C it is .

A is wrong as transplants are compared to patients.
B is wrong for the usage besides and transplants compared to patients.

D usage of aside.
E : same problem.

Got C, A was tempting for a bit, but C made more sense.

What is POE?

I am confused here. All the options seem to have been comparing transplant(s) with all patients. How come C is different than the rest of choices?

Joshnsit,
The SC is not just about comparison between transplants in group 1 vs transplants in group 2 but also the right usage of sub-ordinate conjunctions .

In this SC , "besides" and "Aside" dont make sense. The SC is about comparison and not about anything other than transplants. "Besides" and "Aside" indicate activity/operation other than transplants.

Hope this helps.

Instead of looking at it from the point of view of comparison, let's look at it from the angle modification. ABD and E are sentences starting with a participial phrase modifying the noun ‘all patients.’ Therefore you can not dispense with necessity of modification from these choices. C alone among the choices uses a subordinate clause with its own subject and verb, totally obviating the need for modification. A subordinate clause is not required to modify the main clause but only has to depend upon it for completion of the meaning. That is the reason C is different from the rest

Good Question. Check for Comparison between patients and any other living being which is stated only in Statement C.

Hi Experts,

egmat, mikemcgarry, sayantanc2k

I want to thoroughly understand the difference between the usage of with and who here:

(B) Besides transplants involving identical twins with the same genetic endowment
(C) Unless the transplant involves identical twins who have the same genetic endowment

Well i just noticed that this old posted question does not have official answer updated. I will update that.

But i will encourage you that always write some explanation rather than just posting the choice letter. Most of the time I would post an explanation for which either i would get kudos, get some remark on my explanation or will receive some comment from an expert telling me that where i was wrong in explanation. Posting with some content helps in multiple ways.

Hope you get the point

Hi Experts,

egmat, mikemcgarry, sayantanc2k

I want to thoroughly understand the difference between the usage of with and who here:

(B) Besides transplants involving identical twins with the same genetic endowment
(C) Unless the transplant involves identical twins who have the same genetic endowment

Elaborating on my confusion and some analysis i did:

Here is the official explanation:
You answered "Unless the transplant involves identical twins who have the same genetic endowment" and that's correct because:
In A and B, the phrases beginning Unlike… and Besides… modify patients, the subject of the main clause; thus A absurdly states that Unlike transplants…, patients…must take…drugs, and B that all patients except for transplants…must take… drugs. In B and D the expression identical twins with the same genetic endowment wrongly suggests that only some identical twin pairs are genetically identical. In E, the construction Other than transplants…, all patients… must take… drugs illogically suggests, as in B, that some patients are transplants. Choice C, the best answer, solves these problems by using a clause introduces by Unless to describe the exception to the rule and a nonrestrictive clause beginning with who to describe the characteristic attributed to all identical twins.

Confusion and Analysis:
As it looks like both of the following have the same meaning, I got confused by the explanation (highlighted), especially for choice correct choice C in which who is termed as nonrestrictive).
(B) Besides transplants involving identical twins with the same genetic endowment
(C) Unless the transplant involves identical twins who have the same genetic endowment

I found one of RON's posts in which he mentions that for "a nonrestrictive clause beginning with who to describe the characteristic attributed to all identical twins." to be true there has to be a comma before "who" in choice . here is the link: https://www.manhattanprep.com/gmat/forums/restrictive-vs-non-restrictive-t25787.html#p96242
Yes that's the concept we have learned about norestrictive or nonessential modifiers.

BUT when i looked up meaning of "who" that says - "used to introduce a clause giving further information about a person or people previously mentioned."
Now this seems to confirm that no comma is required and given official explanation is correct.

I need Experts' opinion on my understanding.

Thanks

Your understdning is absolutely correct: "with" and "who have" (without comma) convey the same meaning (a subgroup of twins).
