A group of paintings made approximately 15,000 years ago in a cave in the Loire River valley in what is now France depicts a number of different animals. One of the animals depicted seems to resemble the chiru, a rare antelope of the Himalayas.
Which of the following, if true, best supports the hypothesis that in painting the animal that resembles a chiru the cave artist painted a chiru with which she or he was familiar
A．There are numerous representations of imaginary animals in cave paintings of similar age.
B．Fossilized remains of a chiru, approximately 16,000 years old, have been found at the northern end of the valley.
C．The cave that contains the depiction of an animal that resembles a chiru contains stylized representations of plant life.
D．Older caves from the same region contain no representations of animals that resemble a chiru.
E．(E) The antlers of the animal in the painting are longer than those of the mature Himalayan chiru.
参考答案：B
解析： 要支持这个洞穴艺术家画的是他或她所熟悉的Chiru，就需要找一个选项表明在这个艺术家生活的那个时代，那个地方存在Chiru这种动物。从(B)选项所陈述的内容，我们很容易推出Chiru这种动物至少在1.6万年之前已经在那个地方出现，比这个艺术家创作壁画的时代早一千多年。由此分析可知(B)是正确答案。(A)和(D)对本题问题的假设构成了反对；(C)中的“植物”与本题无关；(E)引入了与本文推理无关的新的比较，因此(A)、(C)、(D)、(E)均为错误选项。
