Good catch. or a poor miss on my part :oops: .

I have been making this mistake of missing redundancies. How do I avoid them? I read this so many times before posting it but alas it slipped everytime.

Can you suggest a way to avoid such stupid error?

Going back to my original point - Option D seems to have an incomplete sentence after 'but'.

The best way is to do a Lot of Practice ... I think there is no shortcut to success.
Coming to your second ques:
In a run on sentence, both the sentences before or after the comma are complete. You are stating otherwise.

Another reason i choose D is the parallel construction after "but"

if the purchase price is refunded back to the customer's credit card
should be parallel to "if given as store credit"

In ans D

if the purchase price is refunded to the customer's credit card
is parallel to
"if the refund is given as"

Many online retailers charge “restocking fees” on returns if the purchase price is refunded back to the customer's credit card, but charge no such fees if given as store credit.


a. if the purchase price is refunded back to the customer's credit card, but charge no such fees if given as

b. for purchases that are refunded to the customer's credit card, but not when those purchases are refunded as

c. when the purchase is refunded back to the customer's credit card, but not given in the form of

d. if the purchase price is refunded to the customer's credit card, but not if the refund is given as

e. whose purchase prices are refunded to the customer's credit card, and charge no such fees if refunded

I got stuck between a and d. The option 'd' does not seem to have complete sentence after but. So we have a run on sentence. Am I missing something?

"refund back to" in choice A and C is redundant. So, they are out. Choice D is truly complete because the 2nd part is only opposite with the 1st part, it's used to collaborate the 1st. "The purchase price is refunded" can be alternated by "the refund" \. Choice C shows "in the form of" is no clear meaning.

Choice E is wrong because of the meaning of the 2nd part "charge no such fees if refunded".

i've got stuck between A and D too. but finally choose D. in my point of view, the meaning is a bit ambiguous. what is given the price or the fees. in D the intended meaning is clear.

Man, this is a good problem.

Here's mine:

First, read the entire sentence. Then read each answer choice (beginning with A). After reading each, there are three easy eliminations: A, C, and E. A from "if given" and "refunded back", C from "but not given", and E from "whose".

For B & D, we basically need to decide between "for purchases" and "if the purchase price". It looks like D is the way to go, plus it's more economic, which helps.

D...

OA! :)

Try this:

When you compare two sentences, what is the difference between the two?

If you spot the difference to an additional word in one versus the other, check if this word is "needed". This is your test for redundancy.

In the give question, between A and D you can spot "refunded back" as the difference, it is present in A absent in D. Immediately pop the question "is the word "back" needed or is it redundant?" you might find it easier to spot those then.

D for me too. the purchase vs purchase price eliminated 2 immediately. though i didnt catch the redundant "refunded back" (good one rohitgoel!), D felt the best answer for the use of but and IIelism

This question just popped up in a CAT that I took last week. While taking the test (and I was rushed at this point), I saw the "if" and thought if-then statement and immediately crossed off a&d.

Now looking back I realize that if can be used in two scenarios (i) if-then, and (ii) hypothetical. Any advice on how can I get better at determining this distinction?

My thoughts are as follows - if answer choices switch between "if" and "whether", then go down the logic I followed in the test looking for "then". If not not an if-then scenario, go with "whether" to choose between two option. If a hypothetical situation then the correct answer should have an "if" in it.

Thanks in advance for any replies!

I Chose "D" based on parallel structure and the idiom If X But (not)Y. is this approach correct? I just learnt this way of application from MGMAT SC Guide. Not sure if what I assimilated is right an expert reply can help!

Since you have written "If X But (not) Y", there is an issue. The word "if" is within the the element X, not outside. The idiom is "X, but (not) Y":

X = if the purchase price is refunded to the customer's credit card
Y = if the refund is given as....
X and Y have the same structure.

However the structure you have mentioned depicts that "if" is not within the element X:
X = the purchase price is refunded to the customer's credit card
Y = if the refund is given as....
These are not parallel.

Could someone explain why B is wrong? I am struggling with this one because it seems to be a really subtle mistake (Refund of the purchase instead of the purchase price). Is there a grammatical mistake or is it only the meaning?

There is a parallelism issue in B. Since "but not" is followed by a "when" clause, there must be an opening "when" clause for the structure:

...for purchases that are refunded to the customer's credit card, but not when those purchases are refunded as.... wrong - faulty parallelism

...when purchases are refunded to the customer's credit card, but not when those purchasesare refunded as.... correct.

Refunded back is redundant. D is perfectly right. B is wrong because purchase cannot be refunded!

a. if the purchase price is refunded back to the customer's credit card, but charge no such fees if given as ---- refunded back

b. for purchases that are refunded to the customer's credit card, but not when those purchases are refunded as---- so purchase price is refunded not the purchase.

c. when the purchase is refunded back to the customer's credit card, but not given in the form of ---- refunded back

d. if the purchase price is refunded to the customer's credit card, but not if the refund is given as --- yes

e. whose purchase prices are refunded to the customer's credit card, and charge no such fees if refunded --- use of and, for meaning change we need to use but.
