Question

which sentence uses this meaning of peer?
peer noun someone of the same age
aubrey is my peer, but she looks much younger than i do.
lets peer around the corner to make sure no one is coming.

Explanation:

We need to find the sentence where "peer" means "someone of the same age". In the first sentence, "Aubrey is my peer" uses "peer" as a noun referring to someone of the same age (even though she looks younger). The second sentence uses "peer" as a verb meaning to look closely or carefully, which doesn't match the given noun meaning.

Answer:

Aubrey is my peer, but she looks much younger than I do.
