请问有没有GWD TN 1-24 套逻辑讨论贴？？很多题搞不明白，又搜不到相一致的讨论贴

谢谢MM，我搜到的也只是这个，但是找不到我想要看的题，比如 ：GWD TN-19 GWD28-Q19:

选D, 但是我做了很久，感觉比较绕（本人比较愚钝），所以想看讨论贴，如果遇到这种题，有没有较快的做对题的办法，可是没看到相关讨论贴，帮忙~~

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.

The oceanograther’s hypothesis : the shortage of iron is not the reason that prevent plankton from thrivingà提干问哪个选项说明oceanograther’s hypothesis 是错的—〉就要证明 the shortage of iron is the reason  that prevent plankton from thriving.

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.
