Passage One
A. Dogs have a natural instinct to guide the blind.
B. Horses have a natural instinct to return home.
C. Guide dogs sometimes may not obey their masters.
D. Racing horses are less smart than the other horses.
题目解答
答案
C. Guide dogs sometimes may not obey their masters.
解析
本题考查对阅读理解文章细节的把握，需要结合选项与原文内容进行匹配。关键点在于理解“自然本能”与“实际行为”的区别。选项C强调“导盲犬有时可能不听主人的话”，这需要关注文章中是否提到导盲犬在特定情况下会基于自身判断而非本能行动。
选项分析
A. Dogs have a natural instinct to guide the blind
- 若文章提到导盲犬通过“训练”而非“本能”帮助失明者，则此选项错误。
B. Horses have a natural instinct to return home
- 若文章未提及马的归家本能，或明确说明此本能不普遍，则此选项错误。
C. Guide dogs sometimes may not obey their masters
- 正确选项。若文章举例说明导盲犬在紧急情况下（如感知危险）会自主行动，而非完全服从主人指令，则此选项符合文意。
D. Racing horses are less smart than the other horses
- 若文章未将赛马与其他马的智力作对比，或强调赛马的专注而非“更笨”，则此选项错误。
