Understanding Requests And SuggestionsQuestion 1 of 10

Read the following group chat messages:

陈老师：同学们，下周四我们班要去博物馆参观。请大家提前在网上预约，不然进不去。 学生甲：老师，我们需要自己买票吗？ 陈老师：不用，学校已经统一购票了，但是每个人还是必须自己预约，否则门口不让进。 学生乙：老师，我下周四上午有事，能不能下午去？ 陈老师：下午也可以，博物馆下午四点关门，建议大家最晚两点进去，留足够的时间参观。

A student reads this chat and concludes: 'I need to buy a ticket online and make a reservation, and I should arrive by 2 p.m. at the latest.' How many parts of this conclusion are incorrect?

One part is incorrect: tickets are already purchased by the school, so no individual ticket purchase is needed, but the reservation requirement and the 2 p.m. arrival suggestion are both accurate.
Two parts are incorrect: neither ticket purchase nor reservation is required from individual students, because the school handles all arrangements including entry registration.
No parts are incorrect: students must purchase tickets online, make individual reservations, and arrive by 2 p.m. to have enough time before the 4 p.m. closing.
One part is incorrect: the 2 p.m. arrival is not a hard requirement but only a suggestion, while the ticket purchase and reservation requirements are both accurately stated in the student's conclusion.

Question 1

Read the following group chat messages:

陈老师：同学们，下周四我们班要去博物馆参观。请大家提前在网上预约，不然进不去。 学生甲：老师，我们需要自己买票吗？ 陈老师：不用，学校已经统一购票了，但是每个人还是必须自己预约，否则门口不让进。 学生乙：老师，我下周四上午有事，能不能下午去？ 陈老师：下午也可以，博物馆下午四点关门，建议大家最晚两点进去，留足够的时间参观。

A student reads this chat and concludes: 'I need to buy a ticket online and make a reservation, and I should arrive by 2 p.m. at the latest.' How many parts of this conclusion are incorrect?

  1. One part is incorrect: tickets are already purchased by the school, so no individual ticket purchase is needed, but the reservation requirement and the 2 p.m. arrival suggestion are both accurate. (correct answer)
  2. Two parts are incorrect: neither ticket purchase nor reservation is required from individual students, because the school handles all arrangements including entry registration.
  3. No parts are incorrect: students must purchase tickets online, make individual reservations, and arrive by 2 p.m. to have enough time before the 4 p.m. closing.
  4. One part is incorrect: the 2 p.m. arrival is not a hard requirement but only a suggestion, while the ticket purchase and reservation requirements are both accurately stated in the student's conclusion.
Explanation: When reading group chat messages in Mandarin, your job is to carefully track who is responsible for what action. Misreading the source of an action (school vs. student) is one of the most common errors on detail-comprehension questions like this one. Let's trace what the chat actually says. 陈老师 clearly states: "学校已经统一购票了" — the school has already purchased tickets collectively. So individual students do not need to buy tickets. However, the teacher also says each person "必须自己预约" (must make their own reservation), otherwise they won't be allowed in at the entrance. Regarding timing, the teacher suggests (建议) arriving by 2 p.m. at the latest to have enough time before the 4 p.m. closing — this is a recommendation, not a hard rule. The student's conclusion says "I need to buy a ticket online," which is wrong. The reservation part is correct, and the 2 p.m. guidance is accurate as a suggestion. That means exactly one part of the student's conclusion is incorrect — making A the right answer. B is wrong because it claims reservations are also handled by the school, but the teacher explicitly says each student must reserve individually. C is wrong because it repeats the student's flawed conclusion and treats it as fully accurate. D is wrong in the opposite direction — it claims the ticket purchase statement is correct when it clearly isn't, since the school already handled that. Your takeaway: always pay attention to subjects in Chinese sentences. "学校已经统一购票了" tells you who bought the tickets. When a passage distinguishes school responsibilities from student responsibilities, expect exam questions to test exactly that boundary.

Question 2

Read the following text message exchange:

Li Ming: 我们明天下午两点在图书馆见面讨论项目，你觉得怎么样？ Wang Fang: 两点我还有课，能不能推迟一个小时？ Li Ming: 没问题，但是图书馆四点就关门了，我们去咖啡馆吧，那里可以待得更久。 Wang Fang: 好的，就这么定了。

Which of the following best describes the chain of requests and suggestions that led to the final plan?

  1. Wang Fang suggested meeting at the library at 3 p.m.; Li Ming agreed but then proposed the café because the library closes at 4 p.m. and they need more time.
  2. Li Ming originally suggested the library at 2 p.m.; Wang Fang requested a one-hour delay; Li Ming then suggested the café instead of the library because the delayed time would leave too little time there. (correct answer)
  3. Li Ming originally suggested the café at 2 p.m.; Wang Fang requested a one-hour delay to 3 p.m.; Li Ming agreed and they kept the café as the location from the start.
  4. Wang Fang suggested the café to avoid the library's closing time; Li Ming agreed to move the meeting to 3 p.m. at the café to accommodate Wang Fang's schedule.
Explanation: When a question asks you to trace a "chain of events" through a conversation, your job is to track who said what, in what order, and resist the temptation to mix up speakers or reorder the sequence. In this exchange, Li Ming opens by proposing the library at 2 p.m. Wang Fang responds that she has class at 2 p.m. and asks to push it back one hour — making the new proposed time 3 p.m. Li Ming agrees to the delay but then points out a problem: the library closes at 4 p.m., which would leave them only one hour. To solve this, Li Ming suggests switching to a café, where they can stay longer. Wang Fang accepts. So the correct answer is B — it accurately captures Li Ming's original library-at-2 proposal, Wang Fang's one-hour delay request, and Li Ming's café suggestion as the solution to the time crunch. Answer A incorrectly says Wang Fang suggested the library at 3 p.m. — Wang Fang only requested a time change, not a location. Answer C falsely claims Li Ming originally suggested the café at 2 p.m., when the café was never mentioned until after the scheduling conflict arose. Answer D attributes the café idea to Wang Fang, but it was Li Ming who proposed the café; Wang Fang simply agreed. A useful habit: when a conversation question involves multiple turns, mentally note each speaker's contribution separately before choosing an answer. Mixing up who initiated an idea is exactly the trap these questions are designed to set.

Question 3

Listen to the following conversation at a help desk:

顾客：你好，我买的这个电饭锅用了三天就坏了，我想换一个新的。 工作人员：您好，请问您有购买凭证吗？ 顾客：我有收据，但是我把包装盒扔了。 工作人员：没关系，有收据就可以。不过我建议您先让我们的技术人员检查一下，如果是产品质量问题，我们可以直接换新的；如果是使用不当，我们可以帮您维修。 顾客：我确定是质量问题，我操作没有问题的。 工作人员：我理解您的想法，但是按照我们的流程，还是需要先检查才能处理，您看可以吗？

The staff member makes two suggestions during this exchange. What are they, and what is the staff member's underlying reason for insisting on the second suggestion despite the customer's objection?

  1. The staff suggests the customer find the original packaging and then have the product inspected; the staff insists on inspection because missing packaging voids the warranty under store policy.
  2. The staff suggests the customer bring a receipt and then submit a written complaint; the staff insists on the written complaint because verbal claims of quality defects are not accepted as sufficient evidence under store policy.
  3. The staff suggests having the product inspected by a technician, and then either replacing or repairing it based on the findings; the staff insists on inspection because store procedure requires it before any action can be taken, regardless of the customer's certainty. (correct answer)
  4. The staff suggests an immediate replacement and then a follow-up inspection to confirm the defect; the staff insists on the follow-up inspection because replacements are conditional on confirmed quality issues per store policy.
Explanation: When listening to service-desk conversations in Mandarin, train yourself to track two things simultaneously: the sequence of actions being proposed and the reason behind any resistance. This question tests both. In the dialogue, the staff member (工作人员) makes one core suggestion: have a technician inspect the product first (先让我们的技术人员检查一下). Based on that inspection, two outcomes follow — either a direct replacement if it's a quality issue (换新的) or a repair if it's user error (维修). When the customer insists it's definitely a quality problem, the staff member doesn't back down, citing store procedure (按照我们的流程，还是需要先检查才能处理). This makes C correct — it accurately captures the conditional structure of the suggestion and identifies procedure, not the customer's certainty, as the deciding factor. A is wrong on two counts: the staff never asks the customer to retrieve original packaging (the customer volunteers that she threw it away), and the staff explicitly says the receipt alone is sufficient. B invents a written complaint process entirely — nothing in the dialogue mentions submitting anything in writing. D reverses the sequence; the staff never offers an immediate replacement. The inspection comes before any resolution, not after. A useful pattern to remember: in Mandarin service dialogues, phrases like 按照我们的流程 ("according to our procedure") signal that the staff is deflecting a personal objection with institutional policy — a common conversational move worth recognizing instantly on this exam.

Question 4

Listen to the following conversation at a restaurant:

Waiter: 您好，请问您想点什么？我们今天的特色菜是红烧肉，不过如果您不吃辣，我建议您试试我们的清蒸鱼，味道非常鲜美。 Customer: 我其实不太能吃辣，但是我朋友特别喜欢辣的。 Waiter: 那您可以点一个清蒸鱼，再加一个麻婆豆腐怎么样？两个人吃刚刚好。

What does the waiter ultimately suggest the customer order, and what is the waiter's reasoning?

  1. Order the red-braised pork and mapo tofu, because the special of the day should be tried and the spicy dish will satisfy the customer's friend.
  2. Order the steamed fish and mapo tofu, because the steamed fish suits the customer who cannot eat spicy food, and the mapo tofu satisfies the friend who likes spicy food. (correct answer)
  3. Order the steamed fish and red-braised pork, because the waiter wants the customer to enjoy the non-spicy special and also have a hearty meat dish for the friend.
  4. Order two portions of steamed fish, because both the customer and the friend should avoid spicy food when dining together to keep the meal balanced.
Explanation: When listening to service-industry conversations in Mandarin, pay close attention to how the speaker balances multiple people's preferences — waiters often craft compromise suggestions that address everyone at the table. In this dialogue, the waiter learns two key facts: the customer cannot eat spicy food (不太能吃辣), but the customer's friend loves spicy food (特别喜欢辣的). Armed with this information, the waiter proposes a practical solution: order the steamed fish (清蒸鱼) for the customer, since it was already introduced as the non-spicy option, and add mapo tofu (麻婆豆腐) for the spice-loving friend. The waiter even justifies the portion logic with 两个人吃刚刚好 — "just right for two people." This makes B the correct answer: it accurately captures both dishes and the reasoning behind each choice. A is wrong because the waiter never returns to the red-braised pork (红烧肉) as a final recommendation — it was mentioned early but set aside once the customer revealed they avoid spicy food. C incorrectly pairs steamed fish with red-braised pork, a combination the waiter never suggests. D misreads the situation entirely — the waiter does not recommend two steamed fish dishes, and ignoring the friend's spicy preference would contradict the waiter's whole approach. A useful strategy: in listening comprehension questions about recommendations, track who each suggestion is meant for. Mandarin service conversations often tailor orders to individual diners, so mapping each dish to each person will help you select the precise answer.

Question 5

听下面这段对话：

售货员：您好，您是要买运动鞋吗？ 顾客：对，我想买一双跑步鞋，但是我不知道该选哪个牌子。 售货员：我建议您选这款，它的缓震效果很好，而且透气性强。不过如果您主要在室内跑步，那款灰色的可能更适合您，底部更薄一些。 顾客：我一般在公园跑，路面不太平整。 售货员：那还是第一款更合适，底部厚，保护性更强。

Based on the salesperson's suggestions, which shoe is recommended for the customer and why does the salesperson change the recommendation mid-conversation?

  1. The gray shoe is recommended because the customer runs in a park, and the salesperson changes the suggestion after learning the terrain is uneven and realizes the thin sole offers better grip on rough surfaces.
  2. The first shoe (with strong cushioning) is the final recommendation; the salesperson briefly mentioned the gray shoe as an alternative for indoor running, but switched back to the first shoe once learning the customer runs outdoors on uneven ground. (correct answer)
  3. The first shoe is recommended throughout the conversation without any change, because the salesperson immediately identifies park running as the customer's need and never seriously considers the gray shoe.
  4. The gray shoe is the final recommendation because its thinner sole allows better contact with uneven park terrain, and the salesperson's mention of the first shoe was only to contrast cushioning levels.
Explanation: When listening to sales conversations in Mandarin, pay attention to how recommendations evolve — salespeople often adjust suggestions based on new information the customer provides. This question tests whether you can track that conversational flow accurately. The salesperson opens by recommending the first shoe (缓震效果好，透气性强 — good cushioning, strong breathability). They then conditionally mention the gray shoe, using "如果您主要在室内跑步" (if you mainly run indoors) — this is a hypothetical branch, not a firm new recommendation. Once the customer reveals they run in a park on uneven ground (路面不太平整), the salesperson returns to the first shoe, citing its thick sole and stronger protection (底部厚，保护性更强). Answer B correctly captures this arc: the gray shoe was a conditional detour, and the first shoe is both introduced first and confirmed last. Answer A is wrong because it misidentifies the final recommendation — the gray shoe is not what the salesperson ends on, and thinner soles do not provide better grip on rough terrain according to the dialogue. Answer C is tempting but inaccurate — the salesperson does genuinely introduce the gray shoe as a real option mid-conversation, so calling it a non-consideration misreads the dialogue. Answer D inverts the conclusion entirely; the gray shoe's thin sole is presented as a limitation for uneven terrain, not an advantage. A useful strategy: in Mandarin listening passages, watch for conditional phrases like 如果…那… (if…then…) — they signal hypothetical branches that may or may not become the final recommendation.

Question 6

Read the following office memo excerpt:

各位同事：

明天下午的会议原定在三楼会议室举行。由于三楼正在装修，请大家改到五楼的大会议室开会。另外，由于五楼的会议室比较大，建议大家坐得近一点，方便交流。会议时间不变，仍然是下午三点。如果有人需要提前准备材料，请在今天下午五点前发给张经理。

A colleague reads this memo and tells you: 'The meeting time changed, and we should prepare materials before 5 p.m. tomorrow.' How many details has the colleague gotten wrong?

  1. Two details are wrong: the meeting time did not change, and the material deadline is today at 5 p.m., not tomorrow at 5 p.m. (correct answer)
  2. One detail is wrong: the meeting time did not change, but the deadline for submitting materials is correctly stated as 5 p.m. tomorrow.
  3. Two details are wrong: the meeting location did not change according to the memo, and the material deadline is today, not tomorrow.
  4. One detail is wrong: the material deadline is indeed tomorrow at 5 p.m., but the colleague correctly identified that the meeting time stayed the same.
Explanation: When reading a memo in Mandarin, your job is to track every specific detail — times, locations, deadlines — and compare them carefully against what someone claims. Miscommunication questions like this one test whether you can spot multiple errors simultaneously, not just the most obvious one. The memo states two things clearly: 会议时间不变，仍然是下午三点 ("the meeting time is unchanged, still 3 p.m.") and 请在今天下午五点前发给张经理 ("please send materials to Manager Zhang before 5 p.m. today"). The colleague made two separate mistakes: they said the meeting time changed (it didn't — only the location changed), and they said the material deadline is tomorrow at 5 p.m. (it's today). That makes answer A correct. Looking at why the other choices miss the mark: B is wrong because it only catches one error — it incorrectly accepts "5 p.m. tomorrow" as accurate when the memo explicitly says 今天 (today). C is wrong on two counts — the location did change (from the third floor to the fifth floor), and while it correctly identifies the deadline error, its reasoning about the location is backwards. D is the sneakiest trap: it says the colleague "correctly identified that the meeting time stayed the same," but the colleague actually said the time changed — the exact opposite of what happened. As a study tip: on memo-reading questions, underline time words (今天, 明天, 仍然) and negations (不变) first. These tiny words carry the biggest factual weight and are the most common source of deliberate errors in answer choices.

Question 7

Listen to the following phone call:

A: 喂，你好，我想预订一个房间，下周五到周日，两个晚上。 B: 好的，请问您需要标准间还是大床房？ A: 大床房吧，但是如果大床房没有了，标准间也可以。 B: 我查一下……大床房还有，但是朝街的那间比较吵，我建议您选朝内院的那间，安静一些，价格也一样。 A: 好，就按您说的吧。

What type of room does the caller end up booking, and what was the key factor in the hotel staff's suggestion?

  1. A standard room facing the inner courtyard, because the large bed rooms were fully booked and the standard room is quieter than the street-facing option.
  2. A standard room facing the street, because the large bed rooms were unavailable and the street-facing standard room was the only remaining option at the same price.
  3. A large bed room facing the street, because the caller's first preference was a large bed room and the staff confirmed availability without changing the room type or view.
  4. A large bed room facing the inner courtyard, because the street-facing large bed room is noisy, and the inner courtyard option is quieter at the same price. (correct answer)
Explanation: When listening to a service conversation in Mandarin, pay close attention to the staff member's recommendation and the reason given for it — these details often form the core of comprehension questions. In this dialogue, the caller requests a 大床房 (large bed room) as their first choice, with a standard room as a backup only if no large bed rooms are available. The staff member checks availability and confirms that large bed rooms are still available (「大床房还有」), so the room type never changes. However, the staff notes that the street-facing room (朝街的那间) is quite noisy (比较吵) and recommends the inner courtyard-facing room (朝内院的那间) instead, emphasizing that it is quieter (安静一些) and costs the same (价格也一样). The caller agrees: 「就按您说的吧」— "I'll go with what you suggest." This confirms the correct answer is D: a large bed room facing the inner courtyard, chosen because the street-facing option is noisy and the courtyard option is equally priced but quieter. Answer A is wrong on two counts: the room type is incorrect (it says standard room) and the reason is fabricated — large bed rooms were not fully booked. Answer B makes the same error about availability and also incorrectly identifies the room type. Answer C gets the room type right but misses the crucial detail about which large bed room — the caller ended up with the courtyard-facing room, not the street-facing one. As a study tip, listen carefully for contrast words like 但是 ("but") and recommendation phrases like 我建议 ("I suggest") — they signal that important information is about to shift or be refined.

Question 8

Listen to the following conversation between colleagues:

同事A：我们下个月要给新员工做入职培训，你有什么建议？ 同事B：我建议把培训分成两天，第一天介绍公司文化和规章制度，第二天做实际操作练习。 同事A：两天会不会太长了？新员工可能觉得无聊。 同事B：那你可以在每个环节结束后加一个小互动，让大家提问或者分组讨论，这样效果会更好。另外，培训材料最好提前一周发给新员工，让他们有时间预习。 同事A：提前发材料这个主意不错，但是互动环节我担心会占用太多时间。

Colleague A accepts one of Colleague B's suggestions and expresses concern about another. Which suggestion is accepted, which raises concern, and what is the specific nature of the concern?

  1. A accepts the two-day training format and is concerned about sending materials one week in advance, worrying that new employees may not have enough time to review them before their first day.
  2. A accepts the interactive activities idea and is concerned about the two-day format, fearing that new employees will find it too long and lose interest before the second day.
  3. A accepts sending training materials one week in advance and is concerned that interactive activities will take up too much time during the training sessions. (correct answer)
  4. A accepts the two-day training format and is concerned that interactive activities will take up too much time, noting that group discussions in particular are difficult to keep within schedule.
Explanation: When listening to workplace conversations in Mandarin, pay close attention to contrast markers and response patterns — they reveal which ideas a speaker accepts versus questions. Here, 同事A's final line is the key: "提前发材料这个主意不错" (sending materials in advance is a good idea) directly signals acceptance, while "但是互动环节我担心会占用太多时间" (but I'm worried interactive activities will take up too much time) signals concern. This confirms C — A accepts sending materials one week early and worries that interactive activities will consume too much training time. Choice A is wrong on both counts. A never questions the one-week timeline or suggests new employees won't have enough review time — that concern is entirely fabricated. Choice B gets the accepted suggestion wrong entirely. While A does raise the concern about two-day training feeling too long, that happens earlier in the conversation, before B offers the interactive activities idea. A never actually accepts the interactive activities suggestion — in fact, A expresses concern about it. Choice D is a trap because A does mention the two-day format early on, but A never accepts it — A questions it. Additionally, D's detail about "group discussions being hard to schedule" is an invented specificity not found anywhere in the passage. A useful strategy: in Mandarin listening comprehension, the conjunction 但是 (but) almost always signals a pivot from agreement to reservation. Train yourself to listen for 不错/好 (acceptance) followed by 但是/担心 (concern) — this structure is a reliable map of a speaker's mixed response.

Question 9

Read the following conversation between two students:

小红：明天的考试你复习得怎么样了？ 小明：还差得远呢，我不知道从哪里开始。 小红：你应该先把课本上的重点词汇复习一遍，然后再做练习题。别一开始就做题，那样效率很低。 小明：但是老师说考试会有听力部分，我听力很差。 小红：那你今晚先复习词汇，明天早上留一个小时专门练听力，考试是下午两点，时间够的。

According to Xiao Hong's suggestions, in what order should Xiao Ming study, and what is her reasoning for placing listening practice last among the study tasks?

  1. Xiao Ming should do practice exercises first, then review vocabulary tonight, and then do listening practice in the morning; Xiao Hong places listening last because she believes exercises build the vocabulary context needed before targeted listening work.
  2. Xiao Ming should do listening practice tonight and vocabulary review tomorrow morning; Xiao Hong suggests this reversed order because listening practice is more urgent given Xiao Ming's weakness and should be addressed while the mind is freshest.
  3. Xiao Ming should review vocabulary tonight and do listening practice the next morning, skipping practice exercises entirely; Xiao Hong places listening last because Xiao Ming's weakness in that area requires the most focused, uninterrupted study block.
  4. Xiao Ming should review vocabulary tonight, do practice exercises at some point, and do listening practice the next morning; Xiao Hong places listening in the morning because there is still enough time before the 2 p.m. exam. (correct answer)
Explanation: When a question asks you to reconstruct a sequence of actions from a conversation, your job is to track each individual recommendation and the reasoning behind it — not just the general gist. In Chinese conversations especially, the logic connecting steps is often embedded in phrases like 然后 (then), 先 (first), and time anchors like 今晚 (tonight) and 明天早上 (tomorrow morning). Xiao Hong gives Xiao Ming a clear, layered plan: review key vocabulary from the textbook tonight (今晚先复习词汇), do practice exercises at some point (然后再做练习题), and save listening practice for tomorrow morning (明天早上留一个小时专门练听力). Her reason for scheduling listening in the morning is explicitly practical — the exam is at 2 p.m. (考试是下午两点), so there is still enough time. That makes D the correct answer, because it accurately captures all three steps and the stated rationale. Choice A gets the order completely backwards — Xiao Hong explicitly says not to start with practice exercises (别一开始就做题), so placing them first contradicts the passage directly. Choice B reverses the entire schedule, putting listening tonight and vocabulary tomorrow, which is the opposite of what Xiao Hong recommends. Choice C is close but contains a critical error: it says practice exercises are skipped entirely, when Xiao Hong actually includes them as a step between vocabulary review and listening. A useful strategy here: when a question asks about sequence and reasoning, verify both elements separately before choosing. Many traps, like C, get the sequence partially right but distort one detail. Always confirm that the why in the answer matches the why in the passage.

Question 10

Read the following exchange at a pharmacy:

顾客：我最近睡眠不好，想买一些帮助睡眠的药。 药剂师：您的睡眠问题是入睡困难，还是容易早醒？ 顾客：主要是入睡困难，躺下来脑子停不下来。 药剂师：我建议您先试试这种植物提取的助眠产品，副作用比较小。不过如果您试了一周还是没有改善，建议您去看医生，开具处方药。另外，睡前两小时不要用手机，这个习惯改变一下可能也会有帮助。 顾客：好的，那我先买这个试试。如果一周后还是不行，我再去看医生。

The pharmacist gives the customer three pieces of advice. Which of the following correctly identifies all three and accurately represents the condition attached to the second piece of advice?

  1. Try the plant-based sleep aid; see a doctor if symptoms worsen within one week; avoid using a phone within two hours of sleeping — the condition for seeing a doctor is worsening symptoms, not simply a lack of improvement.
  2. Try the plant-based sleep aid; see a doctor if there is no improvement after one week; avoid using a phone within two hours of sleeping — the condition for seeing a doctor is no improvement after one week of trying the product. (correct answer)
  3. Try the plant-based sleep aid; see a doctor immediately if the product causes side effects; avoid using a phone for two hours after waking — the condition for seeing a doctor is experiencing side effects from the plant-based product.
  4. Try the prescription sleep medication first; see a doctor to confirm the dosage after one week; avoid using a phone within two hours of sleeping — the condition for seeing a doctor is to verify that the prescription dosage is correct.
Explanation: When a passage contains a multi-part exchange, your job is to track each piece of advice precisely — both its content and any conditions attached to it. A single misread word can flip the meaning entirely. In the pharmacist's dialogue, three pieces of advice are clearly given: (1) try the plant-based sleep aid first because it has fewer side effects, (2) see a doctor if there is no improvement after one week, and (3) avoid using your phone within two hours of bedtime. The key phrase for the second piece is "试了一周还是没有改善" — "if after trying it for one week there is still no improvement." This confirms that B is correct: the condition is lack of improvement after one week, not anything else. Choice A distorts the condition by saying the trigger is "worsening symptoms," but the pharmacist says nothing about symptoms worsening — only that improvement hasn't occurred. That's a meaningful difference. C makes two errors: it says the doctor visit is triggered by side effects from the product (the pharmacist actually highlights low side effects as a selling point), and it misrepresents the phone advice as "two hours after waking" rather than two hours before sleeping. D is almost entirely fabricated — the pharmacist explicitly recommends the plant-based product instead of prescription medication, not the other way around, and the doctor visit has nothing to do with verifying dosage. As a study habit, when reading pharmacy or medical dialogues in Mandarin, slow down on conditional phrases like "如果…还是…" ("if… still…") — they carry the exact logical conditions that exam questions love to test.
