问题 Who first thought of using bullocks to provide energy? [br] In the sentence "This simple technology is centuries old" in Paragraph One, "This simple technology" refers to______.
选项 A、using bullocks to produce energy
B、using pumps to draw water out
C、having bullocks walk around to make the pump move
D、connecting gears of different sizes to produce electricity
答案 C
解析 本题是细节题。在文章中找到这句话，前一句和后一句分别是"它们会带动一根很沉的棍子，这根棍子又能够带动抽水泵运动起来"；"科学家们认为同样的技术可以用来发电"。可以看出这种技术和后来提到的发电是要有某种联系的。因此可以直接选C。另外，从后一句话可以知道后面要说的是利用这种技术来发电，因此排除A、D。而B项未提到小牛的作用，因此也可以选出正确答案。
