Hmm... actually, IMO, b. Here's why:
[spoiler]A - definitely false. We aren't even sure that the meteorite is from Mars. We only think it is.
B - makes sense. We can hypothesize that this is true.
C - totally out of scope.
D - we could have found the last meteorite in Antarctica. (unlikely, but still possible)
E - there could be other methods as well... why only acid-etching?

analysis of a meteorite
Source: Beat The GMAT — Critical Reasoning |
We are asked to find a conclusion, B is not a conclusion, if we say B is conclusion then the point about single cell life is irrelevant to the argument.
On the other hand A says we are sure that life exists now in Mars, fossilized remains could have been of 100 million years old...
So IMO C..... which sounds like a conclusion....
Thanks

I am going with A!! My reasoning is, Meteorites and Mars share common geological characteristics.gtvisa2002 wrote:We are asked to find a conclusion, B is not a conclusion, if we say B is conclusion then the point about single cell life is irrelevant to the argument.

Now that Metorites have found to have life forms. SO it leads to believe that Mars also contains Life forms!
I totally agree with you. Let me put it this way,gmatmachoman wrote:I am going with A!!

So from option A, we confirm that life exists in Mars.
Option C says we are moving a step towards confirming this.
From the information given we can safely conclude that we are moving forward, but we can't say we found evidence.
I am not trying to say C is the answer. What I am saying is, C makes more sense.
Correct me if I am wrong.
Thanks

Actually, I was looking explanation for E.
I got it. Why only method (acid-etching) is necessary? There can be some other method as well.
Now I reached to OA.
Thanks
Can someone please elaborate how we are getting B.
On what basis are we eliminating the other options.How does the last sentence of the stimulus(acid-etching) help in reaching the conclusion B.The answer A looks a better conclusion than B.

A - too far fetched. This is an example of an extreme answer choice. EliminateGmat_War wrote:Can someone please elaborate how we are getting B.

B - Correct. Discovery is just an evidence on basis of which scientists are forming various theories.
C - It could also be a small step. No evidence to support this statement. Eliminate
D - Nothing to support this statement in the Stimulus - Eliminate
E - There could be other methods that can do the same job. Acid Etching could just be one of the effective methods. Eliminate.
I still did not get B.I could not understand why finding of the asteroid could be evidence that this metroid came from Mars. critics may hitback that just because we have not found 'such' characteristics anywhere does not mean this asteroid has come from Mars. It could be equally possible that this asteroid could have come from an unknown planet X, whose characteristics are similar to mars.
Finding this asteroid could only be another hypothesis, or at best one step closeer to the evidence about its origin from mars, not an evidence.
