问题 By saying "let nature take its course", the biologists mean______.
According to the fifth paragraph, the scientists think the wolves’ decline in number is______.

选项 A、devastating
B、natural
C、adjustable
D、abnormal

答案B

解析 推理判断题。第五段中科学家们的观点是:公园里狼的数量已经超过其最大容纳量,因此数量会自然调节降低,疾病只是导致数量减少的一个因素而已。由此可以推断出科学家们对待狼数量减少的态度——他们认为减少是自然的。A"破坏性的",B"自然的",C"可调节的"。D"不正常的",因此B最贴切。
