问题 What can be inferred from the description of kakapo?
Bruce Robertson and his colleagues have been studying on
选项 A、the minimum weight of the females needed for breeding.
B、the peculiarities of kakapo’s breeding system.
C、the causes of uneven sex ratio existed in kakapo.
D、the protection of kakapo.
答案C
解析 推理判断题。由题干中的Bruce Robertson and his colleagues可定位至第三段首句以及第四段。首句指出：他怀疑这个性别比例不是一次意外。接着对物种的有关性别比例的知识进行介绍。在末段作者再次提到Dr. Robertson and his team，第二句指出他们的研究结果发表于Biology Letters，对性别比例进行了说明。由以上内容可以推断，该研究小组的研究课题是分析kakapo造成性别比例失调的原因。作者只在第三段第二句提到了the minimum weight they need to breed，其他各部分多次提到sex，females，males，sons，daughters，可见研究者的关注点不是weight，而是性别；同理，作者只在第三段末句提到its breeding system，其他地方没有涉及该内容；作者只在第三段第二句提到conservationists(资源保护主义者)，在全文末句指出It might even save the kakapo from extraction．但这是该项研究的意义所在，不是Dr. Robertson直接的研究目的所在。
