Read the passage, then answer the question.
Planting more trees near playgrounds is important because trees cool the area and improve air quality. First, trees provide shade, and shade lowers surface temperatures. The reason is that leaves block sunlight from heating up blacktop and metal equipment. For example, the City of Brookdale measured playground temperatures on a sunny day. Under a large oak tree, the ground was about 12°F cooler than the open blacktop nearby.
Second, trees help clean the air because their leaves trap tiny particles of dust and pollution. According to the U.S. Forest Service, one mature tree can absorb around 48 pounds of carbon dioxide in a year. In Brookdale, students noticed less dust on benches near the new trees after several weeks, especially on windy days.
Some people worry trees will drop leaves to clean up, but the author argues that raking can be a class job during science lessons. Therefore, planting trees near playgrounds is worth the effort.
Question: The author states that trees cool playgrounds because leaves block sunlight. What evidence supports this reason?
Under a large oak tree, the ground was about 12°F cooler than the open blacktop.
Raking can be a class job during science lessons.
One mature tree can absorb around 48 pounds of carbon dioxide in a year.
Students noticed less dust on benches near the new trees after several weeks.
Explanation
This question assesses CCSS.RI.5.8: explaining how an author uses reasons and evidence to support particular points in a text, identifying which reasons and evidence support which point(s). The author's main argument is that planting trees near playgrounds is important because trees cool the area and improve air quality. For the cooling point, the author provides the reason that leaves block sunlight from heating surfaces, and supports this with specific evidence: Brookdale's temperature measurements showing ground under oak tree was 12°F cooler. Choice A is correct because it provides concrete, measurable evidence (12°F temperature difference) that directly supports the reason about leaves blocking sunlight to cool areas. This creates the logical chain: Point (trees cool playgrounds) → Reason (leaves block sunlight) → Evidence (12°F cooler under tree). The student correctly identified evidence that proves the cooling effect. Choice B represents an error of selecting evidence that supports a different point (air quality improvement, not cooling). Students who select this may have recognized it as evidence from the passage but failed to match it to the specific reason about blocking sunlight for cooling. To help students analyze author's reasoning: Teach the argument structure hierarchy: POINT (what author claims) → REASON (why it's true) → EVIDENCE (specific proof). Use graphic organizers: create three-column chart with 'Point/Claim,' 'Reason (Why),' 'Evidence (Proof).' Annotate passages: have students underline main points, bracket reasons, and circle specific evidence, then draw arrows showing connections. Teach students to match evidence to the specific reason mentioned in the question. Common difficulties: Students often connect evidence to wrong point when author makes multiple points, especially when both cooling and air quality are discussed.

Our town should build a bike path along River Road because it would make travel safer and healthier. First, a separate path protects riders since bikes would not have to share a narrow lane with cars. For example, the River Road shoulder is only about 2 feet wide in some places, and drivers often pass quickly. According to a survey from the Parks Department, 62% of families said they avoid biking there because it feels unsafe.
Second, a bike path encourages exercise because people are more likely to ride when they feel protected. In the nearby town of Lakeview, a two-mile path opened in 2021. City data reveals that weekend bike counts rose from about 40 riders to 110 riders after the path opened. A local doctor, Dr. Chen, explained that regular biking can strengthen the heart and lungs.
Some people think a bike path would cost too much, but the author notes that Lakeview paid for its path using a state safety grant. Therefore, planning a bike path is a smart way to protect residents and support healthy habits.
Question: Why does the author include the detail that 62% of families avoid biking on River Road?
To support the point that River Road feels unsafe for many riders.
To argue that grants should replace all town taxes.
To show that Lakeview’s bike path is exactly two miles long.
To prove that biking always strengthens the heart and lungs.
Explanation
This question assesses CCSS.RI.5.8: explaining how an author uses reasons and evidence to support particular points in a text, identifying which reasons and evidence support which point(s). The author's main argument is that the town should build a bike path because it would make travel safer and healthier. For the safety point, the author provides the reason that bikes wouldn't have to share narrow lanes with cars, and supports this with evidence including the 62% survey statistic. Choice A is correct because it accurately identifies that the 62% statistic serves as evidence supporting the point about River Road feeling unsafe for riders. This creates the logical chain: Point (bike path makes travel safer) → Reason (bikes won't share narrow lanes) → Evidence (62% avoid biking because it feels unsafe). The student correctly traced how this specific evidence supports the safety concern. Choice B represents an error of connecting the evidence to the wrong point (health benefits rather than safety). Students who select this may have seen that the passage mentions health but didn't trace which evidence supports which specific point. To help students analyze author's reasoning: Teach the argument structure hierarchy: POINT (what author claims) → REASON (why it's true) → EVIDENCE (specific proof). Use graphic organizers: create three-column chart with 'Point/Claim,' 'Reason (Why),' 'Evidence (Proof).' Teach signal words: Evidence often follows 'according to,' 'survey shows,' or includes specific numbers and percentages. Model think-aloud: 'The author's point is bike paths improve safety. Why? Because bikes won't share narrow lanes. What proof? 62% of families avoid biking there.' Common difficulties: Students often connect evidence to wrong point when author makes multiple points, especially when both safety and health are discussed.
Read the passage, then answer the question.
Students should have a short “quiet reading” time after lunch because it improves focus for afternoon classes. First, reading quietly helps brains settle down since lunch and recess can be loud and busy. For example, Ms. Rivera tried a 10-minute reading time with her fifth graders for two weeks. She counted how many times she had to stop lessons to remind students to listen. The number dropped from about 12 reminders per day to 7.
Second, quiet reading builds vocabulary because students meet new words in books. Research indicates that students who read often learn word meanings faster than students who rarely read. In Ms. Rivera’s class, students kept a list of new words they found. By the end of the two weeks, most students had written 15–20 new words and shared them with partners.
Some students might say they would rather talk with friends, but the author explains that the reading time is short and still leaves time for socializing later. Therefore, a brief reading routine can help students learn more in the afternoon.
Question: What evidence does the author provide to support the reason that quiet reading improves focus after lunch?
Most students wrote 15–20 new words in their lists.
The author says students can still socialize later in the day.
Ms. Rivera counted fewer daily reminders, dropping from about 12 to 7.
Research indicates that students who read often learn word meanings faster.
Explanation
This question assesses CCSS.RI.5.8: explaining how an author uses reasons and evidence to support particular points in a text, identifying which reasons and evidence support which point(s). The author's main argument is that students should have quiet reading time after lunch because it improves focus for afternoon classes. To support this point about improved focus, the author provides the reason that reading helps brains settle down after loud activities, and offers specific evidence: Ms. Rivera's data showing reminders dropped from 12 to 7 per day. Choice B is correct because it provides concrete, measurable evidence (reminders dropping from 12 to 7) that directly supports the specific point about quiet reading improving focus. This creates the logical chain: Point (reading improves afternoon focus) → Reason (helps brains settle down) → Evidence (reminders decreased from 12 to 7). Choice C represents an error of selecting evidence that supports a different point (vocabulary building, not focus improvement). Students who select this may have recognized it as evidence from the passage but failed to match it to the specific point asked about regarding focus. To help students analyze author's reasoning: Teach the argument structure hierarchy: POINT (what author claims) → REASON (why it's true) → EVIDENCE (specific proof). Use graphic organizers: create three-column chart with 'Point/Claim,' 'Reason (Why),' 'Evidence (Proof).' Annotate passages: have students underline main points, bracket reasons, and circle specific evidence, then draw arrows showing connections. Practice tracing: Give students a piece of evidence and ask which reason it supports. Common difficulties: Students often connect evidence to wrong point when author makes multiple points, as this passage does with both focus improvement and vocabulary building.
Read the passage, then answer the question.
Schools should teach basic first aid in fifth grade because it helps students respond calmly in small emergencies. First, learning first aid builds confidence since students practice what to do step by step. For example, in a program at Pine Hill School, the nurse taught students how to clean a small cut and apply a bandage. After the lesson, students took a short quiz. Class results improved from an average of 55% before the lesson to 88% after.
Second, first aid lessons can prevent problems from getting worse because students learn when to ask an adult for help. The nurse explained, “Knowing when to get help is as important as knowing how to use a bandage.” During recess the next week, a student named Sofia saw a classmate with a scraped knee. Sofia walked her to the office instead of ignoring it.
Some people think first aid is only for adults, but the author explains that the lessons focus on simple, safe actions. Therefore, teaching first aid is a useful way to build responsibility.
Question: Which statement best explains how the author supports the claim that first aid lessons build confidence?
The author explains that raking leaves can be a class job during science.
The author argues that first aid is only for adults, so students should not learn it.
The author gives quiz data showing scores rose from 55% to 88% after practice.
The author lists different kinds of books, like mysteries and biographies.
Explanation
This question assesses CCSS.RI.5.8: explaining how an author uses reasons and evidence to support particular points in a text, identifying which reasons and evidence support which point(s). The author's main argument is that schools should teach basic first aid because it helps students respond calmly in emergencies. To support the claim that first aid lessons build confidence, the author provides the reason that students practice step by step, and offers specific evidence: quiz scores improving from 55% to 88% after the lesson. Choice B is correct because it accurately describes how the author uses concrete data (quiz scores rising from 55% to 88%) to support the confidence-building claim. This creates the logical chain: Point (first aid builds confidence) → Reason (students practice step by step) → Evidence (quiz scores improved from 55% to 88%). The data demonstrates that students gained confidence through improved performance. Choice A represents a misreading error—the passage actually explains that lessons focus on simple actions, not that first aid is only for adults. Students who select this have misunderstood the author's counterargument section. To help students analyze author's reasoning: Teach the argument structure hierarchy: POINT (what author claims) → REASON (why it's true) → EVIDENCE (specific proof). Use graphic organizers: create three-column chart with 'Point/Claim,' 'Reason (Why),' 'Evidence (Proof).' Teach students to distinguish between the author's actual claims and what the author mentions as others' concerns. Model careful reading of counterargument sections. Common difficulties: Students often misread counterarguments as the author's own claims, or select evidence from unrelated passages when they recognize familiar content.
Read the passage, then answer the question.
Many schools should start a compost bin in the cafeteria because it reduces trash and helps gardens. First, composting cuts down on how much food goes into landfills. The reason is that fruit peels, bread crusts, and leftovers can turn into soil instead of garbage. For example, at Maple Grove Elementary, students weighed cafeteria waste for one week. Data showed that about 18 pounds of fruit and vegetable scraps were thrown away each day. After the school began composting, the trash bags from lunch dropped from 10 bags a day to 7.
Second, compost helps school gardens grow better plants because it adds nutrients to the soil. According to the National Gardening Association, compost improves soil so it holds water longer. This means plants can stay healthy even on hot days. In Maple Grove’s garden, the science club mixed compost into two raised beds. Those beds grew 25% more tomatoes than beds that used only regular dirt.
Some students worry compost will smell bad, but the author explains that a covered bin and dry leaves prevent odors. Therefore, composting is a practical program that saves space in trash cans and supports learning outdoors.
Question: Which evidence from the passage best supports the author’s point that composting reduces cafeteria trash?
Trash bags from lunch dropped from 10 bags a day to 7 after composting began.
A covered bin and dry leaves can prevent odors.
The science club mixed compost into two raised beds.
Compost improves soil so it holds water longer, according to the National Gardening Association.
Explanation
This question assesses CCSS.RI.5.8: explaining how an author uses reasons and evidence to support particular points in a text, identifying which reasons and evidence support which point(s). The author's main argument is that schools should start compost bins because they reduce trash and help gardens. To support the first point about reducing trash, the author provides the reason that food scraps can turn into soil instead of garbage, and offers specific evidence: Maple Grove Elementary's data showing trash bags dropped from 10 to 7 per day after composting began. Choice B is correct because it provides concrete, measurable evidence (trash bags dropping from 10 to 7) that directly supports the specific point about composting reducing cafeteria trash. This creates the logical chain: Point (composting reduces trash) → Reason (food becomes soil not garbage) → Evidence (trash bags decreased from 10 to 7). Choice A represents a common error of selecting evidence that supports a different point (helping gardens, not reducing trash). Students who select this may have recognized it as evidence from the passage but failed to match it to the specific point asked about in the question. To help students analyze author's reasoning: Teach the argument structure hierarchy: POINT (what author claims) → REASON (why it's true) → EVIDENCE (specific proof). Use graphic organizers: create three-column chart with 'Point/Claim,' 'Reason (Why),' 'Evidence (Proof).' Annotate passages: have students underline main points, bracket reasons, and circle specific evidence, then draw arrows showing connections. Practice tracing: Give students a piece of evidence and ask which reason it supports; give a reason and ask which point it supports. Common difficulties: Students often connect evidence to wrong point when author makes multiple points, as this passage does with both trash reduction and garden benefits.

A class nature journal is a powerful science tool because it helps students notice details and ask better questions. First, journaling improves observation since students slow down and record what they actually see. For example, during a pond walk, students wrote down colors, shapes, and movements. Marcus first wrote, “I saw bugs.” After a week of journaling, he wrote, “I saw three water striders making circles on the surface.” This shows his observations became more specific.
Second, journals support questions because students can look back and compare notes over time. In one class, students checked their entries from September and November. They noticed fewer butterflies in November and asked why. The teacher used that question to start a lesson about migration and temperature changes.
Some students think journaling is extra work, but the author argues that quick sketches and short sentences are enough. Therefore, nature journals make science learning clearer and more meaningful.
Question: Why does the author include Marcus’s change from “I saw bugs” to “I saw three water striders making circles”?
To support the point that journaling improves observation by making details more specific.
To prove that butterflies always migrate in November.
To argue that students should only study ponds in science class.
To show that sketches must be long and detailed to count.
Explanation
This question assesses CCSS.RI.5.8: explaining how an author uses reasons and evidence to support particular points in a text, identifying which reasons and evidence support which point(s). The author's main argument is that nature journals are powerful science tools because they help students notice details and ask better questions. To support the point about improving observation by making details more specific, the author provides Marcus's example showing progression from vague to specific observations. Choice A is correct because it accurately identifies that Marcus's change from general 'bugs' to specific 'three water striders making circles' serves as evidence supporting the point that journaling improves observation through increased specificity. This creates the logical chain: Point (journals improve observation) → Reason (students record what they actually see) → Evidence (Marcus's observations became more specific). Choice B represents an error of inventing a claim not made in the passage—the author never claims butterflies always migrate in November. Students who select this have misread or misremembered the passage content about November observations. To help students analyze author's reasoning: Teach the argument structure hierarchy: POINT (what author claims) → REASON (why it's true) → EVIDENCE (specific proof). Use graphic organizers: create three-column chart with 'Point/Claim,' 'Reason (Why),' 'Evidence (Proof).' Teach students to identify before/after examples as evidence of improvement or change. Model recognizing when evidence shows progression: 'First he wrote vaguely, then specifically—this proves observation improved.' Common difficulties: Students often select answers that sound related to the topic but don't actually appear in the passage or don't match the specific point being supported.
Read the passage, then answer the question.
A school library should keep a “student recommendation shelf” because it helps more kids find books they enjoy. First, recommendations work since students often trust classmates who like the same stories. For example, when Westfield School added a shelf with student note cards, librarian Ms. Keisha Brown tracked checkouts. Data showed that books on the shelf were checked out 30% more often than similar books on other shelves.
Second, the shelf supports reading variety because students suggest many types of books. In one month, the shelf included mysteries, biographies, sports books, and graphic novels. A fifth grader named Amir wrote, “I tried a biography for the first time because my friend recommended it.” This shows that recommendations can push students to try something new.
Some people think students will only recommend popular series, but the author explains that the librarian can limit repeats and ask for different genres. Therefore, a student recommendation shelf is a simple way to increase reading interest.
Question: Which reason does the author give to support the point that a student recommendation shelf helps more kids find books they enjoy?
Students often trust classmates who like the same kinds of stories.
Books on the shelf were checked out 30% more often than similar books.
The shelf included mysteries, biographies, sports books, and graphic novels.
The librarian can limit repeats and ask for different genres.
Explanation
This question assesses CCSS.RI.5.8: explaining how an author uses reasons and evidence to support particular points in a text, identifying which reasons and evidence support which point(s). The author's main argument is that libraries should keep student recommendation shelves because they help more kids find books they enjoy. To support this point, the author provides the reason that students often trust classmates who like the same stories, and offers evidence including checkout data showing 30% increase. Choice A is correct because it identifies the reason (students trust classmates with similar tastes) that explains WHY recommendation shelves help kids find enjoyable books. This represents the 'why' in the logical chain: Point (shelves help kids find books) → Reason (students trust peers) → Evidence (30% more checkouts). Choice C represents a common error of confusing evidence with reason. While the 30% checkout increase is evidence supporting the point, it's not the reason WHY the shelves work—that reason is peer trust. Students who select this may not distinguish between reasons (explanations of why) and evidence (specific proof). To help students analyze author's reasoning: Teach the argument structure hierarchy: POINT (what author claims) → REASON (why it's true) → EVIDENCE (specific proof). Use graphic organizers: create three-column chart with 'Point/Claim,' 'Reason (Why),' 'Evidence (Proof).' Teach signal words: Reasons often follow 'because,' 'since,' while evidence includes specific numbers, data, or examples. Model think-aloud: 'The point is shelves help kids find books. Why? Because students trust peers. What's the proof? 30% more checkouts.' Common difficulties: Students often confuse reasons (explanations of why) with evidence (specific proof), selecting data when asked for the underlying reason.

Our community should add more streetlights near the park because better lighting makes walking safer. First, lights help people see obstacles since shadows can hide cracks in sidewalks and low branches. For example, the Parks Office counted reports of small falls near the park entrance. In the three months before new lights were installed, there were 9 reports. In the three months after installation, reports dropped to 3.
Second, lighting can discourage rule-breaking because people are less likely to act badly when they can be seen. A police officer, Officer Carlos Ruiz, said, “Good lighting is one of the simplest safety tools.” After the lights went up, neighbors reported fewer instances of litter left near the benches.
Some residents worry the lights will bother nearby homes, but the author explains that shielded fixtures aim light downward. Therefore, adding streetlights is a practical way to make the park more welcoming.
Question: The author explains that lights help people see obstacles. What evidence does the author use to support this reason?
Neighbors reported fewer instances of litter left near the benches.
Reports of small falls dropped from 9 to 3 after new lights were installed.
Officer Carlos Ruiz said lighting is one of the simplest safety tools.
Shielded fixtures aim light downward to avoid bothering homes.
Explanation
This question assesses CCSS.RI.5.8: explaining how an author uses reasons and evidence to support particular points in a text, identifying which reasons and evidence support which point(s). The author's main argument is that the community should add streetlights because better lighting makes walking safer. To support the reason that lights help people see obstacles, the author provides specific evidence: Parks Office data showing fall reports dropped from 9 to 3 after new lights were installed. Choice C is correct because it provides concrete, measurable evidence (fall reports dropping from 9 to 3) that directly supports the reason about lights helping people see obstacles. This creates the logical chain: Point (lighting makes walking safer) → Reason (helps see obstacles) → Evidence (falls decreased from 9 to 3). The decrease in falls proves that better visibility of obstacles prevents accidents. Choice A represents an error of selecting evidence that supports a different reason (discouraging rule-breaking, not seeing obstacles). Students who select this may have recognized it as evidence but failed to match it to the specific reason about obstacle visibility. To help students analyze author's reasoning: Teach the argument structure hierarchy: POINT (what author claims) → REASON (why it's true) → EVIDENCE (specific proof). Use graphic organizers: create three-column chart with 'Point/Claim,' 'Reason (Why),' 'Evidence (Proof).' Teach students to match evidence to the specific reason—obstacle visibility needs evidence about seeing/falling, not about behavior. Model think-aloud: 'The reason is lights help see obstacles. What evidence proves this? Fewer falls shows people could see better.' Common difficulties: Students often select any safety-related evidence without checking if it matches the specific safety reason mentioned.

Bringing reusable water bottles to school is a smart idea because it reduces plastic waste and keeps students hydrated. First, reusable bottles cut down on trash since fewer single-use bottles get thrown away. For example, the student council at East Ridge counted plastic bottles in the cafeteria trash for five days. They found about 95 bottles per day. After a “Bring Your Bottle” challenge, the count fell to about 35 bottles per day.
Second, having water nearby helps students drink more because they do not have to wait for a fountain. A teacher, Ms. Yuki Tanaka, tracked how often students asked to leave class for water. During the challenge, requests dropped from 14 per day to 6. Students said they took quick sips during independent work time.
Some people worry reusable bottles are hard to clean, but the author notes that hot, soapy water and a bottle brush work well. Therefore, reusable bottles help both the environment and learning.
Question: Which detail from the passage best supports the author’s point that reusable bottles reduce plastic waste?
Requests to leave class for water dropped from 14 per day to 6.
Hot, soapy water and a bottle brush work well for cleaning bottles.
Students said they took quick sips during independent work time.
Plastic bottles in the trash fell from about 95 per day to about 35 per day.
Explanation
This question assesses CCSS.RI.5.8: explaining how an author uses reasons and evidence to support particular points in a text, identifying which reasons and evidence support which point(s). The author's main argument is that bringing reusable water bottles is smart because it reduces plastic waste and keeps students hydrated. To support the point about reducing plastic waste, the author provides the reason that fewer single-use bottles get thrown away, and offers specific evidence: East Ridge's bottle count dropping from 95 to 35 per day. Choice C is correct because it provides concrete, measurable evidence (plastic bottles in trash falling from 95 to 35 daily) that directly supports the specific point about reusable bottles reducing plastic waste. This creates the logical chain: Point (reusable bottles reduce waste) → Reason (fewer single-use bottles thrown away) → Evidence (bottle count dropped from 95 to 35). Choice A represents an error of selecting evidence that supports a different point (hydration/convenience, not waste reduction). Students who select this may have recognized it as evidence but failed to match it to the waste reduction point. To help students analyze author's reasoning: Teach the argument structure hierarchy: POINT (what author claims) → REASON (why it's true) → EVIDENCE (specific proof). Use graphic organizers: create three-column chart with 'Point/Claim,' 'Reason (Why),' 'Evidence (Proof).' Teach students to match evidence type to claim type—waste claims need waste evidence, not convenience evidence. Practice identifying which evidence supports which specific point when passages make multiple arguments. Common difficulties: Students often connect evidence to wrong point when author makes multiple points about both environmental and personal benefits.
Read the passage.
Many students feel sleepy during first period, so our school should start classes 15 minutes later. This change would not make school “easier.” Instead, it would help students learn better because their brains would be more awake.
First, later start times improve attention because most kids need about 9–11 hours of sleep. According to the American Academy of Pediatrics, middle schools that start later often see better alertness. For example, a nearby district in Milltown moved the bell from 7:45 to 8:15, and teachers reported fewer students putting their heads down.
Second, a later start can reduce tardies because buses and families would have a slightly larger morning window. Data from our school’s office shows that on rainy days, tardies rise from about 12 students to about 28 students. A 15-minute shift would give families more time when traffic is slow.
Some people worry sports would end later, but practices can begin right after school as usual. Therefore, starting 15 minutes later is a smart change because it supports learning and helps students arrive on time.
Question: Which evidence from the passage best supports the author’s reason that a later start could reduce tardies?
The author says the change would help students learn better.
The author claims practices can begin right after school as usual.
The office data shows tardies rise from about 12 to about 28 students on rainy days.
The American Academy of Pediatrics says kids need 9–11 hours of sleep.
Explanation
This question assesses CCSS.RI.5.8: explaining how an author uses reasons and evidence to support particular points in a text, identifying which reasons and evidence support which point(s). The author's main argument is that school should start 15 minutes later. To support this, the author provides two key points: (1) later start times improve attention because kids need more sleep, and (2) later start can reduce tardies because families would have more time in the morning. For the second point about reducing tardies, the author explains the reason (buses and families would have a larger morning window) and provides evidence with specific data about rainy days. Choice B is correct because it accurately identifies the specific evidence—'office data shows tardies rise from about 12 to about 28 students on rainy days'—that supports the point about reducing tardies. This evidence provides concrete proof showing how morning time pressure affects tardiness rates, creating the logical chain: Point (reduce tardies) → Reason (more morning time helps) → Evidence (tardy data on rainy days). Choice C represents a wrong point connection error. Students who select this may have connected evidence about sleep needs to the wrong point—this evidence supports the attention/alertness point, not the tardiness point. To help students analyze author's reasoning: Teach the argument structure hierarchy: POINT (what author claims) → REASON (why it's true) → EVIDENCE (specific proof). Use graphic organizers: create three-column chart with 'Point/Claim,' 'Reason (Why),' 'Evidence (Proof).' Annotate passages: have students underline main points, bracket reasons, and circle specific evidence, then draw arrows showing connections. Teach signal words: Reasons often follow 'because,' 'since,' 'due to.' Evidence follows 'for example,' 'studies show,' 'according to,' 'research indicates,' or includes specific names, numbers, quotes. Practice tracing: Give students a piece of evidence and ask which reason it supports; give a reason and ask which point it supports. Model think-aloud: 'The author's point is reducing tardies. Why does the author think this? The reason is families need more morning time. What proof does the author give? The evidence is tardy data showing the problem on rushed mornings.'
