Why is a survey better than a case study to find out people's preferences for wearing certain shoe brands?
surveys will give you 100 percent accuracy in guessing people's preferences.
case studies focus on too few people to get the results you want.
case studies are only interested in values, not attitudes or opinions.
surveys allow many people to report their personal opinions.

I would have to say B and D are very close, but I would say D in this scenario

Yeah, the answer is definitely b.assuming that you're a high school student or middle school student, you probably don't need your parents' to pick out your clothes anymore. and i don't know how it works at other schools, but i know that at my high school, you don't get to pick the book you read for an english assignment. your teacher picks that. the decision of what after-school job i should get, i would definitely make with from my parents and other people that i trust. ultimately, the decision is up to me, but i would need advice from people who are more experienced.
