A.I. Explanation:

Correct Answer: Mei Chen

Why this is correct: Sofia writes to the person whose name is listed for vinegar. In the Vinegar row, the contact is Mei Chen.

Tips: When the To line is blank, read the email first to learn the topic, then find the person linked to that topic.

Why the other options are wrong:

• Priya Nair: Priya Nair is the contact for dish soap, not vinegar.
• Daniel Roy: Daniel Roy is the contact for laundry powder, not vinegar.
• Lena Park: Lena Park is the shop manager at the front desk. The vinegar question goes to the vinegar contact, Mei Chen.

Correct Answer: a glass bottle

Why this is correct: The Vinegar row says glass bottle only. Sofia's olive oil bottle is the kind of container she is asking about.

Tips: Make sure you are reading the row for the product named in the sentence.

Why the other options are wrong:

• a bottle with a pump lid: A pump lid bottle is for dish soap. The vinegar rule does not mention a pump lid.
• a wide-mouth jar: A wide-mouth jar is for laundry powder, not for vinegar.
• a plastic bottle: The Vinegar row says glass bottle only, so a plastic bottle is not allowed for vinegar.

Correct Answer: a screw cap

Why this is correct: The Vinegar row says a screw cap is required. Sofia wants to know if her old olive oil bottle is fine as long as it meets this rule.

Tips: Look for words like required or only. They show the rule you must follow.

Why the other options are wrong:

• a pump lid: A pump lid is needed for dish soap. It is not the rule for vinegar.
• a wide mouth: A wide mouth is needed for laundry powder, not for a vinegar bottle.
• a metal lid: The Vinegar row asks for a screw cap on a glass bottle. It does not list a metal lid as the rule.

Correct Answer: the Liquids Counter

Why this is correct: The Dish Soap row lists the Liquids Counter as the place in the shop. Sofia is talking about her dish soap bottle in this sentence.

Tips: Check which product the sentence is about before you look across the row.

Why the other options are wrong:

• the Dry Goods Wall: The Dry Goods Wall is where laundry powder is, not dish soap.
• the Cleaning Bar: The Cleaning Bar is for vinegar. Sofia is talking about dish soap here.
• the front desk: The front desk is where every container is weighed first. After weighing, dish soap is filled at the Liquids Counter.

Correct Answer: fill each bottle for you

Why this is correct: Sofia is writing to the vinegar contact, so the counter she looks after is the Cleaning Bar. The Vinegar row says staff fill your bottle, which is why Sofia thinks she may have to wait.

Tips: Words like your or that can point to something from earlier in the email. Work out what they mean first.

Why the other options are wrong:

• let you scoop it yourself: You scoop it yourself at the Dry Goods Wall for laundry powder, not at the Cleaning Bar.
• weigh each container first: Containers are weighed at the front desk, not at the vinegar counter, so this does not describe the Cleaning Bar.
• let you fill it yourself: Filling it yourself is the rule for dish soap at the Liquids Counter. At the Cleaning Bar, staff fill your bottle.

Correct Answer: check whether her bottle can be used for vinegar

Why this is correct: Sofia says she has a question about vinegar and asks if her old olive oil bottle is acceptable. This question is the main reason she writes.

Tips: The main purpose is often in a direct question or request. Look for could you or please.

Why the other options are wrong:

• complain about the shop's container rules: Sofia does not complain. She is only asking how to follow the rules.
• order cleaning products for home delivery: Sofia plans to visit the shop on Saturday. She never asks for delivery.
• ask for a job at the Cleaning Bar: Sofia is a customer. She does not ask about work.

Correct Answer: has checked which container each product needs

Why this is correct: Sofia plans to bring a coffee tin for laundry powder. The diagram says laundry powder needs a wide-mouth jar or tin, so she has matched the container to the rule.

Tips: Compare what the writer plans to do with the rule in the diagram to see what the plan shows.

Why the other options are wrong:

• expects the shop to give her a free jar: Sofia is bringing her own coffee tin. The guide does not offer free jars to anyone.
• will ask the vinegar staff to fill it: Laundry powder is scooped by customers at the Dry Goods Wall, not filled by the vinegar staff.
• thinks every product needs a glass bottle: A coffee tin is not a glass bottle, so she knows the rules are different for each product.

Correct Answer: polite and well prepared

Why this is correct: Sofia says hello, thanks the reader and asks her question kindly. She has also read the guide and washed her bottle, so she is well prepared.

Tips: For tone, notice both how the writer speaks and what they have already done.

Why the other options are wrong:

• annoyed and demanding: Sofia does not sound upset. She asks politely and thanks the reader.
• nervous and confused: Sofia understands most of the rules and asks one clear question.
• casual and careless: Sofia has checked the guide closely and cleaned her bottle, so she is careful.
