I would say:
<span>C. love endures despite family hardship
- - -
This is evident because the family is going through a very hard time, but Frankenstein doesn't understand why they are so sad when they have a home and family. He sees his reflection and sees how ugly he is, but he still can't help being good.
</span>
Answer:
3. If you want to go on the field trip. - correct answer
8. My dad .... - correct answer
9. Sighing contentedly - correct answer
14. The man who sat beside me at lunch, speaks French. A is correct answer.
15. The giggling baby - correct answer
The correct answer is A. We practiced for the debate and many arguments were rehearsed.
As you can see in this sentence, in the first part the pronoun <em>we </em>is used, and in the latter part, that pronoun just disappears and the sentence suddenly becomes passive rather than active. The shift isn't done properly - it is rather awkward. The other options are consistent - they use only one voice rather than two (like in sentence A).
