A.I. Explanation:

Correct answer: labels

Explanation: The word 'labels' fits grammatically as it is a plural noun that refers to the paper shipping items that need to be removed. It aligns contextually with the instruction to ensure envelopes are clean and dry, indicating that any attached labels should be removed before shipping.

Meaning: 'Labels' are tags or stickers that provide information about the contents or destination of a package.

Wrong options:

• brushes: 'Brushes' are tools used for painting or cleaning, which do not relate to shipping envelopes and are irrelevant in this context.
• scissors: 'Scissors' are tools for cutting, but they do not fit as they are not something that needs to be removed from the envelopes.
• process: 'Process' refers to a series of actions or steps taken to achieve a particular end, which does not fit as it does not refer to a physical item that can be removed.
• cables: 'Cables' are wires used for electrical connections, which are unrelated to shipping envelopes and do not fit the context.
• prices: 'Prices' refer to the cost of items, which is not relevant to the action of removing something from shipping envelopes.

Correct answer: process
