Hey! Sorry, I went away from the computer for a while and I didn't see your comment. Sorry!!
Anyway, here's the answers I have for ya..
1. A) My mom and my aunt are taking us to the fair in Perry, GA.
In this sentence, "mom", "aunt", and "fair" are not proper nouns. "Perry" and "GA" are because it is the title of a place.
2. C) down the street // house
"down the street" is the phrase, and it is modifying the house, because the house is down the street.
3. D) on the floor // jacket
just like the previous question, the phrase modifies the word because the jacket is on the floor.
4. A) They should be he.
You can immediately eliminate the B, C, and D, because they make NO sense, and the "they" in the original sentence makes no sense to being with.
Sorry, I know you asked the question like an hour ago, but I hope this can still help you and anybody else that needs these answers. Baii <33
