Question 1

Chen is researching: "How do wildfires affect air quality?" He is choosing between two sources.

Source A: A 2023 article from the U.S. Environmental Protection Agency (EPA) website explaining particulate matter (PM2.5), with data links and a publication date.
Source B: A 2020 social media thread by an influencer with no science training, claiming "smoke is basically harmless" and providing no evidence.

Which choice BEST compares the credibility of these sources?

  1. Source B is more credible because it is written in simpler language for the public.
  2. Source A is more credible because it is from a reputable government agency and provides evidence and dates. (correct answer)
  3. They are equally credible because both are online and discuss the same topic.
  4. Source B is more credible because it has more comments and shares.
Explanation: This question tests W.7.8—gather information from multiple sources, assess credibility/accuracy, quote/paraphrase avoiding plagiarism, follow citation format. Research requires: MULTIPLE CREDIBLE SOURCES (3-5 different: books, databases, credible websites, primary sources; assess credibility: author credentials/expert?, reputable publisher?, current date for current topics?, purpose/bias considered?—avoid unreliable: Wikipedia only, random blogs, no author, out-of-date, clearly biased unacknowledged), PROPER USE (quote: exact words in quotation marks with citation, paraphrase: own words with citation—change structure not just synonyms, summarize: main ideas with attribution—integrate smoothly), AVOID PLAGIARISM (cite all sources, don't copy word-for-word without quotes, put into own words when paraphrasing, attribute ideas), STANDARD CITATION (format taught: author, title, publication info, date, proper punctuation, parenthetical in text, works cited page). Chen compares EPA website (government agency, 2023, provides data) versus social media post (influencer without science training, unsupported claims). Source A is more credible because government agencies like EPA employ experts, provide evidence-based information, cite data sources, and update content regularly. Source B lacks credibility due to no scientific expertise, no evidence provided, and potentially dangerous misinformation about smoke being "harmless." Students should recognize that credible sources have qualified authors/organizations, provide evidence for claims, come from reputable publishers, and avoid unsupported opinions—social media engagement (comments/shares) doesn't indicate credibility.

Question 2

Carlos is creating a Works Cited page in MLA for a website article. He has this entry:

"Climate Change Effects." 2021. www.climatefacts.org.

What is the MOST important information missing for a correct MLA citation?

  1. The author (or organization) and the date the page was published or updated. (correct answer)
  2. A long summary of the article's main ideas.
  3. The student's opinion about whether the website is trustworthy.
  4. A list of other websites that talk about the same topic.
Explanation: This question tests W.7.8—gather information from multiple sources, assess credibility/accuracy, quote/paraphrase avoiding plagiarism, follow citation format. Research requires: MULTIPLE CREDIBLE SOURCES (3-5 different: books, databases, credible websites, primary sources; assess credibility: author credentials/expert?, reputable publisher?, current date for current topics?, purpose/bias considered?—avoid unreliable: Wikipedia only, random blogs, no author, out-of-date, clearly biased unacknowledged), PROPER USE (quote: exact words in quotation marks with citation, paraphrase: own words with citation—change structure not just synonyms, summarize: main ideas with attribution—integrate smoothly), AVOID PLAGIARISM (cite all sources, don't copy word-for-word without quotes, put into own words when paraphrasing, attribute ideas), STANDARD CITATION (format taught: author, title, publication info, date, proper punctuation, parenthetical in text, works cited page). Carlos's MLA citation lacks author information—the most critical missing element for proper attribution and allowing readers to locate the source. MLA format requires: Author (or organization if no individual author). "Title." Website Name, Date, URL—his entry shows only title, date, and URL. Options B, C, and D suggest inappropriate additions—Works Cited entries need factual information not summaries or opinions, and listing related websites isn't part of standard citation format. Students must learn proper citation formats include specific required elements in specific order, author/organization is crucial for credibility and location, and personal opinions don't belong in citations.

Question 3

Amir is writing about how caffeine affects sleep. He found this sentence in a medical website article:

"Caffeine has a half-life of about five hours in healthy adults, meaning it can stay in your system long after you drink it."

Amir writes in his report:

Caffeine has a half-life of about five hours in healthy adults, meaning it can stay in your system long after you drink it.

He does not use quotation marks or a citation. What best describes Amir's use of the source?

  1. This is acceptable because scientific information is common knowledge and never needs a citation
  2. This is direct plagiarism because he copied the sentence word-for-word without quotation marks or citation (correct answer)
  3. This is a strong paraphrase because he kept the same structure to avoid changing the meaning
  4. This is not plagiarism as long as he lists the website somewhere, even without an in-text citation
Explanation: This question tests W.7.8—gather information from multiple sources, assess credibility/accuracy, quote/paraphrase avoiding plagiarism, follow citation format. Research requires: MULTIPLE CREDIBLE SOURCES (3-5 different: books, databases, credible websites, primary sources; assess credibility: author credentials/expert?, reputable publisher?, current date for current topics?, purpose/bias considered?—avoid unreliable: Wikipedia only, random blogs, no author, out-of-date, clearly biased unacknowledged), PROPER USE (quote: exact words in quotation marks with citation, paraphrase: own words with citation—change structure not just synonyms, summarize: main ideas with attribution—integrate smoothly), AVOID PLAGIARISM (cite all sources, don't copy word-for-word without quotes, put into own words when paraphrasing, attribute ideas), STANDARD CITATION (format taught: author, title, publication info, date, proper punctuation, parenthetical in text, works cited page). Amir copied the medical website's sentence word-for-word without any changes, quotation marks, or citation—this is direct plagiarism, the most serious form of academic dishonesty. The correct answer identifies this as copying verbatim without attribution. Option A wrongly claims scientific information needs no citation; option C misidentifies this as paraphrasing when no words were changed; option D incorrectly suggests a bibliography alone prevents plagiarism without in-text citations. Students must understand that using someone else's exact words requires quotation marks AND citation, while using their ideas in your own words requires citation. Teaching plagiarism prevention means showing clear examples of word-for-word copying versus proper quoting (with quotation marks and citation) and proper paraphrasing (significant rewording with citation), emphasizing that all borrowed information needs attribution.

Question 4

Maya is writing a 7th-grade report answering: "How does plastic pollution affect ocean animals?" She found these sources:

Source 1: National Oceanic and Atmospheric Administration (NOAA) web page, "Marine Debris" (no individual author listed), updated 2024, .gov, explains impacts and prevention.
Source 2: Blog post on OceanTruthNow.com, "The Ocean Will Be Dead by 2030," posted 2012, author listed as "SeaLover99," includes many ads and no references.
Source 3: Peer-reviewed journal article in Marine Pollution Bulletin (2019) by two university scientists; includes methods and a reference list.
Source 4: Wikipedia page "Great Pacific Garbage Patch," last edited yesterday.

Which source is the MOST credible to use for scientific evidence about impacts on ocean animals?

  1. Source 1, because it is a government agency web page that is up to date, though it lists no individual author.
  2. Source 4, because it was edited very recently and gathers information from many contributors into one place.
  3. Source 3, because it is peer-reviewed and written by qualified researchers. (correct answer)
  4. Source 2, because it is passionate about the topic and states its predictions with confidence.
Explanation: The best choice is the peer-reviewed journal article written by qualified researchers. Peer review means other experts checked the work before it was published, and the article includes methods and a reference list, so it is the strongest source for scientific evidence. The government agency page is reliable and current, but with no individual author and a general audience it is not as strong for detailed scientific evidence as a study reviewed by experts. The Wikipedia page can be edited by anyone, so a recent edit and many contributors do not guarantee accuracy—it is a starting point, not evidence. The blog post is the weakest option: being passionate and confident about a prediction is not proof, and with an anonymous author, a 2012 date, lots of ads, and no references, it fails almost every credibility test. When choosing sources for a scientific topic, look for expert authors, review or references, and a purpose focused on informing rather than persuading.

Question 5

Riley is writing about the Dust Bowl for a history assignment. She uses two sources:

Source 1: A 2015 textbook chapter published by a major educational publisher. Source 2: A 1936 newspaper article written during the Dust Bowl.

Which is the BEST reason Source 2 can still be accurate and useful even though it is old?

  1. Older sources are always more reliable than newer ones.
  2. It is a primary source that provides firsthand information from the time period. (correct answer)
  3. It does not need to be checked because newspapers never contain errors.
  4. It is better than a textbook because it will automatically be unbiased.
Explanation: This question tests W.7.8—gather information from multiple sources, assess credibility/accuracy, quote/paraphrase avoiding plagiarism, follow citation format. Research requires: MULTIPLE CREDIBLE SOURCES (3-5 different: books, databases, credible websites, primary sources; assess credibility: author credentials/expert?, reputable publisher?, current date for current topics?, purpose/bias considered?—avoid unreliable: Wikipedia only, random blogs, no author, out-of-date, clearly biased unacknowledged), PROPER USE (quote: exact words in quotation marks with citation, paraphrase: own words with citation—change structure not just synonyms, summarize: main ideas with attribution—integrate smoothly), AVOID PLAGIARISM (cite all sources, don't copy word-for-word without quotes, put into own words when paraphrasing, attribute ideas), STANDARD CITATION (format taught: author, title, publication info, date, proper punctuation, parenthetical in text, works cited page). Riley's 1936 newspaper article serves as a primary source—firsthand account from the actual time period of the Dust Bowl, providing contemporary perspectives and observations unavailable in later secondary sources. Primary sources offer unique historical value regardless of age because they capture events as they happened. Options A, C, and D contain misconceptions—newer isn't always better for historical events, newspapers can contain errors/bias requiring critical reading, and primary sources can reflect period biases. Students should understand primary sources (diaries, newspapers, photographs from the time) versus secondary sources (textbooks, analyses written later), recognize both types have value, and evaluate all sources critically regardless of type or age.

Question 6

Keisha is researching: "What are the benefits and risks of using AI chatbots in school?" She finds a web article with these details:

Title: "Why Students Should Use AI for Everything" Author: Not listed Date: Not listed Website: BestEdTechDeals.com Content: Mostly product links and discounts; claims "AI always improves grades" with no studies cited.

What is the BIGGEST credibility problem with this source?

  1. It has no listed author or date and cites no studies, so it may be trying to sell products rather than inform readers fairly. (correct answer)
  2. It is trustworthy because it takes a clear side and confidently supports letting students rely on AI, which is a helpful topic.
  3. It is trustworthy because it links to many current products and comes from a website that clearly focuses on education tools.
  4. It is a minor concern that the author and date are missing, but the detailed content and strong claims still make it reliable overall.
Explanation: The best answer points to the real red flags: no author or date means you cannot check who wrote it or whether it is current, and no cited studies means its big claim ("AI always improves grades") is unsupported. Combined with a website full of product links and discounts, the source seems built to sell things, not to inform you honestly. The choice saying it is trustworthy because it takes a clear side is wrong—supporting one position, especially without evidence, does not make a source credible; a strong opinion is not proof. The choice praising many product links and an education-focused site is wrong because commercial sites that push products often prioritize sales over accuracy, and links to deals are not the same as reliable information. The last choice is wrong because a missing author and date are not minor issues; you cannot verify a source or its claims when both are absent, and confident wording does not replace evidence. To judge credibility, look for a named author, a date, and real evidence behind the claims.

Question 7

Carlos is writing about the Dust Bowl. He uses three sources: (1) a 1930s photograph from the Library of Congress, (2) a chapter from a history book, and (3) a museum website article written by a historian. In his draft, he includes a sentence that closely follows the museum article's wording but changes a few words:

Museum article: "Severe drought and poor farming practices turned millions of acres of topsoil into dust, forcing many families to migrate west." Carlos's draft: "Extreme drought and bad farming methods turned millions of acres of topsoil into dust, forcing lots of families to move west."

He includes no citation. What is the best description of the problem?

  1. There is no problem here, because he swapped in several new words, so the sentence now counts as his own original writing without a citation
  2. This is too-close paraphrasing plus a missing citation; he should rewrite it in his own structure and credit the museum article (correct answer)
  3. The only real problem is that a photograph and a history book cannot be mixed with a website in the same research paper
  4. This is acceptable, because the historian who wrote the article already did the citing, so Carlos does not have to cite it again
Explanation: The best answer names both problems at once: Carlos kept the museum article's exact sentence structure and only swapped in synonyms ("extreme" for "severe," "bad" for "poor," "lots" for "many," "move" for "migrate"), which is still copying the original idea and wording too closely. On top of that, he added no citation. Real paraphrasing means rebuilding the sentence in your own structure AND crediting where the idea came from. The option that says swapping words makes it his own writing is wrong: changing a few synonyms while keeping the same structure is patchwriting, not original work, and it still needs a citation. The option claiming the only problem is mixing a photograph, a book, and a website is wrong too—using several different source types is exactly what good research does. The option saying Carlos does not have to cite because the historian already cited things misunderstands citation: every writer must credit the sources they personally borrow from, no matter what those sources did.

Question 8

Chen is comparing two sources for a report on earthquakes:

Source A: A U.S. Geological Survey (USGS) page explaining earthquake magnitude and intensity, updated 2022.
Source B: A 2008 forum post where users argue about whether earthquakes are caused by "secret machines," with no evidence or expert names.

Which statement best compares the credibility of the two sources?

  1. Source B is more credible because it presents many different user opinions in one place, and hearing several viewpoints makes a source more balanced and trustworthy
  2. Source A is more credible because it comes from a government science agency and was updated recently, while Source B lacks evidence and expert authorship (correct answer)
  3. Both sources are equally credible because they are both available online and both directly discuss the topic of earthquakes that Chen is researching
  4. Source B is more credible because it was published earlier, and older sources on scientific topics are generally more accurate than newer ones
Explanation: The strongest choice recognizes that a U.S. Geological Survey page comes from the official government agency that studies earthquakes, was updated recently in 2022, and offers factual, expert information. That combination—expert authorship, a reputable publisher, and a current date—makes it far more credible than the forum post, which has no named experts and no evidence. The choice claiming Source B is better because it collects many user opinions is wrong: a pile of unsupported opinions is not the same as balanced, reliable information, especially when none of the posters are experts and none offer evidence. The choice saying both are equally credible fails because being online and being on-topic tell you nothing about quality; a credible source and a conspiracy-theory forum can both appear online yet differ hugely in trustworthiness. The choice preferring Source B because it is older reverses a key rule: for scientific topics, more recent sources usually reflect updated knowledge, so an older forum post is not automatically more accurate. Judging credibility means checking who wrote a source, whether they provide evidence, and whether the information is current.

Question 9

Jordan is summarizing information about why bees are important. He reads this from a credible science website:

Original: "Pollinators like bees help many plants reproduce by moving pollen between flowers, which supports ecosystems and food crops."

Jordan writes: Pollinators such as bees help plants reproduce by moving pollen from flower to flower, supporting ecosystems and many food crops (Smith, 2021).

Which statement BEST describes Jordan's writing?

  1. It is acceptable because he swapped in a few different words, so putting his own citation on it is optional here.
  2. It is a good paraphrase with a citation, so it avoids plagiarism and credits the original source. (correct answer)
  3. It is plagiarism because he kept too much of the original meaning, so a paraphrase like this still counts as copying.
  4. It is unnecessary because he added a citation, so restating the idea in his own words was extra work he could skip.
Explanation: The best answer says Jordan wrote a good paraphrase with a citation. He changed the sentence structure and wording ("like" to "such as," "between flowers" to "from flower to flower") while keeping the meaning, and he credited the source with (Smith, 2021). That is exactly how to paraphrase without plagiarizing. The choice saying a citation is optional because he changed a few words is wrong: any time you use someone else's idea, you must cite it, even after rewording. The choice calling it plagiarism because he kept the meaning is wrong: a paraphrase is supposed to keep the original meaning while changing the words and structure, and a citation makes it honest, not copied. The choice saying paraphrasing was unnecessary work he could skip is wrong: a citation alone does not let you copy wording, so putting the idea into your own words is a required part of paraphrasing, not extra effort. Good research writing combines both moves Jordan made—rewording in your own voice AND citing the source.

Question 10

Marcus is researching: "Should schools ban junk food in vending machines?" He uses these sources:

  1. A peer-reviewed nutrition study (2021) about student snack choices.
  2. A government health site (.gov) page updated 2023 about added sugar.
  3. An opinion article from a candy company's website arguing bans are unfair.
  4. A random forum post with no author saying "sugar is a myth."

Which research plan BEST shows Marcus assessing credibility and accuracy before using information?

  1. Treat all four sources as equally trustworthy, since each one discusses snacks or sugar and giving them the same weight keeps his research balanced and fair.
  2. Rely mainly on the candy company article and the forum post, since both express strong views and give a real sense of what people actually think about bans.
  3. Use sources 1 and 2 as main evidence, note the bias in source 3, and avoid source 4 unless it can be verified elsewhere. (correct answer)
  4. Build his plan around the forum post and check it against the candy company article, since both offer everyday opinions rather than confusing scientific language.
Explanation: The best plan leans on the peer-reviewed study and the government health page as main evidence, because both come from qualified authors, are recent, and have no product to sell. It also handles the weaker sources wisely: it acknowledges that the candy company article is biased (the company profits from selling junk food) and it sets aside the anonymous forum post unless another reliable source confirms it. That is exactly what assessing credibility means—weighing author expertise, date, and possible bias. Treating all four sources as equally trustworthy is wrong because credibility is not equal; an anonymous post and a company ad do not deserve the same weight as expert research. Relying mainly on the candy company article and forum post fails because strong opinions are not the same as reliable evidence, and a company arguing for its own products is clearly biased. Building the plan around the forum post and checking it against the candy company article is also flawed, since two low-credibility sources cannot verify each other, and "everyday opinions" are not more accurate than expert findings. Only the plan that ranks sources by credibility uses information responsibly.

Question 11

Jamal is researching: "Do later school start times help middle school students?" He writes this sentence in his draft:

"Adolescents experience a natural shift in their sleep cycle that makes it difficult to fall asleep early."

He took the idea from a 2022 American Academy of Pediatrics (AAP) policy statement, but he did not add any citation.

What is the BEST revision to avoid plagiarism and follow standard citation format (APA)?

  1. Leave the sentence as it is because this is widely known information that most people already accept as common knowledge.
  2. Add an in-text citation after the sentence, such as (American Academy of Pediatrics, 2022). (correct answer)
  3. Put the whole sentence in quotation marks, since showing that the words are borrowed makes an extra citation unnecessary.
  4. Reword the sentence using different synonyms and sentence structure so that it now counts as his own paraphrase.
Explanation: Jamal borrowed a specific idea from a source, so he must give credit even though the words are not a direct quote. In APA style, that means placing an in-text citation with the author and year right after the sentence, like (American Academy of Pediatrics, 2022). This choice does exactly that. Leaving the sentence unchanged treats the idea as common knowledge, but a specific finding from a 2022 policy statement is not something everyone already knows, so it still needs a citation. Putting the sentence in quotation marks may show the words are borrowed, but quotation marks alone are not enough—you still have to tell the reader where the quote came from. Rewording with synonyms and new sentence structure creates a paraphrase, yet a paraphrase of someone else's idea still requires a citation; changing the wording does not make the idea yours. Only adding the citation both avoids plagiarism and follows APA format.

Question 12

Amir is writing a paragraph about energy drinks and teens. He uses a sentence from a book and includes an in-text citation:

Text in Amir's draft: According to the National Academies, "caffeine can cause sleep problems and anxiety in some children and adolescents" (National Academies of Sciences, Engineering, and Medicine, 2020, p. 112).

Which statement BEST describes Amir's use of source information?

  1. He used a direct quote correctly with quotation marks and an APA-style in-text citation. (correct answer)
  2. He should paraphrase the sentence instead, because directly quoting a source counts as plagiarism even when it is cited.
  3. He should drop the quotation marks now that the citation is present, since the citation already signals the words are borrowed.
  4. He should delete the page number from the citation, because page numbers belong only in a works cited list, not in the text.
Explanation: The best answer notes that Amir did everything right: he put the source's exact words inside quotation marks and followed them with a complete APA in-text citation naming the author (National Academies), the year (2020), and the page (p. 112). That is exactly how you use a direct quote. The choice claiming he must paraphrase to avoid plagiarism is wrong—direct quoting is allowed and honest as long as you use quotation marks and cite the source, which Amir did. The choice telling him to drop the quotation marks is wrong because a citation alone is not enough; quotation marks are required to show the words are copied exactly, not reworded. The choice telling him to delete the page number is wrong because in APA a direct quote should include the page number right in the text so readers can find the exact words. Since only one option describes correct source use, that is the answer.

Question 13

Maya is researching how wildfires affect air quality. She wants to paraphrase information from a state health department page (2021) that says smoke can irritate lungs and make asthma worse.

Which sentence is the best paraphrase that avoids plagiarism AND cites the source?

  1. Wildfire smoke can irritate the lungs and worsen asthma, according to a state health department web page (California Department of Public Health, 2021). (correct answer)
  2. Wildfire smoke can irritate the lungs and make asthma worse.
  3. "Smoke can irritate lungs and make asthma worse" (California Department of Public Health).
  4. The California Department of Public Health says smoke can irritate lungs and make asthma worse, so I don't need to cite it.
Explanation: This question tests W.7.8—gather information from multiple sources, assess credibility/accuracy, quote/paraphrase avoiding plagiarism, follow citation format. Research requires: MULTIPLE CREDIBLE SOURCES (3-5 different: books, databases, credible websites, primary sources; assess credibility: author credentials/expert?, reputable publisher?, current date for current topics?, purpose/bias considered?—avoid unreliable: Wikipedia only, random blogs, no author, out-of-date, clearly biased unacknowledged), PROPER USE (quote: exact words in quotation marks with citation, paraphrase: own words with citation—change structure not just synonyms, summarize: main ideas with attribution—integrate smoothly), AVOID PLAGIARISM (cite all sources, don't copy word-for-word without quotes, put into own words when paraphrasing, attribute ideas), STANDARD CITATION (format taught: author, title, publication info, date, proper punctuation, parenthetical in text, works cited page). Maya needs to paraphrase information about wildfire smoke effects while properly citing the source. Option A successfully paraphrases by using different wording ("irritate the lungs and worsen asthma" instead of exact original) AND includes proper citation with source name and year in parentheses. Option B paraphrases but lacks any citation; option C uses quotation marks incorrectly for a paraphrase and has incomplete citation; option D mentions the source but explicitly refuses to cite it. Students must learn that paraphrasing requires BOTH rewording the information in their own words AND citing the source. Teaching effective paraphrasing means demonstrating how to change sentence structure and vocabulary while preserving meaning, always followed by proper citation format including source name and date to give credit for the information.

Question 14

Sofia is writing about the history of vaccines. She copies this from a website into her report without quotation marks:

Original from HistoryOfMedicineFacts.net (no author listed): "Edward Jenner observed that milkmaids who caught cowpox seemed protected from smallpox."

Sofia's sentence: Edward Jenner observed that milkmaids who caught cowpox seemed protected from smallpox.

What problem is shown in Sofia's writing?

  1. There is no problem, because she reworded the idea into her own sentence and added the fact to her own report about vaccines.
  2. It is direct copying (plagiarism) because she used the exact wording without quotation marks and a citation naming the source. (correct answer)
  3. It is only a citation-format issue, because the facts are accurate and she simply forgot to list the website on her works-cited page.
  4. It is acceptable paraphrasing, because she kept the historical facts the same while presenting them smoothly inside her own report.
Explanation: Sofia copied the website's sentence word for word but presented it as her own writing. Because the wording is exactly the same, this is plagiarism: using someone else's exact words requires both quotation marks and a citation naming the source. That is why the choice about direct copying is correct. The choice saying there is no problem is wrong because she did NOT reword anything—her sentence matches the original letter for letter, so it is not her own wording. The choice calling it only a citation-format issue is wrong because the accuracy of the facts and a missing works-cited entry are not the real problem; even a perfect citation would still need quotation marks around exact wording. The choice calling it acceptable paraphrasing is wrong because paraphrasing means restating an idea in your own sentence structure and words—Sofia changed nothing, so no paraphrasing happened. Remember: to paraphrase, change the wording AND cite the source; to quote, use quotation marks AND cite the source. Copying exact words without either is always plagiarism, no matter how short the passage is or what the website's address ends in.

Question 15

You are researching: Should schools start later to improve middle school student sleep?

A student writes this sentence in the draft:
"Teen brains naturally fall asleep later, so early school start times reduce total sleep and can harm learning."

The student got this idea from a 2022 article on the American Academy of Pediatrics (AAP) website but did not use quotation marks or a citation.

Does this count as plagiarism?

A) No, because it is common knowledge that teens like to stay up late
B) Yes, because the student used an idea from a source without giving credit
C) No, because the student changed the wording and did not copy exact sentences
D) Yes, but only if the student also copied pictures or graphs from the AAP website

  1. No, because it is common knowledge that teens like to stay up late
  2. Yes, because the student used an idea from a source without giving credit (correct answer)
  3. No, because the student changed the wording and did not copy exact sentences
  4. Yes, but only if the student also copied pictures or graphs from the AAP website
Explanation: This question tests gathering relevant information from multiple print and digital sources using effective search terms, assessing source credibility and accuracy (authority, publication type, currency, bias), quoting or paraphrasing data and conclusions properly (with citation), avoiding plagiarism (attributing all source material), and following standard citation format (MLA or APA simplified for 8th grade). Choice B correctly identifies this as plagiarism because the student used specific information from a source (the AAP article about teen sleep patterns) without providing any attribution, even though the wording was changed. Plagiarism includes using someone else's ideas, not just their exact words, without giving credit through proper citation. The fact that the student paraphrased rather than quoted directly does not excuse the lack of attribution - both direct quotes and paraphrases require citations to avoid plagiarism. The correct answer recognizes that using source material without credit violates academic integrity, regardless of whether the words were changed. The incorrect options reflect common misconceptions: choice A wrongly assumes general topics don't need citations, choice C mistakenly believes paraphrasing eliminates the need for attribution, and choice D incorrectly limits plagiarism to visual materials. To avoid plagiarism, students must cite all information that comes from sources, whether quoted directly or paraphrased, unless it is truly common knowledge (facts known by most people without needing to look them up).

Question 16

You are researching the benefits of recycling aluminum. A website from the U.S. Environmental Protection Agency (EPA) states: "Recycling aluminum saves more than 90% of the energy required to make new aluminum from raw materials."

A student writes in their draft:
"Recycling aluminum saves more than 90% of the energy required to make new aluminum from raw materials."

There are NO quotation marks and NO citation.

Does this count as plagiarism?

A) No, because facts are common knowledge and never need to be attributed to a source
B) No, because the student typed the sentence themselves instead of copying and pasting it
C) Yes, because the student used the exact wording without quotation marks or citation
D) Yes, but only if the EPA website charges a fee to read its published content

  1. No, because facts are common knowledge and never need to be attributed to a source
  2. No, because the student typed the sentence themselves instead of copying and pasting it
  3. Yes, because the student used the exact wording without quotation marks or citation (correct answer)
  4. Yes, but only if the EPA website charges a fee to read its published content
Explanation: Plagiarism happens when you present someone else's exact words as your own without quotation marks and a citation. The student copied the EPA's sentence word for word but added no quotation marks and no source, so this counts as plagiarism — that is why the choice pointing to the exact wording without quotation marks or citation is correct. The option claiming facts are common knowledge that never need attribution is wrong: even true facts must be attributed when you borrow the source's exact phrasing. The option about typing the sentence instead of copying and pasting is wrong because plagiarism depends on whose words they are, not on how the text got onto the page. The option that ties plagiarism to whether the website charges a fee is wrong because attribution rules apply to all sources, free or paid. To do this correctly, either put the sentence in quotation marks with an EPA citation, or paraphrase it in your own words and still cite the EPA.

Question 17

You are researching: "How does climate change affect the frequency and intensity of heat waves in the United States?" You find four possible sources.

Which source is MOST credible to use as a main source for scientific evidence?

A) NASA Climate website article, updated 2024, credited to NASA scientists (.gov) B) Personal blog post (no author credentials) claiming "heat waves are a hoax," posted 2017 C) Social media thread summarizing a TV segment, no links to data, posted 2025 D) Advertisement from an air conditioner company explaining why summers feel hotter, no citations

  1. A) NASA Climate website article, updated 2024, credited to NASA scientists (.gov) (correct answer)
  2. B) Personal blog post (no author credentials) claiming "heat waves are a hoax," posted 2017
  3. C) Social media thread summarizing a TV segment, no links to data, posted 2025
  4. D) Advertisement from an air conditioner company explaining why summers feel hotter, no citations
Explanation: This question tests gathering relevant information from multiple print and digital sources using effective search terms, assessing source credibility and accuracy (authority, publication type, currency, bias), quoting or paraphrasing data and conclusions properly (with citation), avoiding plagiarism (attributing all source material), and following standard citation format (MLA or APA simplified for 8th grade). When researching climate change and heat waves, you need scientific evidence from credible sources with expertise, recent data, and no commercial bias - the NASA Climate website (.gov domain) is written by climate scientists, updated in 2024, and provides government-verified scientific data. For example, a NASA article would include peer-reviewed research, temperature data, and citations to scientific studies, making it ideal for academic research on climate topics. Option A is correct because NASA is a government scientific agency with climate experts, the .gov domain indicates official government information, and the 2024 update ensures current data. The incorrect options fail credibility tests: B is a personal blog with no credentials and outdated information plus bias ("hoax"), C is social media without original data or citations, and D is a commercial source with potential bias to sell products and no scientific citations. When gathering information, always check the source's authority (who wrote it), currency (when published/updated), accuracy (verifiable data), and purpose (why it was created) to determine credibility.

Question 18

You are researching: What are the health effects of vaping on teenagers? You gathered sources from print and digital places:

  1. Print book (library): "Teen Health Today" (2021), written by a pediatrician, published by an educational publisher
  2. Digital: CDC webpage on e-cigarettes (cdc.gov), updated 2024
  3. Digital: Peer-reviewed journal article (2020) about nicotine addiction in adolescents
  4. Digital: Influencer video (no sources listed) claiming vaping is "just water vapor"

Which research plan shows the best credibility assessment and use of sources?

  1. Use the influencer video as the main source because it is the most recent and easiest to understand, use the CDC webpage for background definitions, and skip the journal article since its technical language makes it too hard to quote accurately
  2. Use the CDC webpage and the peer-reviewed journal article as primary evidence, use the print book for background definitions, and mention the influencer video only as an example of misinformation (correct answer)
  3. Use only the print book because online sources can be edited by anyone, use the influencer video for a modern student perspective, and avoid the CDC webpage and journal article since digital sources cannot be trusted
  4. Use all four sources equally as primary evidence because gathering the largest number of sources automatically makes a report more accurate, and treat the influencer video as reliable as the journal article
Explanation: The strongest plan builds its main evidence on the sources with real authority: the CDC webpage, which is a government health agency updated in 2024, and the peer-reviewed journal article, which experts checked before publication. It uses the pediatrician-authored book for background and correctly treats the influencer video as an example of misinformation rather than throwing it away, since a claim with no listed sources is itself worth discussing. The plan that leans on the influencer video is wrong because "recent" and "easy" do not equal credible, and dropping the journal article for being technical discards your best evidence. The plan that uses only the print book is wrong because rejecting all digital sources is a misconception—credible digital sources like the CDC and peer-reviewed research exist. The plan that uses everything equally is wrong because the number of sources does not create accuracy; treating an unsourced video as equal to peer-reviewed research ignores credibility entirely. Good research means judging each source individually and using the most authoritative ones for your main claims.

Question 19

You are researching: How effective are residential solar panels at reducing a household's electricity costs? Your first search, "energy," gives millions of unrelated results. Which set of search terms is MOST likely to find relevant, focused sources?

  1. "solar energy" OR (renewable AND power) OR homes OR savings OR bills OR utility (general topic terms combined broadly)
  2. "solar panel" AND residential AND ("cost savings" OR "electricity bill") AND efficiency (correct answer)
  3. "green technology" AND environment AND (climate OR sustainability) AND benefits (focused on ecological impact terms)
  4. solar panel residential 2013 2014 2015 2016 2017 2018 2019 2020 2021 2022 2023 2024 comparison calculator government database reviews
Explanation: The best search combines the exact phrase "solar panel" with residential and links cost savings or electricity bill and efficiency using AND and OR operators. This targets every key idea in your research question at once, so results focus tightly on home solar and money saved. The choice stacking broad topic words like renewable, homes, savings, and utility with OR keeps the search too general—OR widens results instead of narrowing them, so you would still get millions of loose hits. The choice built around green technology, environment, climate, and sustainability is well-structured but aims at the wrong topic: it searches ecological impact, not the household electricity costs your question asks about. The choice piling up many years, comparison, calculator, and database has relevant words but no quotation marks or operators to connect ideas, so a search engine reads it as a jumble and returns confusing or empty results. Strong search terms name the specific concepts from your question and use operators correctly to combine them—matching the topic AND joining the ideas both matter.

Question 20

You are writing a report on plastic pollution in oceans. You used a webpage from the National Oceanic and Atmospheric Administration (NOAA).

Source details:

Which is the best simplified MLA Works Cited entry for an 8th-grade paper?

  1. NOAA. "Marine Debris: Plastics." noaa.gov. 2023. https://www.noaa.gov/education/resource-collections/ocean-coasts/marine-debris.
  2. National Oceanic and Atmospheric Administration. "Marine Debris: Plastics." NOAA, 2023, https://www.noaa.gov/education/resource-collections/ocean-coasts/marine-debris. (correct answer)
  3. "Marine Debris: Plastics." National Oceanic and Atmospheric Administration. 2023. https://www.noaa.gov/education/resource-collections/ocean-coasts/marine-debris.
  4. National Oceanic and Atmospheric Administration (2023). Marine Debris: Plastics. Retrieved from https://www.noaa.gov/education/resource-collections/ocean-coasts/marine-debris.
Explanation: The best entry names the full organization first, puts the page title in quotation marks, gives the website name, then the year, then the URL, using commas to link the pieces and a period at the end: "National Oceanic and Atmospheric Administration. 'Marine Debris: Plastics.' NOAA, 2023, https://…marine-debris." The commas and order match simplified MLA style. The entry starting with "NOAA." uses only the abbreviation instead of the full organization name, and it separates every element with periods instead of MLA's commas. The entry that begins with the title in quotation marks leaves the organization out of the author position, so the source is no longer alphabetized or credited correctly. The last entry uses APA style—putting the year in parentheses after the author, dropping the quotation marks around the title, and adding "Retrieved from"—which are not MLA conventions. Because all four now end with a period, you must judge the order, punctuation, and full author name rather than any one visual clue.
