D

As X, so Y - is a parallel structure. We compare traditional pharmacies with online drug stores.

I do not see any parallelism in C. we cannot compare case of traditional pharmacies with prescriptions.

What is OA?

C is OA,
As X, so Y --- X,Y are clauses here but in case at hand X is noun

I hope it clears the doubt

I've gone through many study materials for "As" Vs "Like" and was comfortable with this topic till I saw this post.

As is the case with traditional pharmacies, prescriptions are the cornerstone of a successful on line drugstore, since it is primarily prescriptions that attract the customers, who then also buy other health-related items.

This is given as correct answer and I've no questions around it. But one of the incorrect answers is given is "As with the case of traditional pharmacies, on-line drugstores rely on prescriptions to have success" . I know this choice is incorrect but my question is can a prepositional phrase follow "AS" when "AS" is used for comparison? My understanding is that as long as "AS" is used for comparison it has to be followed by a clause only, if a Prepositional Phrase example "with the case of pharmacies" it has to be incorrect. But nobody mentioned this in the reasons why this choice is incorrect and so I'm little confused.

How about the use of "Since ...Have" clause in Option C. I see only B has this. Can someone please clarify?

"Since" has two main usage:

1) It could mean "from then till now": Since 1990, the prices have increased.
In this case the meaning of the sentence is : the action "prices have increased" started in the past and its effects/consequences are still visible in the present.
In this case Present Perfect is the correct tense to express the meaning.

2)It could stand for "because": Since you're already here, you might as well stay.
In this sentence "since" is used as conjunction, not as an adverb (as above). The above concept does not apply here.

Hope it's clear

Thank You. Kudos to you for clarifying my confusion.

Hi All,

As it is with traditional pharmacies, online drugstores rely on prescriptions to be successful, since it is primarily prescriptions that attract the customers, who then buy other health-related items.

On reading the sentence carefully, we know that this sentence presents a comparison. The intended comparison is between traditional pharmacies and online drugstores. The point of comparison is that just like traditional pharmacies, online drugstores also depend upon the success of prescriptions for the said reason.
Since there is a comparison in this sentence, we can use either “LIKE + Noun” or “AS + Clause”. Let’s run the POE.

POE

A) As it is with traditional pharmacies, online drugstores rely on prescriptions to be successful: Incorrect. Pronoun “it” is referring to the entire clause “online drugstores rely on prescriptions to be successful”. This is incorrect because a pronoun can only refer to a noun or a pronoun.

B) As with the case of traditional pharmacies, online drugstores rely on prescriptions to have success: Incorrect. Since “as” has been used for comparison in this choice, it must be followed by a clause. But “with the case of traditional pharmacies” is a prepositional phrase and not a clause.

C) As is the case with traditional pharmacies, prescriptions are the cornerstone of a successful online drugstore: Correct. “As” is followed by a clause. Also, this choice maintains the parallelism by using “is” and “are”. What is the case with traditional pharmacies? It is that prescriptions are the cornerstone for their success. Hence, the comparison is parallel here.

D) As traditional pharmacies, so online drugstores rely on prescriptions to be successful: Incorrect. “As” is not followed by a clause.

E) Like traditional pharmacies, the cornerstone of a successful online drugstore is prescriptions: Incorrect. This choice presents illogical comparison. Here “traditional pharmacies” have been compared to “the cornerstone”. Also, use of “so” is not correct.

1. In comparisons, “like” must be followed by a NOUN.
2. In comparisons, “as” must be followed by a CLAUSE.
3. Pronouns can only refer to nouns and other pronouns.
4. Comparison should always be logical.

Hope this helps. Thanks.

Really great explanation!! wish I could give bonus kudos for this wonderful post

Wrong comparison in option A,B,D,E.
"Like" is used to compare noun/noun phrase and "As" is used to compare clauses

hi
sorry to say..but wanted to correct you.

LIKE is used to compare NOUN/NOUN PHRASE....but not CLAUSE OR PREPOSITIONAL PHRASES.

in option C we have a clause and not NOUN phrase.
As is the case with traditional pharmacies, prescriptions are the cornerstone of a successful online drugstore

THE CASE: SUBJECT
IS: VERB

hope it helps

The low success rate of the question made me shift towards D for a bit. I got C straightaway.

Just to add..I was expecting the online pharmacies after the comma....coz the initial modifier must modify the stuff intended..

But after some research I found this good discussion here
https://www.manhattanprep.com/gmat/foru ... 20-15.html

Like requires a correct comparison between two nouns. No exceptions.- So had online pharmacies followed the comma-it would have been a correct choice too

As also requires a correct comparison, but with the entire clause, not just the nouns: - So in C we are good as far as the modifying the stuff intended rule is concerned--Also C maintains parallelism--

Option C: As is the case with traditional pharmacies, prescriptions are the cornerstone of a successful on-line drugstore.

I think the word 'cornerstone' is actually adding to the meaning of the original sentence. Original sentence states that drugstore "relies" on prescriptions to be successful. This by no means implies that prescriptions are the "cornerstone" of success.

Comparitively, Option A seems better. As it is with traditional pharmacies, on-line drugstores rely on prescriptions to be successful.
Here "it" does not have an antecedent because it is not supposed to have one. Here "it" refers to the property of "it" where it does not refer to any noun etc.
While the pronoun “it” is most often thought of as a pronoun taking the place of a thing, we also use “it” as a placeholder that helps us manipulate the subject and object of a sentence. In these cases, “it” does not have an antecedent.
Delayed Infinitive Subject with “it:” It is good for the body to run often.
