(A) At one point of time, Galileo was the only person who believed that the earth was not the centre of the universe. - "Only"is an extreme word and it is not mentioned verbatim in the passage hence ELIMINATE

(B) A majority of scientists do not agree with the theory of evolution. - not given in the passage about how many scientists do not agree with the theory of evolution, we are just given about the fact that all the theories against evolution...

(D) When Galileo stated that the sun and not the earth was the centre of the universe, he was called insane by his compatriots. - Out of scope as we are not given what he was called by his compatriots.

(E) Everything that, at one time, seems impossible will, at some point in the future, become possible. - "Everything", an extreme word and there is prediction in this option, hence eliminate this option as well.


(C) It is difficult to prove the theory of evolution with certainty. - After eliminating, this answer choice is left which can be inferred from the statement: "from the fact that it is very difficult to prove how a group of non-living elements can combine together and give rise to life. However, just because something cannot be proved with certainty..."


Hence Option (C) is the answer.

Almost all arguments against the theory of evolution stem from the fact that it is very difficult to prove how a group of non-living elements can combine together and give rise to life. However, just because something cannot be proved with certainty today doesn’t mean that the possibility isn’t there. Remember, there was a time when almost the whole world believed the Earth was the centre of the universe until Galileo came by and proved otherwise.

The statements above, if true, best support which of the following assertions?

(A) At one point of time, Galileo was the only person who believed that the earth was not the centre of the universe.

(B) A majority of scientists do not agree with the theory of evolution.

(C) It is difficult to prove the theory of evolution with certainty.

(D) When Galileo stated that the sun and not the earth was the centre of the universe, he was called insane by his compatriots.

(E) Everything that, at one time, seems impossible will, at some point in the future, become possible.



Official Explanation



Answer: C

Let’s look at each option and eliminate:

(A) We can’t say this for sure. There may have been more people who believed so but were scared of speaking up.

(B) We know for sure that some scientists do not agree with the theory of evolution. However, whether they are in majority or not is something we do not know.

(C) The correct answer; this almost paraphrases the opening lines of the stimulus.

(D) While a lot of you may know that this is true, this cannot be inferred from the stimulus.

(E) Extreme generalization. May not be true for everything and the argument never suggests this anyway.
