一道GWD Planktongenerally thrive in areas of the ocean with sufficient concentrations ofcertain nitrogen compounds near the surface, where plankton live. Nevertheless, some areas, though rich inthese nitrogen compounds, have few plankton. These areas have particularly low concentrations of iron, andoceanographers hypothesize that this shortage of iron prevents plankton fromthriving. However, an experimentalrelease of iron compounds into one such area failed to produce a thrivingplankton population, even though local iron concentrations increasedimmediately. Which ofthe following, if true, argues most strongly against concluding, on the basisof the information above, that the oceanographers’ hypothesis is false? A. Not all of the nitrogen compounds that aresometimes found in relatively high concentrations in the oceans are nutrientsfor plankton. B. Certain areas of the ocean support an abundanceof plankton despite having particularly low concentrations of iron. C. The release of the iron compounds did notincrease the supply of nitrogen compounds in the area. D. A few days after the iron compounds werereleased, ocean currents displaced the iron-rich water from the surface. E. The iron compounds released into the areaoccur naturally in areas of the ocean where plankton thrive. 这个问题argue against ....is false 到底是赞同呢 还是反对呢 我连问题都没读明白必然做不出。。。谁帮我翻译一下 顺便解答下这个题吧
