Select the most appropriate option to fill in the blank. Sentence: All girls…

Correct choice: their — this is a third-person plural possessive adjective used before a noun to show ownership.

• Agreement: "all girls and boys" is a plural subject, so a plural possessive is needed.

• Form: "their" is a possessive adjective used before the noun "sweaters" (their sweaters).

• Neutrality: "their" is gender-neutral and commonly used with mixed or unspecified groups.

Why the other choices are incorrect:

• "our" refers to the speaker(s) (first person), so it does not match the third-person group in the sentence.

• "your" is second person (talking to the listener), which does not agree with the third-person subject here.

• "theirs" is a possessive pronoun used without a following noun (for example, "The sweaters are theirs"), so it cannot be placed directly before the noun "sweaters."

Example: All students must carry their bags. Similarly, All girls and boys must carry their sweaters on the trek.
