2) C

A – Wrong
The text specifies that the new criteria makes planets look too hot for liquid water to form. The new criteria also makes Earth look too hot which is not true as Earth does contain water. Therefore, there is a possibility that life could exist on Kepler-22b

B – Wrong
This is actually the opposite of what is given in the text. According to the new criteria, lesser and lesser planets are habitable than previously thought.

C – Correct
The last line suggests that there is some inaccuracy in the new criteria. This statement clearly sunmmarises the content of the text and hence is the correct answer.

D – Wrong
There is no evidence given in the text that can prove this statement correct. Also, the main focus of the text is the new criteria that cosmologists now use and it is not entirely focused on Kepler-22b. This statement is too specific.
