B. most of them are women
C. half of them are men
D. two thirds are men
题目解答
答案
D. two thirds are men
解析
本题考查对左撇子性别比例这一常识性知识点的掌握。解题核心在于了解科学研究中关于左撇子男女比例的统计数据,而非通过逻辑推理得出结论。关键点在于记忆或熟悉相关研究结果。
选项分析
- 左撇子总体比例:人群中左撇子约占10%-12%,但题目聚焦于左撇子内部的性别分布。
- 性别比例数据:科学研究表明,左撇子中男性占比显著高于女性,约为三分之二(约66%),女性占比约三分之一(约33%)。
- 选项对比:
- A、B、C选项均未体现男性占绝对优势的特点。
- D选项“two thirds are men” 正好对应研究数据,因此为正确答案。
