The great thing about SC is that there are numerous errors in sentences.I can point the pronoun error in the original sentence "it" in the first sentence.

The pronoun "it" has only one logical antecedent is profits but the antecedent is plural.

As I see in the Og,the same issue is with B!

We are left with C,D,and E

D and E introduce modifier errors.

with is a preposition that means accompanied by something

eg Please walk with me.

The old man with spectacles

with also is used to refer to some instrument with which work is done.

He wrote with a pen on the paper.

Now to the sentence:

It is unclear what is accompanied with a 5% increase.It could be measures [the cost cutting measures] or the profits .

Answer Choice D and E introduce such issues.Besides,answer choice E introduce awkward [having].GMAT doesn't like words such as having or being,unless they are involved in ||ism [somehow if the word were eliminated,the sentence would be grammatically incorrect].

which in answer choice C is very specific [profits].Therefore,C is the answer

C which have increased 5 percent during the first 3 months of this year after falling

The correct answer is c.

The og said that the first indicator, a 5 percent increase in profits, occured after the indicator, falling, mentioned next. Therefore the sentence needs to clarify the sequence by presenting the first-identified indicator in a clause with a verb tense that indicates a later time period than the verbe sense in the clause presenting the second-identified indicator.

In choice C, How could I see that the first verb(have increased )happens later than the second verb(falling)? Could you please give a help? thank you very much.

This is one of the odd points of GMAT.But the fact is that the word after indicates that the action happened later,so you need to overemphasize that fact [as per MGMAT SC guide].They have used an eg very similar to this one.The more glaring issue here is pronoun error in A and B

Rishab1988, thanks so much for your detailed explanation. It is true that the glaring issue of the original sentence is the pronoun error. I am just confused by the og explanation about the verb form. And, the After+ falling is just so weird.

I totally agree.Sometimes OG has very weird explanations[case in point the idiom so...as to vs so as to],but the good thing about SC is that there are multiple errors.I have 70% accuracy at 700-800 levels questions [MGMAT],so I know a thing or two about SC.

I have seen that OG has justified the idiom "so X as to Y" at one place and the idiom "so as to" at another.Btw so as to basically means the same as to.If you find an answer choice that is grammatically correct andthat uses word to instead of so as to then choose that answer choice over the other.

I should remember what you say. Thank you so much for your prompt answer.
