In November 1753, the British author Sarah Fielding accepted half the

Isn't Choice E supported by the fact that the author does take a stand implying the collaborative effort of Fielding and Collie by saying (especially the part in bold) "This particular collaboration was likely enough, as the two were close friends with common interests......Tey wrote jointly authored letters, were both published authors with a lively interest in each other’s work, and were enthusiastic supporters of didacticism and innovation in fiction central concerns of The Cry"?
Please help me understand.
Thanks.

UtkarshAnand This is quite tricky, but from the context, "likely enough" does not mean the same as "likely", and does not mean that the author fully agrees with the opinion of "many" in the prior sentence: "many think that the novel was a collaborative venture".

The language "likely enough" and the rest of that sentence admits that there is some reasonable logic for the "collaborative venture". However, the author does not go so far as to take a strong stand either way.

We then see the author make a contrasting point in the next sentence, signaled by the Contrast Marker word, "However": "However, contemporaries ascribed the work solely to Fielding,..."


Note that on the GMAT, there is a common "Myth" pattern similar to this question:
Many people believe X.
However, they are wrong because...

Or, another similar structure uses a concession/contrast word such as "while".
It's commonly believed that X.
While X may seem true from earlier data, new data shows that X is wrong.

After seeing this pattern many times, you may become particularly alert when you notice language such as "Many people believe...", and see if there is contrasting language that follows. Also, make sure to always distinguish clearly between the author's belief and any other groups' beliefs.

Q1 is wrong.

OA:

All three choices are correct. The question asks what is offered as evidence of the joint
authorship of The Cry.
Choice A is correct: the passage states that Fielding and Collier “were close friends.”
Choice B is correct: the passage states that Fielding and Collier “wrote jointly
authored letters.”
Choice C is correct: the passage states that Fielding and Collier were both “enthusiastic supporters of didacticism and innovation in fiction.

BUT

I understand how the passage reconciles Fielding with approach to fiction (Fielding was a enthusiastic supporter of something, and this topic was an important concern in The Cry. Ok.

The passage does state that both Fielding and Collier ("Their appraoch to fiction") were enthusiastic supporters of didacticism and innovation in fiction, but it doesn't explicitly state that this was Collier's personal approach to writing fiction. It indicates support rather than an approach. Maybe fielding 

Given this clarification, III might be considered a less definitive piece of evidence compared to I and II. Therefore, the best answer based on the passage should be: I and II.

There is no way to infer this kind of information, without stepping outside of the box. But this would be a violation against the basic rules of GRE (this passage is from the GRE Verbal Question Pack).­ The question also says: "The passage presents.." This means the answer must be stated in the passage. It doesn't say suggest, infer, would, should, could bla bla bla. It says PRESENT.

If you dont agree with me, please feel free to correct me. Thanks.­

I couldn't clearly understand why D is wrong.
The passage says that generally people thought they had shared interest in this part :-

Indeed, many think that the novel was a collaborative venture between Fielding
and Jane Collier. This particular collaboration was likely enough, as the two were close
friends with common interests.

and then author contrasts this using this part

However,
contemporaries ascribed the work solely to Fielding, and there is nothing in the novel
that is incompatible with Fielding’s other writings.

So can't it be said that the author would agree with the statement that their shared interest were not as wide as generally thought ?

Also what is the evidence that the author also believes that Fielding and Collier did not write Cry together? Author has only said that the contemporaries ascribed the work solely to Fielding.
