单选题
Binet used large numbers of children in his tests because he wanted to find out ______.
【正确答案】
D
【答案解析】由题干可知本题考查的是对Binet所作的各种测试的目的的判断和理解,因此可定位到第三段的倒数第二句话,and used them as a scale by which he could measure every individual,scale是standard同义词,此处意为“衡量人的智商的尺度或标准”,由此可见Binet让大量孩子参加测试的目的就是要找出一个衡量标准(standard)来,因此选[D]。[A]、[B]、[C]与文意不符,故排除。
