问题 PASSAGE THREE
What is the author’s purpose of mentioning the medical history of European royalty in Paragraph 4?

选项

答案To confirm that inbreeding is not a good thing.

解析 根据第四段第二句可知,这些猫科动物流失了47%~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。
