问题 Why did Wilson regard the depletion of rain forest areas as the greatest extinction since the end of the age of dinosaurs?
选项 A、The rain forests’ survival is questionable.
B、It will become warmer and warmer with the depletion of rain forests.
C、Many wild animals will become extinct as a result of the depletion of rain forests.
D、The writer did not give his explanation.
答案D
解析 细节题。文中提到哈佛大学的生物学家E.O.Wilson把热带雨林的枯竭称为“自恐龙时代结束以来最大的灭绝”，但他做出这样评论的原因文中并没有进行解释，故D为正确答案。A具有强干扰性，但细看仅是问题的现象，而不是原因。
