Whats wong with C?

It is just a paraphased part of the stimulus:
The axis of Earth’s daily rotation is tilted with respect to the plane of its orbit at an angle of roughly 23 degrees. That angle can be kept fairly stable only by the gravitational influence of Earth’s large, nearby Moon. Without such a stable and moderate axis tilt, a planet’s climate is too extreme and unstable to support life. Mars, for example, has only very small moons, tilts at wildly fluctuating angles, and cannot support life.

Experts please explain.



Even I was looking for C as the answer but soon realized that statement mentions that Without such a stable and moderate axis tilt, a planet’s climate is too extreme and unstable to support life. but does not mentiones that this is not the only reason to support life so if any other planet is having stable and moderate axis tilt but does not have other supportive condition then it does not help.

IMO D

Did you notice that in B it says Earth's orbit. Moon in Earth's orbit is not not correct at all....

If the statements above are true, which one of the following must also be true on the basis of them?

(A) If Mars had a sufficiently large nearby moon, Mars would be able to support life.
-->this may be true hold for now
(B) If Earth’s Moon were to leave Earth’s orbit, Earth’s climate would be unable to support life.
-->sounds good .. hold
(C) Any planet with a stable, moderate axis tilt can support life.
-->pretty extreme statement, eliminate .. what if the planet is so far away from the sun life cannot live? not true all the time
(D) Gravitational influences other than moons have little or no effect on the magnitude of the tilt angle of either Earth’s or Mars’s axis.
-->extreme statement and seems a bit out of scope
(E) No planet that has more than one moon can support life.
-->extreme statement..this cannot be proven


Between A and B for me. Went with B because I had more information about Earth and felt more confident with it.

I picked D after narrowing down to B & D. I agree that B should be the answer but I don't like it as the question didn't say anything about the earth's orbit. Doesn't sound like a good GMAT question.

b) It is rather the gravitational influence of the moon that helps keep the angle of roughly 23 degrees. Even though it's true that Earth's climate will be unable to support life when the moon leaves, there's also no guarantee that Earth's climate will continue to support life if the moon is still around. Other factors such as global warming can eventually lead the climate to harm life even when the moon is still around.

The option is just talking about life, in case moon leaves. Its not talking about what happens otherwise.

D) Correct. The argument says, "That angle can be kept fairly stable only by the gravitational influence of Earth’s large, nearby Moon."

Th option says "little or no effect on the magnitude ...." whereas argument says "That angle can be kept fairly stable ONLY by the gravitational influence ....", so "little effect" is out.

D is incorrect because nothing in the passage has been stated regarding Gravitiational influneces other than that from Moon. We can't make any assumptions regarding gravitiational influences from other sources.
B is the clear answer.

I'll vote for B.

(A) If Mars had a sufficiently large nearby moon, Mars would be able to support life. - Cannot be inferred. Life to be supported needs other conditions.
(B) If Earth’s Moon were to leave Earth’s orbit, Earth’s climate would be unable to support life. Correct
(C) Any planet with a stable, moderate axis tilt can support life. - extreme answer not supported
(D) Gravitational influences other than moons have little or no effect on the magnitude of the tilt angle of either Earth’s or Mars’s axis. - extreme answer not supported
(E) No planet that has more than one moon can support life. - extreme answer not supported
