A or E, I would probably guess A.

I think it needs to be one of these two because you need the comma before "genetic endowments are the same" to imply that this is the case with all twins. Without the comma it's saying twins who also happen to have the same genetic endowment, which I believe is inaccurate.

Beyond that, I'm not sure if "unlike" or "other than" is more appropriate.

edit: Actually I'm going with E. Unlike doesn't make sense because the next part is "all people" and it's weird to say twins aren't a part of "all people". "Other than" does not bring up this potentially insulting issue!

A -- wrong. comparing transplants.. with all patients..
E - wrong.. comparing transplants .. with all patients.
Other than transplants between identical twins,.., all patients..
--> all patients, other than transplants between identical twins,... (wrong)
It should be like this.
all patients, other than identical twins... blah blah...

C is perfect.

wats wrong with B??

Besides changes the intended meaning of the sentence.

"Besides" is used when you must take two or more considerations together.

Besides doing regular exercise, you must also maintain balanced diet to keep healthy.
Means; "Doing regular exercise" should co-exist with the other condition i.e. "eating healthy diet". In other words, besides is kind of supportive word.

What we need is a contrast:

What the sentence is trying to convey:
If the transplants involve identical twins, antirejection drugs are NOT necessary. But, if the transplants involve other patients who are NOT identical twins, antirejection drugs are necessary. There is a contrast.

Besides transplants involving identical twins with the same genetic endowment, all patients receiving hearts or other organs must take antirejection drugs for the rest of their lives.

This statement appears as if "transplants involving identical twins with the same genetic endowment" is some sort of ACT or condition that all patients have to fulfill prior to getting the antirejection drugs.

1. Let’s appreciate that it is ' patients' that have to be compared with another set of patients or people
2. In this case A , B, D and E compare either transplants or transplant and therefore are wrong comparisons. C only compares in essence identical twins (meaning identical wins who receive transplants) with ‘all patients’. Hence, the right answer.
3. Lucky that four out of the five choices can be stroked down on the very first count .

C is the best for displaying contrast!

This is the OA:

In A and B, the phrases beginning Unlike and Besides modify patients, the subject of the main 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.

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.

The use of "who" in option C refers to "those identical twins who have the same genetic endowment", as if there were other twins who did not have the same genetic endowment. However, the logical and intended meaning is that "all identical twins have the same genetic endowment".

Therefore, even if option C is the correct answer, I believe that it still has an error in it.

Can any expert please comment on this observation?
