Read the following sentence: "The sky began to grow dark, setting in for the night. It reminded me of the year I spent in Italy." What word is the allusion? 1) sky
2) night
3) Italy
4) Rome
5) no allusion

You don't have enough information to pick a sure choice. Pick 2 but it might be 1.

Explanation:

For me, it would have been dark. Since that word isn't offered, I would pick night.

There definitely is an allusion of some kind. He is reminded of something.

Italy is mentioned, but I think we are to assume it could have happened anywhere. Rome is never mentioned.

Sky is likely a good choice, and it might even be the answer, but I think a better choice is night.

yes he does : )
