It is uncertain____side effect the medicine will bring about，although about two thousand patients have taken it.
A．thatB．whatC．howD．whether
B
B【命題立意】考查主語(yǔ)從句的引導(dǎo)詞。
【解題思路】句意為：盡管大約有兩千名病人服用過(guò)這種藥物，但是，它會(huì)帶來(lái)什么樣的副作用還不確定。side effect 意為“副作用”，還原主語(yǔ)從句中的主干是the medicine will bring about  side effect。故選擇what，what在本題中形容詞，意為“什么樣的”，起修飾作用。
