参考答案
正确答案：B
解析："Amniotic eggs and scales on the legs are just two of the reptilian features we see in birds." Choice A is true, but it is not mentioned in the passage. Choice C is not correct because the adaptations for the skeleton are described in paragraph 2. Choice D is not correct because birds have a four-chambered heart.
