问题 The scientists have absolute freedom as to what research they think it best to ______.

选项 A、engage
B、chase
C、seek
D、pursue

答案D

解析 语义连贯题。所填词可用作及物动词,并可以和research搭配,[D]pursue“从事或忙于(某事)”,符合句意,所以[D]为答案。[A]engage常和in一起连用,表示“忙于或从事某事”;[B]chase“追求,追逐,追捕”着重于追赶者的迅速和决心,其动机不是很友善的,但也可能是出于好玩或取乐;[C]seek“追求,追寻”指寻找方向、地方、工作或人,和research不搭配。
