问题 It can be inferred from the first paragraph that ______.
The sales of robots have been on the rise chiefly because ______.
选项 A、the technology robots use is really advanced
B、robots greatly increase the efficiency in factories
C、robots are becoming economically available
D、most car factories around the world need robots
答案C
解析 由题干中的The sales of robots have been on the rise定位到原文第二段第二句Demand is increasing as prices fall；a robot sold in 2007 cost less than a fifth of an equivalent robot sold in 1990，for example．[精析] 目的原因题[考频：24]。该句说得很清楚：需求随着价格的下降而增加。那么机器人销量增加的主要原因就在于价格的降低，也就是说机器人已经在价格上比较划算了。故C)“机器人的价格正变得合理”与之相符．为正确答案。[避错] A)“机器人运用的技术确实进步了”在原文没有涉及，排除；B)“机器人大幅度提升了工厂效率”在原文也没有提及；原文只是说“在日本、德国和意大利的汽车工厂，每十个生产工人就配有至少一台机器人”；D)扩大化到了世界大部分工厂，与文意不符合．故排除。
