Which of the following, if true, argues most strongly against concluding, on the basis of the information above, that the oceanographers’ hypothesis is false?
A: Not all of the nitrogen compounds that are sometimes found in relatively high concentrations in the oceans are nutrients for plankton.
B: Certain areas of the ocean support an abundance of plankton despite having particularly low concentrations of iron.
C: The release of the iron compounds did not increase the supply of nitrogen compounds in the area.
D: A few days after the iron compounds were released, ocean currents displaced the iron-rich water from the surface.
E: The iron compounds released into the area occur naturally in areas of the ocean where plankton thrive.
CD的參考答案是D
可是我選了E說
我的想法
要反駁海洋學家的推論(就是反駁this shortage of iron prevents plankton from thriving)
如果D 海浪會把鐵給帶走
不是反而因為海浪帶走鐵 造成鐵短缺 所以浮游生物不能繁榮 不就間接加強了這個推論嘛??
請各位NN幫忙指點迷津
thx
