问题 It can be inferred from the passage that scientists now generally agree that the ______.
It can be inferred from the passage that which of the following is characteristic of the pterosaurs?
选项 A、They were unable to fold their wings when not in use.
B、They hung upside down from branches as bats do before flight
C、They flew in order to capture prey.
D、They were an early stage in the evolution of the birds.
答案A
解析 由第二段最后一句对于翼龙翅膀的说明可以推知它们在行走或者站立不动(即不飞翔、不使用翅膀)时，其翅膀是呈一个倒V字形的，也就是说其翅膀收不拢，故[A]对。[B]与最后一段不符；[C]在文中没有提及；[D]与第二段第一句指出的翼龙是爬行动物不符。
