【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.

A、trailed
B、traced
C、trapped
D、tested
答案
B
解析
本题测试词义搭配。trail意为“跟踪,追踪”,指“追随……的足迹或气味”: trace意为“追溯,探索”,指“尽力发现某些已出现或发生的事所留下的记号、痕迹”,通常与to搭配使用:trap意为“诱捕,设陷阱”;test意为“测试,检测”。根据后面的to the development可知,应该选用B。
