Are women born with(4)_____ mathematical ability? Or does society’s sexism slow their progress? In 1980, two Johns Hopkins University researchers tried(5)_____ the eternal nature/ nurture debate. Julian Stanley and Camilla Benbow (6)_____ 10,000 talented seventh- and eighth-graders between 1972 and 1979. Using the Scholastic Aptitude Test, in which math questions(7)_____ to measure ability rather than knowledge, they discovered(8)_____ sex differences.(9)_____ the verbal abilities of the males and females(10)_____ differed,(11)_____ girls scored over 500(on a scale of 200 to 800)(12)_____ mathematical ability; at the 700 level, the ratio was 14 to 1. The conclusion: males have(13)_____ superior mathematical reasoning ability.
    Benbow and Stanley’s findings,(14)_____ were published in "Science", disturbed some men and (15)_____ women. Now there is(16)_____ for those people in a new study from the University of Chicago that suggests math(17)_____ not, after all, a natural male domain. Prof. Zalman Usiskin studied 1,366 tenth graders. They were selected from (18)_____ classes and tested on their ability to solve geometry proofs, a subject requiring(19)_____ abstract reasoning and spatial ability. The conclusion (20)_____ by Usiskin: there are no sex differences in math ability.
(18)
选项 A、geometric
B、arithmetic
C、geometry
D、symmetry
答案C
解析 根据下文的tested on their ability to solvegeometry proofs(测试他们解决几何证明题的能力)，因此推断受试者是选自几何课，故选C。geometric“几何学的”；arithmetic“算术”；symmetry“对称”。
