    A land free from destruction, plus wealth, natural resources, and labor supply—all these were important【C1】______ in helping England to become the center for the Industrial Revolution. But they were not enough. Something else was needed to start the industrial process. That "something special" was men—【C2】______ individuals who could invent machines, find new【C3】______ of power, and establish business organizations to reshape society.
    The men who【C4】______ the machines of the Industrial Revolution came from many back grounds and many occupations. Many of them were more inventors than scientists. A man who is a【C5】______ scientist is primarily interested in doing his research【C6】______. He is not necessarily working so that his findings can be used.

He may try to solve a problem by using the【C7】______ of science or by experimenting through trial and error. Regardless of his method, he is working to obtain a【C8】______ result: the construction of a harvesting machine, the burning of a light bulb, or one of many other【C9】______.

【C4】
选项
答案C
解析 who引导的定语从句中缺少谓语动词，故空格处应填入动词。下一句Many of them were more inventors than scientists“他们中的许多人与其说是科学家．不如说是发明家”是对空格所在句的The men的进一步说明，由此可以推断先行词The men和定语从句中的the machines之间是发明与被发明的关系，填入词库中的created“创造”符合语义。
