I believe the correct choice of answer would be A. Hope this helps!
A house makes me think about my family because that's were we live. well not for long because were moving. moving makes me think of my best friend who moved away. Away makes me think about how far from my other friends I'll be. This makes me upset.
Answer:
The second one: You are, if I'm not mistaken, a good person for this experiment.
Explanation:
The first sentence, "You are, if I'm not mistaken a good person, for this experiment." does not have a comma after "mistaken", where there should be one. After "a good person", there should not be a comma.
The answer would be true!
I hope this helps!
