Why is (A) incorrect?

Is it because although Believed correctly modifies garbage, the modifier THAT here incorrectly modifies entire preceding clause
and we need parallelism as suggested better in (B) D and E are total mess since we need FANBOYS to connect two independent clauses.
C is out because of modifier issue. Coma + believed is incorrect.

A is incorrect due to a misplaced modifier. The closest noun to "believed to have originated from local hospitals" is scows. So A incorrectly implies that scows originated from local hospitals.

I think all the answer choices are incorrect .I found B is wrong because it uses "this" to modify an action or an entire clause.Is it acceptable?

Hey adkikani ,

'That' in A is actually used as an essential modifier, hence making a wrong meaning.

Moreover as abansal1805 mentioned, it has modifier issue as well.

Hey techiesam ,

I don't think there is any issue with option B. By using 'and this' , we are trying to convey the result of what happened in the previous clause.

But Manhattan GMAT says to avoid "this" kind of use of this.It says Finally, on the GMAT, do not use this or these in place of nouns. A sentence such as This is great is unacceptably vague to the GMAT. and this, like every pronoun, refers to some noun phrase, not to any clause.

According to Manhattan GMAT

Scientists have found high levels of iridium in certain geological formations around the world, AND THIS suggests the cataclysmic impact of a meteor millions of years ago.---The sentence is wrong.

techiesam I agree that the use of "this" in B is not very GMAT-like. However, there is no better answer. The sentence is clearly trying to convey that the whole situation may be responsible for the levels of pollution. It doesn't make sense to say that the refuse itself "provides an explanation," because we're trying to understand why that refuse/pollution is showing up on beaches, so we need to include the practice of dumping. B is not a very good answer, but the others are worse.

Can any expert suggest why THIS is correct? I thought that the THIS pronoun cannot be used to refer to an entire clause.

generis GMATNinja Is the usage of "This" to refer to the clause correct? Can a preposition refer to an entire clause? if yes, then which ones can refer to the entire clause.

Hi Arvind42 , up to now, GMAC has not accepted the use of this to refer to a clause or the idea or event described by that clause.

Some grammar constructions have no gray areas.
Subjects and verbs must agree.
Fragments or comma splices are incorrect.

We cannot predict with certainty what GMAC will do next in areas that occasionally become gray areas.

Will GMAC publish a question in 2021 in which "this" is allowed to refer to a clause?
Highly doubtful. But I cannot give you a guarantee.

I am 99 percent certain that GMAC will not allow THIS to stand for a clause.
For example, in one official question that has appeared year after year in the guide, the word this is used as it is in (B) here,
and the official explanation contains exactly one sentence about (D): The referent of THIS is unclear.

Spoiler alert: One incorrect answer to the official question just referenced is revealed.
In this official question (OG 2020 #879), HERE, the OE rejects (D) solely because "[the word] THIS has no clear referent." In that option D, this is supposed to refer to the facts described in the clause.


The rule seems clear enough.

Dmitry Farber, above, wrote a great answer.
This question is not very GMAT-like.
The other four options contain errors that are worse than the "this" error.

Takeaway: I am 99 percent that GMAC would not allow "this" to stand for an entire clause or an unstated idea.
In this question, we choose option (B) despite what is almost certain error in its use of "this" because (B) is the best of the lot.

I hope that analysis helps.
