2. Interpret Rereadlines 17-20. When Rachel says that growing old is "like an onion," she is using a simile, a comparison that uses the word like or as.
What other similes does she use in lines 17-20, and what meaning do all
the similes convey?

I don't know any of the other similes because I have no idea what poem you read but here is the answer to what growing old like an onion could convey:

Onions are layered, as they grow more and more layers grow. This could mean that as Rachel grows, she gains more layers of knowledge and experiences and they keep layering over time as she grows.

d when mathilde realizes she has lost the necklace

ok so it would be d because that would catch attention and make them what to read it.
