On the basis of the Big Bang theory scientists predicted levels of Helium-3 in the universe that are ten times greater than the levels actually observed. According to the original model, Helium-3 is produced when low-mass stars burn up hydrogen and become red giants, as well as being produced in the Big Bang itself. Researchers have now produced a new model in which the Helium-3 produced by a red giant is pushed to the stars interior and burnt up. Hence the Big Bang theory is no longer undermined by Helium-3 data.

The two portions in bold-face are related to each other in which of the following ways?

A. The first highlights an observation that tends to undermine a particular theory. The second is that theory.
B. The first is a fact that undermines a theory. The second is context for accepting that theory.
C. The first points to an inconsistency in a particular model; the second is the authors main conclusion.
D. The first is a challenge to a classic theory; the second resolves that challenge.
E. The first is a position that the author does not accept; the second is the authors position.

Only options C and E correctly capture the role of the 2nd BF.
However, I don't understand why C is correct.

If the Big Bang theory is not actually undermined, what is the inconsistency in the model?

Official Explanation

Study each sentence carefully and decide whether it is a fact, and assumption or a conclusion. The first part in bold is a factual statement of a certain prediction. The second part in bold is a statement of the authors view or position on the situation. A view or a position is another way of thinking about a conclusion. So, start with looking for answers that say the second is a conclusion. Now we can have a closer look at C and E. Since the first part is a factual statement, we cannot say that the author does not accept it, and we are left with C. The word inconsistency is fine as the predicted amounts do not match with the observations.

Correct Answer: C


Hope it helps

The first BF indicates that Helium predicted (as per Big bang theory) is much higher than the actual Helium found. So the Big bang theory suggests something that is not true. Thus BF1 points out an inconsistency in the Big bang theory.

Later in the passage an alternative model is stated to explain this discrepancy, but BF 1 does not refer to this alternative model.

Why D is not correct? Would anybody explain the reason why D is not correct?
