问题 The ______ of such I. Q. tests full of questions on American culture was not questioned at that time.
选项 A、significance
B、validity
C、efficiency
D、justification
答案B
解析 本题是说只对美国文化进行提问的智商测试的有效性在当时并没有受到置疑。 B项“validity有效性，正确性”符合题意。如：the term of validity(有效期)。其他三项“significance重要性；efficiency效率，功率；justification认为有理，认为正当”都不正确。
