A.I. Explanation:

Correct Answer: the cooked rice has passed the discard limit

Why this is correct: Cooked rice is a discard item after more than two hours above the stated temperature. The logger records four and a half hours, so that condition is met.

Tips: Apply the measured condition rather than treating a general estimate as a guarantee.

Why the other options are wrong:

• the cooked rice can stay if it looks normal: The guide does not allow appearance to cancel the recorded temperature condition.
• every unopened item must be thrown away: The keep list includes some items. Being unopened does not make every item a discard item.
• the four-hour fridge estimate still guarantees the rice: The estimate describes how long an unopened fridge may stay cold. The logger shows what happened here.

Correct Answer: the block of hard cheese and whole apples

Why this is correct: Both a block of hard cheese and whole fruit are in the keep list. The other pairs each include a food that meets the discard rule.

Tips: Check both members of a pair; one suitable item does not make the whole answer correct.

Why the other options are wrong:

• the cut melon and milk: Both cut fruit and milk are in the discard group.
• the yogurt and whole apples: The whole apples may be kept, but the yogurt must be discarded in these conditions.
• the cooked chicken and block of hard cheese: The cheese may be kept, but cooked chicken is meat in the discard group.

Correct Answer: may go back into the freezer

Why this is correct: The peas are frozen vegetables with ice crystals. That meets the guide's condition for refreezing them.

Tips: Keep the fridge rule and the frozen-vegetable rule separate.

Why the other options are wrong:

• must be kept only at room temperature: The guide allows refreezing, not storage at room temperature.
• must be discarded with the rice: The rice rule applies to its recorded warm conditions. The peas meet a separate refreezing condition.
• are safe only if the bag was unopened: The guide names ice crystals, not an unopened bag, as the relevant condition.

Correct Answer: the food's flavour

Why this is correct: The guide specifically warns against tasting food to judge safety. The rice seeming normal does not change that warning.

Tips: Distinguish a prohibited taste test from the evidence the guide actually uses.

Why the other options are wrong:

• the temperature log: The log supplies useful information about temperature exposure.
• how long the food was warm: Time spent warm is part of the discard rule.
• the kind of food involved: The food category matters because the guide has different keep and discard groups.

Correct Answer: keep the cold-storage doors shut unless necessary

Why this is correct: The guide says to keep fridge and freezer doors closed unless opening them is necessary during a power cut.

Tips: Find the instruction for the next outage, rather than applying only the after-outage food rules.

Why the other options are wrong:

• move every frozen item onto the counter: Moving every item out would not follow the closed-door instruction.
• leave the fridge open for the repair crew: Leaving the door open is not the stated precaution.
• check each shelf repeatedly while waiting: Repeated shelf checks conflict with keeping the doors closed unless necessary.

Correct Answer: To arrange a careful check of food while she is away

Why this is correct: Priya is away and asks Leo to inspect the food using the guide. Buying replacements comes later and is her own task.

Tips: Separate the main request from background information and later plans.

Why the other options are wrong:

• To ask Leo to replace all the groceries: She says Leo does not need to buy anything himself.
• To complain about the repair crew's schedule: She mentions the repair crew to plan for another cut, not to complain.
• To invite Leo to use the flat for dinner: She asks for a food check, not a dinner visit.

Correct Answer: Priya can buy the needed replacements on her return

Why this is correct: The note will tell Priya which items she needs to buy on her way home.

Tips: Read the sentence after a request to find why the writer needs it.

Why the other options are wrong:

• Leo is expected to pay for the lost food: She does not ask Leo to pay or shop.
• The note will show when the power failed: The outage and temperature details are already available from other records.
• The building needs a list of every tenant's shopping: The message concerns her own flat, not a building-wide shopping list.

Correct Answer: She wants to avoid waste without ignoring safety rules

Why this is correct: Priya hopes some shopping can be saved, but she still follows food-specific rules and will check advice for uncertain items.

Tips: Look for both the writer's aim and the limit she places on achieving it.

Why the other options are wrong:

• She is relaxed about using anything that looks normal: She follows the guide rather than accepting food just because it seems normal.
• She wants Leo to decide without consulting any guide: She explicitly asks Leo to check the guide.
• She is certain all the food has been lost: She says some food may be saved, so she has not written everything off.
