Question

【题目】After a series of researches, they finally ___ that the pollution was the leading factor contributing to the death of the creatures in the river.

A.drew a conclusion

B.came a conclusion

C.arrived a conclusion

D.made the decision

Answer 1

【答案】A

【解析】句意为“经过一系列的调查研究，他们最后终于得出了结论，即污染是河中生物死亡的主要因素”。draw a conclusion相当于arrive at a conclusion或come to a conclusion，表示“得出结论”之意，arrive和come均为不及物动词，后面不能直接接宾语，故B、C两项错误，D项表示“作出决定” 。
