If you have the comma and fanboys combination, the phrase after it must have both a subject and a verb.

@ catseye and @atulmangal :

This is an example from 1000 SC , which shows how ",and" can also be used while describing items of a list.

137. As Russell Banks suggests, it is a lack of grand ideas that have only left writers with semiotics, hermeneutics, and deconstruction.
(A) As Russell Banks suggests, it is a lack of grand ideas that have only left writers with
(B) Writers, Russell Banks suggests, who lack of grand ideas and leave only
(C) Russell Banks suggests that a lack of grand ideas has left writers with only
(D) It is Russell Banks' suggestion that a lack of grand ideas have left writers only with
(E) It is only a lack of grand ideas, Russell Banks suggests, which leave writers with

OA is C

Tega1984 wrote:Can anyone help me out with this one?

The people of the ancient Assyrian Empire were renowned warriors, although they also crafted some of the best-preserved ancient art.

A) were renowned warriors, although they also crafted
B) had been renowned warriors, although they also crafted
C) were renowned warriors, and also crafted
D) was renowned warriors, although they also crafted
E) were renowned warriors, but also crafting

The correct answer is A but what is wrong with C? They say that there's a comma splice mistake in C, but how is it a comma splice when there is a coordinating conjunction AND after the comma?

If one subject has two verbs, we need not use COMMA before the second verb.

Example:

I have worked hard and won the prize.--correct.
I have worked hard, and won the prize.---Incorrect.

Come to the sentence:
The people were renowned warriors, and crafted. ---incorrect.

The subject, people, has two verbs--were and crafted.We should not use COMMA before the second verb.

Again, we are not required to use COMMA + AND in case of a list of two things.

Example:

I need X and Y.--correct.
I need X, and Y. --incorrect.

Thanks.

@Gmatmadeeasy

when second independent clause shares the same subject as first one and the subject is not repeated, you don't use comma in second IC. (only true when connector is AND)

from where u get this rule (in blue one)...??? Is it based on your experience or it is from some standard resource.

In laboratory rats, a low dose of Aspirin suffices to block thromboxane, a substance that promotes blood clotting, but does not seriously interfere with the production of Prostacyclin, which prevents prevents clotting.

The above sentence is the correct answer of a gmat prep question...u can see this question here on this link

https://www.beatthegmat.com/gmat-prep-sc ... tml#361251

If i apply your rule (the one in "blue" color i marked) then i can understand why the above example is correct but if i apply the generalize thing as @Tani and others suggested

@Tani

I didn't find this rule applicable here in my example

In laboratory rats, a low dose of Aspirin suffices to block thromboxane, a substance that promotes blood clotting, but does not seriously interfere with the production of Prostacyclin, which prevents clotting.

In this example the comma before "but" is not being used to join two independent clauses, but is simply setting off the phrase "a substance that promotes blood clotting". If you remove that modifier, you have

In laboratory rats, a low dose of Aspirin suffices to block thromboxane but does not seriously interfere with the production of Prostacyclin, which prevents clotting.

IN this form you do not need the comma before "but".

A. The subject is "lack", not "ideas" (the subject is not inside a prepositional phrase. Therefore, you need "has" instead of "have".

B. This is awkward and "who lack ofgrand ideas" is incorrect. The "of" is not needed.

D. Again, you need "has" instead of "have". Also, the "it is" construction is wordy and awkward.

E. Again the singular subject calls for a singular verb ("leaves", not "leave").

Thanks a lot @Tani...this clear my doubt...

so in this question, we can say that Op C is wrong because of incorrect use of COMMA + FANBOY right??

The people of the ancient Assyrian Empire were renowned warriors, although they also crafted some of the best-preserved ancient art.

A)were renowned warriors, although they also crafted
B)had been renowned warriors, although they also crafted
C)were renowned warriors, and also crafted
D)was renowned warriors, although they also crafted
E)were renowned warriors, but also crafting

Exactly!

Hi,

I have gone thru the COMMA + FANBOYS information and I follow it here - https://www.textbroker.com/blog/content/ ... boys-.html - also. However, I do have a sentence of Economist ( https://www.economist.com/node/21534821 Last sentence of the article ) that is

Mr Rajoy will come under pressure to respond. All this will take years but, happily for the long-suffering Basques, there is no taste for turning back.

I believe if the modifier " happily for the long-suffering Basques," were not present in the sentence then there would not be a COMMA after "BUT". However, the sentence " there is no taste for turning back" is a complete sentence. So there should be a comma before "BUT"?

Would you please throw some light on this part? Is the sentence of Economist is correct? If yes, please explain.

As Russell Banks suggests, it is a lack of grand ideas that have only left writers with semiotics, hermeneutics, and deconstruction.

(A) As Russell Banks suggests, it is a lack of grand ideas that have only left writers with
(B) Writers, Russell Banks suggests, who lack of grand ideas and leave only
(C) Russell Banks suggests that a lack of grand ideas has left writers with only
(D) It is Russell Banks' suggestion that a lack of grand ideas have left writers only with
(E) It is only a lack of grand ideas, Russell Banks suggests, which leave writers with

In the above question, I understand that in (D), " it is" is ambiguous.
But for option (A), what does "it is" signify?
