這題答案是 (D)。  (學習出版 高三英文克漏字測驗 – p.15 北一女中試題)

這題的重點在連接詞：

1.   若使用連接詞[ so ]，[ A子句: researchers drive special heavy-duty vehicles near tornadoes]與[ B子句: they record wind spends and other meteorological data ]意思不連貫。

2.   若使用連接詞[ that ]，連接詞[ that ]前面不能有[ , ]。

3.   若使用連接詞[ which ]，連接詞[ which ]可以修飾前面的先行詞或子句，當作所引導子句的主詞或受詞。但這裡它作所引導的子句已經有主詞[ they ]與受詞[ wind speeds and other meteorological data ]，所以不可能是[ which ]。

4.   只有( D )是適當的答案。
