【C10】______civilizations developed, greater work efficiency came to be demanded, and【C11】______tools became more【C12】______. A tool would【C13】______a function until it proved【C14】______in meeting human needs, at which point an improvement would be made. One impetus for invention has always been the【C15】______for speed and high-quality results — provided they are achieved【C16】______reasonable costs.

选项
A、convenient
B、sophisticated
C、elaborate
D、comprehensive
答案
B
解析
本题测试词义搭配。convenient意为“方便的,便利的”:sophisticated意为“复杂的,完善的”,指非常复杂、精密或尖端的;elaborated意为“详细的,精心制作的”:comprehensive意为“广泛的,全面的”。句子的主语是tools,根据前面的greater work efficiency came to be demanded(满足更高的工作效率需求)可知,应该选用B。
