Steel is widely used in our daily life because
A、it doesn't bend and rust,like iron
B、it has the magic power to break things
C、in the mid-19th century,it became central to our lives
D、technology has made it possible to produce it cheaply
【正确答案】：D
【题目解析】： 细节判断题。题干问钢铁为什么会在日常生活中广泛使用。文章第五段在介绍钢铁时讲到钢铁的特性，并提到古罗马时期就开始使用钢铁。但十九世纪中期工业化生产、造价低廉的钢铁才成为生活必不可少之物（but once inventors created a process for producing steelcheaply at industrial scale in the mid-19th century, it became central to our lives）。可见D选项的内容最符合文意，因此，选项D是正确答案。
