Explanation

A) This one is a bit tricky because a quick reading could lead you to B and C as answers but the OA is A and B. C is not the right one because is true, it will add only another hypothesis to the already crowded literature without creating a clear look inside the dispute.

B) Hre the word sensational actually means "a fanfare" but without a real fundamental or consistency truth.

i thought answer of second question would be "excellent" because opposite of "but weakly founded" must be something apparently "excellent".
so why its answer is dramatic here?

here the answers have two tones: one positive and one negative. You should be able to understand which side is correct and then pick the right answer.

Now, Consequently, both the public and the scientific community have often been misled by widespread dissemination of sensational but weakly founded hypotheses.

Focus on the bold part of the sentence. As such, excellent and eminent (which are positive) are wrong. horrifying is out of scope from the context of the sentence AND the passage.

False, we do not know because we are talking about hypothesis, which could be true or not. So we do not know for sure if they are false.

A is the best fit

Question 1:
Can you explain why it's not A?
The conclusion concerns about weak hypothesis widespread by amateurs, but even a renown biologist could not have proved if the data was incorrect or not, without a close examination . Option A didn't mention anything about further examination of the hypothesis at hand.

❑ An article written by a biologist for the general public summarizing current theories about avian and dinosaurian evolution

❑ A close examination of available data on avian and dinosaurian evolution

❑ A new hypothesis regarding the connection between avian and dinosaurian evolution

Actually, the theory and data that we already have are reliable and proven (someone could agree or not on this. However, here is not a point of discussion for now)

C says new hypothesis, which we do not know yet whether are true or not.

For these reasons A and B are correct and C is wrong.
