People usually devise tools to (22) for natural deficiencies. For example, people invented weapons to defend (23) from physically superior (24) . But (25) is only one incentive for inventions. People also invent (26) tools to (27) certain established tasks more efficiently.

One impetus for invention has always been the (35) for speed and high-quality results--provided they are achieved (36) reasonable costs. Stone pebbles were sufficient to account for small quantities of possessions, (37) they were not efficient enough for performing sophisticated mathematics. However, beads arranged systematically evolved into the abacus.

选项
A、Since
B、If
C、Now that
D、As
答案
D
解析
本题测试语法。since引导时间、原因状语从句,引导时间状语时其主句通常用完成时态:if引导条件状语从句;now that引导原因状语从句;as引导原因、时间状语从句以及定语从句,引导时间状语时意为“随着”。civilizations developed与greater work efficiency came to be demanded是伴随性动作,所以应该选D。
