Question 1
A student used the transition word therefore in this sentence:
"Many students currently get only 15 minutes to eat, and long lunch lines take up most of that time; therefore, the school should extend lunch to 30 minutes."
What relationship does therefore show in this argument?
- It introduces a counterargument that disagrees with the claim.
- It shows cause-and-effect, linking the problem to the conclusion/claim. (correct answer)
- It adds another unrelated reason of equal importance.
- It introduces a specific example that proves the claim.
Explanation: This question tests using words, phrases, and clauses to create cohesion (smooth flow, connected ideas) and clarify relationships among claim(s), reasons, and evidence in argumentative writing—employing transitions making explicit how evidence supports reasons, how reasons support claim, how ideas connect. The transition "therefore" is a cause-and-effect connector that shows the logical conclusion drawn from the presented problem. In this sentence, the student first establishes the problem (only 15 minutes to eat with long lines taking up most of that time), then uses "therefore" to introduce the logical solution or claim (extend lunch to 30 minutes). This creates cohesion by making explicit the causal relationship between the identified problem and the proposed solution. Option A is incorrect because "therefore" doesn't introduce opposition. Option C is wrong because "therefore" shows logical consequence, not addition. Option D is incorrect because "therefore" introduces conclusions, not examples. Understanding how different transitions function helps writers create clear logical connections in their arguments, with "therefore," "thus," and "consequently" showing that what follows is a logical result or conclusion based on what came before.
Question 2
A student is revising an argumentative paragraph. Read the draft:
"Our school should start 30 minutes later. Many students are tired in first period. A district nearby moved its start time later and reported fewer tardies. Students also get more sleep. Teens need about 8–10 hours of sleep."
Which revision best improves cohesion by adding transitions that clearly connect the claim, reasons, and evidence?
- "Our school should start 30 minutes later. Meanwhile, many students are tired in first period. A district nearby moved its start time later and reported fewer tardies. Instead, students get more sleep, and teens need about 8–10 hours of sleep each night."
- "Our school should start 30 minutes later because many students are tired in first period. For example, a district nearby moved its start time later and reported fewer tardies. Additionally, students would get more sleep; specifically, teens need about 8–10 hours of sleep." (correct answer)
- "Our school should start 30 minutes later however many students are tired in first period. Therefore, a district nearby moved its start time later and reported fewer tardies. On the other hand, students also get more sleep, since teens need about 8–10 hours."
- "Our school should start 30 minutes later. Many students are tired in first period, also a district nearby moved its start time later. Plus, students get more sleep, and anyway teens need about 8–10 hours of sleep each night."
Explanation: The best revision uses transitions that match the true relationships among the ideas: "because" links the claim to a reason, "For example" introduces evidence, "Additionally" adds a second supporting point, and "specifically" ties the sleep evidence to that point. Each transition signals support, so the argument flows logically from claim to reason to evidence.
The version with "Meanwhile" and "Instead" chooses transitions that signal time-shifts or contrast, so it treats supporting evidence as if it were unrelated or opposing—breaking the logical connection. The version with "however" and "On the other hand" uses contrast transitions between ideas that actually agree, making it sound like each sentence disputes the one before it instead of backing it up. The version stringing together "also," "Plus," and "and anyway" only piles ideas on top of each other; these additive words never show WHY the evidence supports the reasons or how the reasons support the claim. When you revise, pick transitions that name the real relationship: cause for reasons, example for evidence, and addition for extra support that genuinely fits.
Question 3
Read this argumentative paragraph:
"Students should be allowed to carry water bottles in class. Water helps people focus. A study at a nearby middle school found that students who drank water during class reported fewer headaches. Teachers worry about spills."
Which sentence, if added after the third sentence, would best improve cohesion by acknowledging the counterargument and connecting it back to the claim?
- In fact, drinking water during class helps students focus, so allowing water bottles clearly benefits everyone in the room.
- However, this concern can be addressed by requiring bottles with secure lids, so students can stay hydrated without making a mess. (correct answer)
- Additionally, the study proved that headaches are unpleasant, which shows why students really need to bring water to class.
- In conclusion, spills matter to teachers, so students should probably just keep their water bottles at home instead.
Explanation: The paragraph raises a counterargument in its last sentence—teachers worry about spills. The best addition names that worry and answers it, then ties back to the original claim. The sentence beginning "However" does exactly this: it acknowledges the spill concern, offers a workable fix (secure lids), and reconnects to the goal of letting students stay hydrated. That is what cohesion between claim, evidence, and counterargument looks like.
The sentence starting "In fact" only restates support for the claim; it never mentions the spill worry, so it ignores the counterargument entirely. The sentence starting "Additionally" also skips the counterargument and, worse, overstates the evidence by saying the study "proved" something about headaches being unpleasant. The sentence beginning "In conclusion" does mention spills but then abandons the writer's claim, suggesting students leave bottles at home—which argues against the paragraph's own position. Only the "However" sentence both faces the objection and keeps supporting the claim, so it creates the cohesion the question asks for.
Question 4
Choose the best transition to introduce a counterargument (claim→counterargument relationship).
"Students should be allowed to redo major tests. , some people argue that retakes are unfair to students who studied the first time. Still, retakes can be limited to students who complete extra practice first."
- For example,
- However, (correct answer)
- Therefore,
- Similarly,
Explanation: This question tests using words, phrases, and clauses to create cohesion (smooth flow, connected ideas) and clarify relationships among claim(s), reasons, and evidence in argumentative writing—employing transitions making explicit how evidence supports reasons, how reasons support claim, how ideas connect. The sentence structure requires a transition that signals a shift from the claim (students should redo tests) to acknowledging an opposing viewpoint (retakes are unfair), which is a counterargument relationship. "However" correctly indicates this contrast, showing that what follows opposes or challenges the initial claim, creating cohesion by explicitly marking where the writer acknowledges opposing views. "For example" (A) would wrongly suggest the counterargument supports rather than challenges the claim, "Therefore" (C) would incorrectly imply the counterargument is a logical conclusion from the claim, and "Similarly" (D) would mistakenly suggest agreement rather than opposition. When introducing counterarguments in argumentative writing, use contrasting transitions like "however," "on the other hand," "nevertheless," or "yet" to clearly signal the shift to opposing viewpoints, maintaining cohesion while showing you've considered multiple perspectives.
Question 5
Select the best transition to connect Reason 2 to the claim by showing it is an additional, same-side reason.
"Claim: Students should have a weekly study hall period.
Reason 1: It gives students time to ask teachers for help.
Evidence: A school in the next district reported fewer missing assignments after adding study hall.
Reason 2: It also gives students time to plan long-term projects instead of rushing the night before."
- Nevertheless,
- Additionally, (correct answer)
- For instance,
- As a result,
Explanation: This question tests using words, phrases, and clauses to create cohesion (smooth flow, connected ideas) and clarify relationships among claim(s), reasons, and evidence in argumentative writing—employing transitions making explicit how evidence supports reasons, how reasons support claim, how ideas connect. The argument structure requires a transition that signals Reason 2 is an additional benefit supporting the same claim about study halls—"Additionally" serves this purpose by indicating this is another positive reason alongside Reason 1. This additive transition creates cohesion by making clear that both reasons work together to support the claim: study halls help with teacher assistance AND with project planning, building a stronger cumulative case. Answer B correctly uses "Additionally" to show same-side support, while Answer A "Nevertheless" would signal contrast, Answer C "For instance" would introduce an example rather than a new reason, and Answer D "As a result" would indicate consequence rather than addition. When presenting multiple reasons supporting the same claim, use additive transitions like "additionally," "furthermore," "moreover," or "also" to signal that you're building your case with complementary points. This helps readers understand that each reason strengthens rather than contradicts the others, creating a unified, persuasive argument.
Question 6
Identify the function of the underlined transition in this argument.
"Students should have a short break between classes. As a result, fewer students would arrive late, since crowded hallways would have more time to clear."
What relationship does the underlined transition signal?
- It introduces a counterargument that disagrees with the claim.
- It signals a cause-and-effect relationship (a result of the previous idea). (correct answer)
- It adds an unrelated new topic.
- It gives a specific example to illustrate a statistic.
Explanation: This question tests using words, phrases, and clauses to create cohesion (smooth flow, connected ideas) and clarify relationships among claim(s), reasons, and evidence in argumentative writing—employing transitions making explicit how evidence supports reasons, how reasons support claim, how ideas connect. The transition "As a result" signals a cause-and-effect relationship, indicating that what follows is a consequence or outcome of what came before. In this argument, the break between classes (cause) would lead to fewer late arrivals because hallways would have time to clear (effect). Choice B correctly identifies this cause-and-effect function, while A incorrectly suggests counterargument, C wrongly claims unrelatedness, and D mistakenly identifies it as exemplification. Understanding transition functions helps writers choose the right connectors: use "as a result," "consequently," or "therefore" for effects; "for example" or "for instance" for illustrations; "however" or "on the other hand" for contrasts.
Question 7
Choose the transition that best shows a cause-and-effect relationship between the evidence and the claim.
"Cafeterias should label foods with common allergens. Some students have severe allergies, and even small amounts can cause dangerous reactions; , clear labels can prevent accidental exposure."
- therefore (correct answer)
- for instance
- however
- meanwhile
Explanation: This question tests using words, phrases, and clauses to create cohesion (smooth flow, connected ideas) and clarify relationships among claim(s), reasons, and evidence in argumentative writing—employing transitions making explicit how evidence supports reasons, how reasons support claim, how ideas connect. The sentence structure presents evidence (students have severe allergies causing dangerous reactions) followed by a conclusion that supports the claim (labels can prevent exposure), requiring a cause-and-effect transition. "Therefore" correctly signals that the need for clear labels is a logical consequence of the allergy danger described in the evidence—because allergic reactions are dangerous, therefore labels are necessary. "For instance" (B) would wrongly suggest an example rather than a conclusion, "however" (C) would incorrectly signal contrast when the ideas support each other, and "meanwhile" (D) would inappropriately suggest simultaneous but unrelated events. When evidence leads to a logical conclusion that supports your claim, use cause-and-effect transitions like "therefore," "thus," "consequently," or "as a result" to make the reasoning explicit and strengthen the argument's cohesion.
Question 8
A student is revising a sentence pair to improve clarity:
"School uniforms can reduce bullying. Students are less likely to be judged for expensive brands."
Which option best combines these ideas using a transition that clearly shows the relationship between the reason and the explanation?
- "School uniforms can reduce bullying, because students are less likely to be judged for expensive brands." (correct answer)
- "School uniforms can reduce bullying, for example students are less likely to be judged for expensive brands."
- "School uniforms can reduce bullying; however, students are less likely to be judged for expensive brands."
- "School uniforms can reduce bullying; in conclusion, students are less likely to be judged for expensive brands."
Explanation: This question tests using words, phrases, and clauses to create cohesion (smooth flow, connected ideas) and clarify relationships among claim(s), reasons, and evidence in argumentative writing—employing transitions making explicit how evidence supports reasons, how reasons support claim, how ideas connect. Option A correctly uses "because" to show a causal relationship—the second part of the sentence explains why uniforms can reduce bullying, creating clear cohesion between the claim and its supporting explanation. The transition makes explicit that being less likely to be judged for brands is the mechanism through which uniforms reduce bullying. Option B incorrectly uses "for example," which would suggest the second part is just one instance rather than an explanation of how uniforms work. Option C uses "however," which wrongly suggests contrast or opposition between the ideas. Option D inappropriately uses "in conclusion" mid-argument for what should be explanatory content. When connecting claims to their explanations or mechanisms, use causal transitions like "because," "since," or "as" to show how one idea explains or causes the other.
Question 9
Which transition best completes the blank to show that the writer is adding another reason that supports the same claim?
"Schools should offer more arts classes. Art helps students express ideas in different ways. arts classes can also build teamwork when students collaborate on performances and group projects."
- Additionally, (correct answer)
- Nevertheless,
- For example,
- Therefore,
Explanation: This question tests using words, phrases, and clauses to create cohesion (smooth flow, connected ideas) and clarify relationships among claim(s), reasons, and evidence in argumentative writing—employing transitions making explicit how evidence supports reasons, how reasons support claim, how ideas connect. Additive transitions like "additionally," "furthermore," and "moreover" signal that the writer is adding another point that supports the same claim, building a stronger argument through multiple reasons. The paragraph presents one benefit of arts classes (expressing ideas differently), and "Additionally" appropriately introduces a second benefit (building teamwork), both supporting the claim for more arts classes. Choice A correctly uses this additive transition, while "Nevertheless" (B) wrongly signals contrast, "For example" (C) incorrectly suggests exemplification rather than addition, and "Therefore" (D) mistakenly indicates conclusion. When presenting multiple reasons supporting the same claim, use additive transitions to signal that you're building your argument with complementary points.
Question 10
Select the best transition to clarify a cause-and-effect relationship between the evidence and the claim.
"Schools should limit homework on weeknights. Many students stay up late finishing assignments; a student survey found that 62% get fewer than 8 hours of sleep on school nights. sleep loss can make it harder to pay attention and remember new information in class."
- For instance,
- In addition,
- Consequently, (correct answer)
- Similarly,
Explanation: The middle sentences show that homework keeps students up late, so most get too little sleep. The final sentence names what that lack of sleep leads to: trouble paying attention and remembering. Because you are showing that one thing causes another, you need a cause-and-effect transition. "Consequently" signals that sleep loss produces those results, making the causal chain clear and connecting the evidence to the claim about limiting homework. "For instance" is wrong because the final sentence is not an example of the survey statistic—it states an effect, not an illustration. "In addition" simply adds another fact side by side, so it hides the cause-and-effect link the sentence actually expresses. "Similarly" points to a comparison between two like ideas, but sleep loss and its consequences are not being compared—one causes the other. Only "Consequently" makes the reasoning flow from evidence to result to conclusion.
Question 11
A student wrote this argument:
"School cafeterias should offer more vegetarian options. Plant-based meals can be healthier. They can also lower the school's environmental impact. Meat production uses a lot of water."
Which transition best fits at the start of the last sentence to clarify that it is evidence supporting the environmental reason?
- Specifically, (correct answer)
- Nevertheless,
- Meanwhile,
- Similarly,
Explanation: The last sentence gives a concrete detail—water usage in meat production—that backs up the earlier reason about environmental impact. "Specifically" is correct because it signals that what follows is a precise piece of evidence that elaborates on the point just made. "Nevertheless" is wrong because it signals contrast or a change of direction, but this sentence agrees with and supports the previous idea rather than opposing it. "Meanwhile" is wrong because it signals that two things are happening at the same time, which doesn't match the relationship here—the water fact isn't a simultaneous event, it's supporting evidence. "Similarly" is wrong because it presents the water usage as a separate, parallel point, when it is actually detail that explains the environmental reason rather than a new comparison. When you want to show that a sentence offers concrete support for a broader claim, transitions like "specifically," "in particular," or "for instance" make that relationship clear.
Question 12
Evaluate which transition choice would FAIL to create cohesion because it signals the wrong relationship.
"Claim: The school library should stay open after school.
Reason: It gives students a quiet place to work.
Evidence: Last year, 120 students reported they could not study at home due to noise.
Transition to next reason: it also provides access to computers for students without internet."
- Additionally,
- Moreover,
- However, (correct answer)
- In addition,
Explanation: This question tests using words, phrases, and clauses to create cohesion (smooth flow, connected ideas) and clarify relationships among claim(s), reasons, and evidence in argumentative writing—employing transitions making explicit how evidence supports reasons, how reasons support claim, how ideas connect. The question asks which transition would FAIL to create cohesion—"However" signals contrast or opposition, which is inappropriate when introducing another supporting reason for keeping the library open, as both reasons work together rather than against each other. Using "However" would confuse readers by suggesting the computer access somehow contradicts or opposes the quiet study space benefit, when actually both reasons support the same claim about extended library hours. Answer C correctly identifies "However" as the problematic choice, while Answers A, B, and D ("Additionally," "Moreover," "In addition") all appropriately signal that computer access is another benefit supporting the claim. When connecting multiple reasons that support the same claim, avoid contrastive transitions like "however," "nevertheless," or "on the other hand"—these should be reserved for introducing opposing views or counterarguments. Using the wrong transition type can undermine your argument's logic and confuse readers about how your ideas relate to each other.
Question 13
Compare the cohesion of the two versions. Which version uses transitions more effectively to clarify how the reasons connect to the claim?
- Version 1, because listing each reason as a separate short sentence keeps the ideas connected without needing transition words.
- Version 2, because transitions like "First," "Additionally," and "As a result" clarify the relationships among the reasons and effects. (correct answer)
- Version 1, because leaving out transitions lets readers decide the connections themselves, which makes the argument sound stronger.
- Version 2, because adding any transition words at the start of a sentence always makes writing flow more smoothly.
Explanation: Version 2 is the stronger choice because its transitions each signal a specific relationship: "First" introduces the opening reason, "Additionally" adds a second reason on the same side, and "As a result" shows the effect those reasons lead to. Together they guide the reader from the claim, through the supporting reasons, to the consequence for learning, so the ideas clearly connect. The option praising Version 1's short, separate sentences is wrong because simply placing ideas next to each other does not show how they relate; readers are left to guess the connections. The option saying Version 1 sounds stronger by leaving out transitions is also wrong—removing the connecting words makes the reasoning less clear, not more convincing. The remaining option about Version 2 is wrong because transitions do not help "automatically"; smooth flow comes from choosing a transition that matches the actual relationship (adding, ordering, or showing cause), not from adding any transition anywhere. When you write arguments, match each transition to the job it does so your reasons and evidence link clearly to your claim.
Question 14
Select the best transition to fill in the blank so the relationship between the ideas is clear.
"Students should be allowed to carry water bottles in class because staying hydrated improves attention. , a university study found that students who drank water during the day made fewer mistakes on quizzes."
- On the other hand,
- For instance, (correct answer)
- As a result,
- In the same way,
Explanation: The first sentence makes a general point: staying hydrated improves attention. The second sentence gives a specific study that backs up that point. You need a transition that signals "here is a concrete case that supports what I just said." "For instance" does exactly this, connecting the general reason to the evidence proving it. "On the other hand" signals a contrast, but the study agrees with the reason rather than opposing it, so it breaks the flow. "As a result" signals cause and effect, as if the study happened because of the first sentence, but the study is offered as proof, not a consequence. "In the same way" signals that two similar ideas are being compared side by side, but the second sentence is not a parallel example—it is direct support for the single claim already made. Only "For instance" correctly shows that the evidence illustrates and strengthens the reason.
Question 15
Identify the function of the underlined transition in the student's argument.
"Students should have less homework on weeknights. Most importantly, many students have after-school responsibilities, such as sports, jobs, or caring for siblings."
What relationship does Most importantly signal?
- It introduces a counterargument that disagrees with the claim.
- It emphasizes that the next reason is the key support for the claim. (correct answer)
- It shows that the next sentence is an example that proves the previous sentence.
- It signals the conclusion of the entire argument.
Explanation: This question tests using words, phrases, and clauses to create cohesion (smooth flow, connected ideas) and clarify relationships among claim(s), reasons, and evidence in argumentative writing—employing transitions making explicit how evidence supports reasons, how reasons support claim, how ideas connect. "Most importantly" is an emphasizing transition that signals hierarchy among reasons—it tells readers that the following reason (students' after-school responsibilities) is the strongest or most significant support for the claim about reducing homework. This transition creates cohesion by explicitly ranking the importance of different reasons rather than simply listing them. Choice B correctly identifies this emphasizing function, while Choice A wrongly suggests it introduces disagreement, Choice C incorrectly claims it signals an example relationship, and Choice D mistakenly identifies it as a conclusion marker. Transitions like "most importantly," "above all," or "primarily" help writers create cohesion by showing readers which reasons carry the most weight in supporting a claim, guiding them through the argument's logical priorities rather than presenting all reasons as equally significant.
Question 16
Read the student's argument and choose the best transition to fill the blank so the relationship between the reason and the evidence is clear.
Claim: Our school should start 30 minutes later.
Reason: Students would get more sleep.
, a district in our state that moved its start time later reported that middle schoolers slept about 40 more minutes per night.
Which transition best fits the blank?
- However,
- For example, (correct answer)
- As a result,
- On the other hand,
Explanation: The sentence after the blank gives a specific piece of proof—a real district where middle schoolers slept about 40 more minutes—that backs up the reason that students would get more sleep. "For example" is the best choice because it signals that a concrete instance is coming to illustrate that reason. "However" signals a contrast, but the district data doesn't disagree with the reason—it supports it. "On the other hand" also sets up an opposing idea, so it wrongly suggests the evidence pushes back against the claim instead of proving it. "As a result" signals cause and effect, treating the sleep data as a consequence of the reason rather than an example that demonstrates it. When you are introducing evidence that shows an instance of your reason, use transitions like "for example," "for instance," or "specifically."
Question 17
Determine the best connector to link the evidence to the reason so the relationship is clear.
Reason: "Longer passing periods would reduce tardies."
Evidence: "Last semester, the school recorded over 300 tardies in the first two minutes after the bell, suggesting students are arriving just slightly late."
Which connector best links the evidence to the reason in a sentence like this?
"Longer passing periods would reduce tardies; , last semester the school recorded over 300 tardies in the first two minutes after the bell…"
- in summary
- for instance (correct answer)
- on the other hand
- instead
Explanation: This question tests using words, phrases, and clauses to create cohesion (smooth flow, connected ideas) and clarify relationships among claim(s), reasons, and evidence in argumentative writing—employing transitions making explicit how evidence supports reasons, how reasons support claim, how ideas connect. The evidence about 300 tardies in the first two minutes provides a specific example that supports the reason that longer passing periods would reduce tardies—it shows students are arriving just slightly late, suggesting time is the issue. "For instance" correctly signals this reason-to-evidence relationship, indicating that what follows is concrete data exemplifying why the reason is valid. "In summary" (A) would wrongly suggest a conclusion rather than supporting evidence, "on the other hand" (C) would incorrectly imply contrast when the evidence supports the reason, and "instead" (D) would inappropriately suggest replacement rather than support. When presenting evidence to support reasons in arguments, use exemplifying transitions like "for instance," "for example," or "such as" to clearly show that specific data or examples are being provided to validate abstract claims, creating the cohesion that makes arguments convincing.
Question 18
A student is adding a second reason to support a claim. Which transition best clarifies that the new sentence is an additional reason (reason→reason relationship)?
Claim: "Our town should build more bike lanes."
Reason 1: "Bike lanes make commuting safer."
, "bike lanes can also reduce traffic congestion because more people choose to bike for short trips."
- Additionally, (correct answer)
- On the other hand,
- For instance,
- Consequently,
Explanation: The writer already gave one reason (safety) and now wants to stack on a second, separate reason (less traffic) that also backs the claim. "Additionally" signals that another independent reason is being added to the argument, which is exactly the reason→reason link the sentence needs.
"On the other hand" signals a contrast or opposing idea, but the two reasons agree and both support building bike lanes, so it wrongly suggests they conflict. "For instance" introduces an example that illustrates the previous point, so it would falsely make the traffic reason sound like proof of the safety reason instead of a new reason of its own. "Consequently" shows cause and effect, so it would wrongly claim that reducing traffic happens as a result of bikes being safer, when the two reasons are simply separate supports.
When you list several reasons for the same claim, additive transitions like "additionally," "also," or "furthermore" make it clear that each reason stands on its own while building your argument.
Question 19
A student is writing an argument about homework:
"Teachers should assign less homework on weeknights. Students need time for family responsibilities. A poll of 200 students showed that 48% babysit younger siblings after school. Too much homework can also reduce sleep."
Which transition best fits at the start of the last sentence to show it is an additional reason supporting the same claim?
- As a result,
- For this reason,
- Additionally, (correct answer)
- For instance,
Explanation: The paragraph gives one reason for less homework (family responsibilities), backs it with poll data, and then the last sentence introduces a second, separate reason: too much homework reduces sleep. You need a word that signals another reason of equal importance is being added. "Additionally" does exactly that, showing the two reasons work together to support the same claim. "As a result" signals cause and effect, which would wrongly suggest that reduced sleep is caused by the family responsibilities mentioned before it, rather than being its own reason. "For this reason" also points backward to a cause, implying the sleep sentence follows from the earlier statement instead of standing as a new, independent point. "For instance" introduces an example, which would incorrectly present the sleep problem as evidence illustrating the family-responsibilities reason rather than a separate reason of its own. When you are stacking multiple reasons to build an argument, use additive transitions like "additionally," "furthermore," or "moreover."
Question 20
Choose the transition that best shows a cause-and-effect relationship.
"The city should plant more trees near sidewalks. trees provide shade, sidewalks stay cooler, which can reduce heat-related illness during summer."
- Because (correct answer)
- Even though
- In addition to how
- In the same way that
Explanation: The blank needs a transition that shows one thing causes another: the shade from trees is the reason sidewalks stay cooler and heat-related illness drops. "Because" makes that cause-and-effect chain clear, connecting the reason directly to the result. "Even though" signals a contrast, so it wrongly suggests the shade should NOT lead to cooler sidewalks, which contradicts the sentence. "In addition to how" simply adds another point instead of showing that shade causes the cooler sidewalks, so the logical link disappears. "In the same way that" sets up a comparison, treating shade and cooler sidewalks as similar things rather than as a cause and its effect. Only "because" builds the smooth, logical flow from cause to effect that the sentence needs. When you want readers to follow how one idea leads to another in your argument, causal transitions like "because," "since," or "as a result" make that connection explicit.
