질문 내용 :  다음을 읽고 물음에 답하시오.
I am incapable of taking anybody’s word as it is—I have to see for myself. If I read a quoted source in a book, I have to read the source (a)[from which/which] the quote is taken. If that source quotes someone else, I am motivated to (b)[find/finding] the original. If I ever finally get to the originator of an idea, I am driven to (c)[study/studying] the life and methods of that person. If possible, I try to discover the observations (d)[what/which] led the person to a particular conclusion. This is time­consuming and tiring, no question about it; but it is the only way that satisfies me. (e) , I am curious.
