多选题 The widely documented ______ between these two diseases has prompted scientists to undertake studies to determine if treating one can ______ the other.
【正确答案】 B、D
【答案解析】[解析] ●第二空与treating(治疗)对应；第一空表示两种疾病之间的逻辑关系。
●两空联动，若第一空填入逻辑正向，则第二空与treating同义重复；反之，则第二空与treating反义重复。
●disconnection无关，correlation相互关联，incoherency不连贯；ward off防止，bring about促成，duplicate复制。答案选BD。
