I am confused as to why the main point of example 2 is not the first sentence or choice A. I feel like the correct answer, choice C, is just a premise of the argument.

Sorry, I meant choice D as the correct answer choice

I'm pretty confused on that too. I feel like both could equally be the main point of the argument.

Hi,
One test I like to use to find the main point is to use a because or a therefore. That is, if I am struggling to figure out if A or B is the main point, I will try to say "A therefore B" and "B therefore A" and use the one that sounds logically correct to determine what the conclusion is. Lets try this with A and D here.
We could say: it is probably within reach to alter the climate of mars therefore research into altering the climate is justified.
This makes perfect logical sense- we have a statement that something is possible, therefore we should do it.
Let's try this the other way around.
We could say: It is justified that we research altering the climate of mars, therefore it is within reach to alter it.
This makes little sense. Just because research is justified does not guarantee that it will happen, and even if the research does happen, that does not guarantee it to be possible to alter the climate of mars.
Since this test shows that A supports D rather than D supporting A, D is the main point.
