paragraph 2).
  3. “A dripping faucet can waste 3,000 gallons a year” (paragraph 5). (correct answer)
  4. “Saving water is a smart habit for families” (paragraph 8).

Explanation: Evidence is a specific fact, number, or example that proves an author's reason. The line “A dripping faucet can waste 3,000 gallons a year” is evidence because it gives an exact amount (3,000 gallons) that shows how much water can be wasted. That number backs up the author's reason. The choice “Everyone should use less water at home” is the author's point—what the author wants readers to do. It tells you the goal, but it does not prove anything with facts, so it is not evidence. The choice “Water is limited in some places on Earth” is the reason—it explains why the point matters. A reason tells you WHY, but it still has no facts or numbers, so it is not the evidence. The choice “Saving water is a smart habit for families” is just an opinion. It sounds nice, but there is no fact or number to prove it, so it cannot be the evidence. Only the faucet line gives real data, so it is the evidence. Don't be fooled by a paragraph number—every choice has one. Look for the fact with numbers instead.
