Answer:
As a high schooler myself I would personally ask what classes should you take first because obviously you would want to get your core classes out of the way and then take your electives after because for some schools or it may be all schools you can graduate early if you get all your core classes done. I would also ask which classes are the hardest.
Explanation:
I'm not sure how to understand this question...
But if the question is asking about what the cat did, and how you would explain it?
or if they meant to explain that sentence...
if they mean to explain the sentence itself, I would say the answer is

But is they meant to tell about the next chapter, I would ASSUME the answer to be
B
