Choose the sentence that would serve as the most effective topic sentence for the paragraph. a) people should quit working for major corporations. b) employees are frustrated with long commutes to work. c) people should take the bus or train to work because it is a more environmentally friendly way of commuting. d) as highways become more congested and commute times becoming increasingly longer, companies should consider flex-time or satellite offices.

Personally, I'd say the correct answer is to learn about the human experience during internment.
I don't think A is correct because not all of these questions were only about her mother, but about her family and other families in general. History books are not mentioned and we don't see an unusual point about their internment, which is why I believe the interviewer is only curious about what it was like then.
