Answer 1

The father thought it worthwhile to invest in their daughter's education____ the mother considered it a waste of time.
A,however B yet C if D while
并且说说为什么不选其它?
答：选D
从属连词一般通过翻译（理解句子的逻辑）来判断.while表示对比,译作“而” if表示“条件”译作“如果”.
父亲认为在女儿的教育上投资是值得的,而母亲却认为这是在浪费时间.（还好没说是浪费钱）.
however 作副词解时有“然而”的意思,表示转折.但要另起一句,且后面要有逗号隔开,不隔开,会当作从属连词引导让步状语从句了.（并列连词but就不要）.yet作为副词也不能引导从句,且常用于句后.
补充：yet是可以作并列连词（还在演变过程中）.《Longman》已改入：
conj.but even so; but:strange yet true | She's a funny girl,(and/but) yet you can't helpliking her.
既然这样,用yet也不算错,但考虑到最佳答案只有一个,还是选D吧.
