问题 The primary purpose of the passage is to______ [br] According to the passage, the researchers believes that the high frequency of tooth breakage in carnivores found at La Brea was caused primarily by______

选项 A、the aging process in individual carnivores
B、contact between the fossils in the pits
C、poor preservation of the fossils after they wer removed from the pits
D、the impact of carnivores’ teeth against the bones of their prey
E、the impact of carnivores’ teeth against the bones of other carnivores during fights over kills

答案 D

解析 This question asks you what the researchers believe was primarily responsible for the high frequency of toot breakage in carnivores found at La Brea. Choice D is the best answer. According to the passage e, the explanation for the high frequency of breakage that is considered most plausible by researchers is “more contact between the teeth of the predators and the bones of the prey” (lines 20-21). Choice A is an example of demographic bias. Choice B is an example of preservational bias. Lines 9-15 of the passage indicate that researchers reject these explanations. Choice C is incorrect because preservation of fossils after removal from the pits is not discussed in the passage. Choice E is incorrect: although the passage mentions competition over kills, there is no mention of carnivores’ teeth impacting the bones of other carnivores during fights.
