안녕하세요? 텝스 관련 문제인데 도저히 명확하게 설명할 방법이 안 떠올라서 선생님들께 도움을 부탁드립니다.
1.(a)a:didn’t you say you are going to major in accounting?(b)b:yeah, i did, but after a few classes, it just didn’t suit me.(c)a:well, what are you going to major in then?(d)b: i have to think over it with my parents.이 문장인데요 답d)이고 think it over인데 궁금한건a)에서 주절이 과거이면 종속절에는 과거나 과거완료가 오는거 아닌가요? 그래서 you were going to major in accounting?이라고 해야 하는거 같은데 왜 저 문장이 맞는것인지요?

2.
a:whatis going on, michal? you don’t look okay today.b:yeah,i didn’t expect i_____________ stomach virus from the cheese we ate last night.a)havegottenb)willgetc)wasgettingd)wouldget

답이 d)인데 c)는 왜 안되는지요?

3.
.(a)founder and ceo of facebook, mark zuckerberg, is the world’s youngestbillionaire as of 2008. (b)he grew up in the state of new york, using computersand writing software as a middle school student. (c)his father later hired davidnewman, software developer, to privately tutor zuckerberg in writing software.(d)however, newman had to try his best as he will to stay ahead of zuckerberg’sintelligence and creativity.

에서 답이d)이고 will을 can으로 바꾸어서 그가 할 수 있는한 최선을 다해야 했다의 문장이라고 하는데 앞에 시제가 had to로 과거이니까 as he can이 아니라 as he could가 되야 하는게 아닐까요?

샘들 바쁘시겠지만 꼭 답변 기다리겠습니다. 미리 감사드리구요. 좋은 주말되세요 ^^
