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

Option A - INCORRECT.
This option is just an example sighted to give more information on the assumption that, only the most highly evolved species alter their environment in ways that aid their own survival. Therefore this option is not the conclusion base on the statement.
Option B - INCORRECT.
It is well known that many species adapt to their environment, but only the young species does this.
Option C - INCORRECT.
This option has picked some part of the information given, However it does not worth to be a conclusion on the statement given.
Option D - CORRECT.
This option stands to be the most suitable conclusion of the statement. It is well known that many species adapt to their environment, meanwhile, only the most highly evolved species alter their environment in ways that aid their own survival. However, this characteristic is actually quite common, an example of such species is a certain plankton who generate a gas that is converted in the atmosphere into particles of sulphate. This process causes the surface of the earth to be cooler and this benefits the plankton and also aids their survival.
Option E - INCORRECT.
Certain plankton aid in the formation of cloud is an example sighted in the statement and not a fact to represent how other species create their own atmosphere for survival.

Let us look at the step by step approach to this question.
The first step would be identify the Question type : From the word "Conclusion" given in the argument, we come to know that the question seeks an option that is supported by the information given in the argument. Hence this can be categorized as an Inference Question.
The obvious step to solve an Inference question would be to first check for the obviously wrong answers and eliminate them. This also means you can eliminate answer choices that are not always true.
A - Not true as per the information given as there is no relationship between Planktons and earth's temperature directly.
B - Very generic statement. There could be species that do not adapt at all.
C - This option tends to make us believe that sulphate particles are the only reason why clouds are formed - This is incorrect.
D - OA
E - This is just an example. Again, it may not be the planktons directly. It is planktons plus the other factors.
Hope that helped - All the best
