12.Very popular from 1900 until the 1920's, the renewed interest in ceiling fans began when the energy crisis in 1974 forced homeowners to look for alternative methods of heating and cooling.
(A) Very popular这种形容词放在开头肯定不对，如果时v-ed 或者是v-ing才可以 from 1900 until the 1920's, the renewed interest in ceiling fans began
(B) The renewed interest in ceiling fans, which were very popular from 1900 until the 1920's began（which此处不是指代不清吗，这里不是应该就近指代fans吗？？？
象这种A in B，which +v,此中的which到底指代谁啊？？,没有谓语,就是指代A??)

我总是觉得此中的which指代ceiling fan有些理解不通,
看了你的解释觉得也比较合理,不过还是需要想一想!
18. Stable interest rates on long-term bonds are the financial market's vote of confidence in the Federal Reserve keeping in control of inflation.
(A) in the Federal Reserve keeping in control of inflation
(B) that （难道that引导的是宾语从句吗）the Federal Reserve will keep inflation under control（under control这个确实比较idiomatic）
(C) for the Federal Reserve, that it would keep control of inflation
(D) that inflation will be kept control of by the Federal Reserve
(E) that inflation would be kept control of by the Federal Reserve
A are B of C that ?? that 指代什么？答案应该是指代A？？
还能告诉我这个that的指代嘛,我是不是比较贪心啊

18. His studies of ice-polished rocks in his Alpine home-land, far outside the range of present-day glaciers, led Louis Agassiz in 1837 to propose the concept of an age in which great ice sheets had existed in now currently temperate areas.
(A) in which great ice sheets had existed in now currently temperate areas
(B) in which(修饰谁，代指什么?我不明白，如果是when还可以说代指an age) great ice sheets existed in what are now temperate areas
(C) when great ice sheets existed where there were areas now temperate
(D) when great ice sheets had existed in current temperate areas
(E) when great ice sheets existed in areas now that are temperate
b中的inwhich又是指代什么,我这些一直都是疑惑?
请各位XDJM帮忙解答一下

这里的WHICH就是就近指代ceiling fans。
我认为一般情况下which ，that 都要就近指代。特殊状况要指代前面名词，需要在谓语部分体现出来。
