In whale hunters' eyes, whales' numbers can be adjusted by
A． people's growing awareness of the balance between ecology and business
B． their theory which has been derived from life experiences
C． a flexible biological system in which all species survive
D． the change of balance between market need and the amount of whales
参考答案
D
答案解析
定位：根据题干中的信息词whale hunters定位到第三段第三句。
解析：该句意为：“……捕鲸者力图通过强调鲸鱼可以自动受保护来为他们卑鄙的勾当正名：鲸鱼一变得稀有，就没有捕捉的经济价值了，那么，人们除了停止捕鲸外别无选择。”由此可判断。捕鲸者认为当鲸鱼数量稀少时，由于不再具备市场价值会被停止捕捉，这样它们通过自然的休养生息，数量会得到恢复，因此鲸鱼的数量是可以通过市场需求调节的。故D项与文意相符，为正确答案。
