9 查阅

A．The WCU are interbreeding those elephants.

B．They are interbreeding species.

C．They are two genetically distant species.

D．They depend on each other for survival.

参考答案:

C解析：答案在第六段中。该段举了非洲大象为例，说明什么是cryptic species。第六段的句子“A 2001 study found the elephants were actually two genetically distinct，non-inter-breeding species”是选择C的依据。选项A不对，the WCU并没有杂交繁殖这两种象。选项B不对，短文说这两类象是非杂交物种。选项D的内容短文中找不到。
