问题 Fossil bones of the huge herbivorous dinosaurs known as sauropods were first discovered and studied between 1840 and 1880, providing evidence for the gargantuan dimensions of the adults. The shape of sauropod teeth suggested what they ate. But
line aside from trackways, or series of fossilized footprints—which established that sauro-
5 pods at least occasionally lived in herds—fossils incorporating direct evidence of other behavior, such as reproductive behavior, have been almost nonexistent. Because no modern land animals even approach sauropod size, scientists have also lacked a living analogue to use as a guide to possible sauropod behavior. Until the recent discovery of fossilized sauropod nesting grounds, scientists were thus uncertain whether sauropods
10 laid eggs or gave birth to live young.
Description
The passage outlines what was learned about sauropods after the discovery of their fossilized bones in the nineteenth century, including what has been inferred about their behavior from the fossil record. [br] Which of the following can be inferred from the passage regarding the evidence provided by sauropod teeth?
选项 A、The teeth allow inferences to be made about sauropod social behavior.
B、The shape of the teeth indicates that sauropods were herbivorous.
C、The teeth have no resemblance to those of any modern land animal.
答案 B
解析 Choice B is the only correct answer.
Choice A is incorrect: the passage mentions that fossilized footprints permit the inference that sauropods exhibited herd behavior, but there is no indication that this or any other social behavior can be inferred from sauropod teeth.
Choice B is correct: the passage states that sauropods were herbivorous(feeding on plants)and that "the shape of sauropod teeth suggested what they ate."
Choice C is incorrect: the passage says that there are no modern land animals similar in size to sauropods, not that there are no such animals with similar teeth.
