问题 PASSAGE THREE
What is the author’s purpose of mentioning the medical history of the European royalty in Para. 4?
选项
答案To confirm that inbreeding is not a good thing．
解析 根据文章第四段第二句可知，这些猫科动物流失T47％~70％的基因流，正如我们通过欧洲皇家的病史所知的那样，近亲繁育不能创造出最健康的血统，由此可知，此处提到欧洲皇家病史是想进一步说明近亲繁殖不是最健康的选择，故“To confirm that inbreeding is not a good thing．”为正确答案。
