I agree that A is too strong. However, if we choose B, the conclusion has nothing to do with the last phrase "using a technique called "acid-etching" scientist found that the meteorite contained fossilized remains of single-cell life forms." Hence, I think that the reasoning is not very logic.

Can anyone explain me?

You are right, it doesn't follow a chain of logic. This is more a series of facts.

For example:
"Tim likes blue things. The car is blue. The house is red"

What is a possible conclusion here? Need it involve the last fact? No.

bb Sajjad1994 KarishmaB MartyMurray Can you please help in how to effectively differentiate between week choices and choices that are inherently mentioned in the argument.
There are questions, where the options given to the question are just in-direct or passive voice of the info given in the argument, which makes it not the correct choice for selecting. I faced the same issue here while solving this, where option B was too readily conveying the info given in the argument.
Please guide here.

You have to understand how to answer different CR question types and what they require in the conclusion.
The conclusion is something that has to be pretty accurate and solid.

E.g. choosing A that there must life on mars because the meteorite contained a life cell is too far of a conclusion. It requires a few hops and assumptions. E.g. maybe Mars had life a long time ago but not anymore and it just stayed on the meteorite, so we cannot conclude there there is life. We can conclude that there may have been life at some point on mars if this meteorite came from the planet. ....

I think there is a difference between 'life form' and 'single -cell life form'
For me it was a choice between B and E.
B is a better answer.

Its possible that single cell life form was deposited after meteorite landed in antartica. Only thing scientist can hypothise is that probably meteor came from Mars. So B

a) The fossilized remains indicate that life exists on Mar
-- fossil remains means there was once life, and nothing else.
b) The scientists have evidence to support a hypothesis that the meteorite came from mars.
-- Correct!
c) The meteorite represents a substantial step forward in human knowledge of the development of life in the solar system.
-- this cant be said, 'Shell building', hence wrong.
d) undiscovered meteorites currently exist in Antarctica
-- cant be said, they only found one.
e) "Acid - etching" is necessary to confirm the existence of fossilized remains in meteorites.
-- others may also exist.

IMO B
If you choose A, you must assume that the fossil remains found in this meteorite actually didn't attack to this meteorite after it travel to the earth.

Definitely B! Shortlisted the answer choices to B and E, but E is a bit too extreme...so went with B..

How can it be B? To date they have not found, but that does not mean that
not finding = attributing it what is found in a limited sample

Am I looking at it the wrong way?

A detailed lab analysis of a meteorite recently discovered in Antarctica revealed that the meteorite has geological characteristics common to the planet Mars. To date, scientists have not found these characteristics anywhere other than on Mars.

(B) The scientists have evidence to support a hypothesis that the meteorite came from Mars.

Since they did not find these characteristics anywhere else, they ASSUME that the meteorite is from Mars. An assumption is not an evidence. That I have seen pizza only when I was in Italy on holiday does not mean that I have an evidence that pizza is an Italian food. Can anyone explain to me why the answer is B? This CR example has no correct answer, in my opinion.

The statement above, if true, best support which of the following as a conclusion?

a) The fossilized remains indicate that life exists on Mar -Life "might" exist would have made it a correct choice
b) The scientists have evidence to support a hypothesis that the meteorite came from mars. -Correct
c) The meteorite represents a substantial step forward in human knowledge of the development of life in the solar system. -out of scope
d) undiscovered meteorites currently exist in Antarctica -out of scope
e) "Acid - etching" is necessary to confirm the existence of fossilized remains in meteorites. -it is just one technique

Option B it is ... If you chose option A , just remember that presence of single cell life form only means that life once existed. It does not imply that life exists right now !Option E is too extreme.

Exactly my thought. Can someone explain why last premise is not considered in the conclusion?

It seems to me like B is just restating the 2nd sentence, but the question is asking for a conclusion. I didn’t think restating is the same as a conclusion. Can anyone explain?

I get it why A is wrong since we cannot be sure but how is B an answer? aren't we assuming that on Mars these single celled organisms existed/exist? evidence (fossil remains)? how do we know that if it did exist? how does this evidence reflect that meteorite came from mars? Though I agree all other options are a NO NO but still B doesn't make sense to me.
