【題目】In the global economy, a new drug for cancer, ______ it is discovered, will create many economic possibilities around the world.
A.whatever
B.whoever
C.wherever
D.whichever

【答案】C
【解析】句意:在全球經(jīng)濟(jì)中,一種新的治癌藥物,無論在哪兒發(fā)現(xiàn),都將在全球產(chǎn)生巨大的經(jīng)濟(jì)利益。根據(jù) ______ it is discovered的結(jié)構(gòu)來看,句子缺少狀語,故選關(guān)系副詞,所以選C。
