Answer:
3) Coastal homes are elevated on stilts where hurricanes are common
Explanation:
I just answered this question on Edgenuity and got it correct.
It is defining.
Defining relative clause does not have a comma, while a non-defining relative clause has.
For example, if the sentence is:
The children, who hate chocolates, are uncommon.
- since there is comma in this sentence, it is non-defining.
- while if there is no comma like the question in the picture, it is defining.
This is most likely something you need to think about, its about your perspective of friendship, love, or family.
