A.I. Explanation:

Correct Answer: milk

Why this is correct: Milk is on the Throw Out If Warm list. The food was warm for four and a half hours, so the milk must go.

Tips: A blank in the subject line is still part of the email. Use the whole email and the guide.

Why the other options are wrong:

• butter: Butter is on the Usually Safe to Keep list, so Leo can keep it.
• hard cheese: Hard cheese in a block is usually safe to keep, so it stays.
• whole fruit: Whole fruit is on the Usually Safe to Keep list. It does not need to go.

Correct Answer: the block of hard cheese and whole apples

Why this is correct: Hard cheese in a block and whole fruit are both on the Usually Safe to Keep list.

Tips: When an answer has two foods, check that both are safe, not just one.

Why the other options are wrong:

• the cut melon and milk: Cut fruit and milk are both on the Throw Out If Warm list.
• the yogurt and whole apples: The apples are safe, but yogurt is on the Throw Out If Warm list.
• the cooked chicken and block of hard cheese: The cheese is safe, but cooked chicken must be thrown out.

Correct Answer: may go back into the freezer

Why this is correct: The Frozen Vegetables row says they may go back into the freezer if ice crystals remain.

Tips: Look for the exact condition in the guide, such as ice crystals, and match it.

Why the other options are wrong:

• should be cooked within one day: This rule is for vegetables that are soft but still cold. The peas still have ice.
• must be thrown out with the rice: Frozen vegetables are thrown out only after two warm hours. The peas are still icy.
• can stay on the counter like whole fruit: Only whole fruit can stay on the counter. The guide does not say this about peas.

Correct Answer: two hours

Why this is correct: The Throw Out If Warm row says to throw food out after more than two hours above 4 C.

Tips: Similar numbers can appear in different rows. Check which food each number is about.

Why the other options are wrong:

• four hours: Four hours is how long a closed fridge usually stays cold. It is not the rule for rice.
• one day: One day is how long a half-full freezer stays frozen, not a fridge rule.
• two days: Two days is for a full freezer. It has nothing to do with cooked rice.

Correct Answer: two days

Why this is correct: Priya says the freezer is full. The Fridge Timing row says a full freezer stays frozen about two days.

Tips: Small words like full or half-full can change the answer. Read them carefully.

Why the other options are wrong:

• one day: One day is for a half-full freezer. Priya says the freezer is full.
• four hours: Four hours is how long a closed fridge stays cold, not a freezer.
• two hours: Two hours is the limit for warm food in the Throw Out If Warm row.

Correct Answer: arrange a careful check of the food while away

Why this is correct: Priya asks Leo to sort the food using the guide while Priya is out of town.

Tips: Ask yourself what the writer wants the reader to do.

Why the other options are wrong:

• ask Leo to replace all the groceries: Priya plans to replace things on the way home.
• complain about the repair crew's schedule: Priya mentions the repair crew, but Priya does not complain about them.
• invite Leo to use the flat for dinner: Priya never invites Leo for dinner. The email is about checking food.

Correct Answer: can usually be kept

Why this is correct: Unopened shelf-stable juice is on the Usually Safe to Keep list.

Tips: Some answers are only in the guide. Look for the food name in every row.

Why the other options are wrong:

• must be thrown out with the milk: Juice is not on the Throw Out If Warm list with the milk.
• may go back into the freezer: This rule is for frozen vegetables with ice crystals, not juice.
• should be tasted before deciding: The note at the bottom says never taste food to decide if it is safe.

Correct Answer: Priya can buy the needed replacements on the way home

Why this is correct: Priya plans to replace those things on the way home.

Tips: The sentence right after a request often gives the reason for it.

Why the other options are wrong:

• Leo is expected to pay for the lost food: Priya plans to replace the food. Leo is not asked to pay.
• The note will show when the power failed: Priya already knows about the power cut from the fridge log.
• The building needs a list of every tenant's shopping: The email never mentions a list for the building or other tenants.
