(单选题)

Human ingenuity was initially demonstrated in ______.

A.the use of machines to produce science fiction

B.the wide use of machines in manufacturing industry

C.the invention of tools for difficult and dangerous work

D.the elite’s cunning tackling of dangerous and boring work

参考答案：C

参考解析：

细节理解题。根据文章第一句“Since the dawn of human ingenuity, people have devised ever more cunning tools to cope with work that is dangerous, boring, burdensome, or just plain nasty.”可知，人类利用自己的智慧发明了很多狡猾的工具来做自己不愿意去做的工作，但并没有强调“the elite”，因此排除D，而A、B两项都不符合题中“initially”这一要求，故选C。
