题目：
Plankton generally thrive in areas of the ocean with sufficient concentrations of certain nitrogen compounds near the surface, where plankton live. Nevertheless, some areas, though rich in these nitrogen compounds, have few plankton. These areas have particularly low concentrations of iron, and oceanographers hypothesize that this shortage of iron prevents plankton from thriving. However, an experimental release of iron compounds into one such area failed to produce a thriving plankton population, even though local iron concentrations increased immediately.
Which of the following, if true, argues most strongly against concluding, on the basis of the information above, that the oceanographers' hypothesis is false?
选项:
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.
答案:
D
提问：
原文的逻辑链说：P通常在N丰富的地方生长的好，但是尽管如此，有些地方有N但没P。这些地方的特点是有铁，所以O这些人就假设缺铁是P不能生长好的原因。题目要求选一个反对假设是错的，也就是说选一个支持O这群人的假设的
读完选项之后全杀了：A说不是所有的N对于P来说都是有营养的，无关；B 有的地方没铁但P多，驳斥 C铁没有增加N，无关，D 几天之后有铁，海水把铁弄没了，无关；E：P生长的地方有铁，有关留着了；相对于其他的好点
