### HideShow timer Statistics

It is well known that many species adapt to their environment, but it is usually assumed that only the most highly evolved species alter their environmentt in ways that aid their own survival. However, this characteristic is actually quite common. Certain species of plankton, for example generate a gas that is converted in the atmosphere into particles of sulphate. These particles cause water vapor to condense,thus forming clouds. Indeed, the formation of clouds over the ocean largely depends on the presense of these particles.More cloud cover means more sunlight is reflected, and so the earth absorbs less heat.Thus plankton cause the surface of the earth to be cooler and this benefits the plankton.

What is the main conclusion of the above statements?

a.Plakton cause the surface of the earth to be cooler.
b.It is well known that many species adapt to their environment
c.The formation of clouds depends on the presense of sulphate particles in the atmosphere.
d.The characteristic of species altering their environmentt in ways that aid their own survival actually quite common
e.Certain planktons aid in the formation of clouds

I think the answer should be D
B is not a conclusion- it is a fact which is clearly stated in the beginning of the sentence: "It is well known that many species adapt to their environment"
A, C E all relate to the plankton- sulphate-cloud example. This is used in the agument only as an example which is cited to support thw conclusion- an example cant be a conclusion in itself.

The only conclusion which is generic and not particular to example in the sentence is D

That was some real good explanation and its right. OA is "D" and you have given the OE.

The question if from the PowerScore Critical Reasoning bible. The correct answer is: this characteristic is actually quite common

Here's a good discussion of this question:

D it is.

As already stated by vivesomnium, options A, C and E refer only to the example stated in support of the conclusion. Thus, they are out.
B is actually contradicted by the entire passage. The passage is written to prove that the opposite of the traditional "knowledge" is true.
D mentions this opposite, the main conclusion of the argument.

Hi according to this explanation the correct answer is C: http://www.beatthegmat.com/powerscore-q ... 53906.html

Would you please clarify as I am convinced as well that the mean conclusion is the negation of the assumption presented .
