这个奥特曼小分队太逗了~~~~~让我想起了我们"钢G连"了 如今我们连的同志们基本都700+了再忙申请了

祝贺楼主 也祝福奥特曼小分队 你们一定可以的

小虾头

恭喜lz，贺喜lz，希望自己也能考好gmat～～

请问是这道GWD原题么？谢谢
GWD28-19 Plankton
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?

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.

这题不是我考的那道。但是不能说就不是啊。这题寂静里面有啊。答案我都知道是D。

我考的那道一来就讲海藻光合作用photosynthesis怎么样怎么样。然后海边的怎么了，不是海边的怎么了，做了一个实验什么的。

后来的真的不记得了。因为好长，这题题目超长。

海藻的题目是这个嘛？

Microscopic plants called algae grow inside the top layer of sea ice in the Antarctic if enough sunlight reaches that layer of ice and enough seawater, which contains nutrients, reaches that layer after splashing onto the surface.  Even though moderate snow cover reduces the sunlight that filters into the top layer, sea ice with moderate snow cover typically contains even more algae in the top layer than does sea ice with less snow cover.
Which of the following, if true, most helps to explain the apparent discrepancy?
(A) As the weight of accumulated snow forces ice lower in the water, more seawater splashes onto the surface and seeps through the snow.

(B) Seawater in the Antarctic often contains higher concentrations of nutrients than does seawater in more temperate regions.

(C) As the air temperature around sea ice decreases during the winter, the likelihood decreases that snow will fall and thus add to any existing snow cover.

(D) The nutrients on which algae rely are common in seawater throughout the Antarctic.

(E) More sunlight filters through a layer of ice than through an equally thick layer of snow.
