Hi
EducationAisle, I guess i am not well versed with terminonology, sorry about that, but while using FANBOYS, isn't it mandatory to use a comma before the conjunction if that conjunction is used to connect two IC as is the case here?
Hi Rohit, in this case, comma will
not be justified. Presence/absence of a comma depends on the
intended meaning.
Let's take the following two sentences:
(1) By asking questions, Rohit wants to clear this doubts, and he also wishes to reinforce his understanding.
(2) By asking questions, Rohit wants to clear this doubts and he also wishes to reinforce his understanding.
The only difference between these sentences is that there is no comma before
and in the second sentence. Let's see what impact this has, on the meaning.
Statement (1) depicts the following:
(1a) By asking questions, Rohit wants to clear this doubts, and
(1b) he also wishes to reinforce his understanding
Statement (2) depicts the following:
By asking questions,
(2a) Rohit wants to clear this doubts and
(2b) he also wishes to reinforce his understanding.
It should be very clear that (1) makes no sense, because "he also wishes to reinforce his understanding" is not a completely independent/unrelated fact, but is actually a consequence of "by asking questions". Hence, sentence (2) is more logical.
I have seen this meaning subtlety getting tested very occasionally on GMAT. Can perhaps dig out an official question.
