Doctors, in seeking a cure for aphroditis melancholias, are guided by their research into the causes of metaeritocas polymanias because the symptoms of the two diseases occur in populations of similar ages, manifesting symptoms in both cases of high fever, swollen glands, and lack of appetite. Moreover, the incubation period for both diseases is virtually identical. So these medical researchers are convinced that the virus responsible for aphroditis melancholias is very similar to that responsible for metaeritocas polymanias.
The conclusion of the author rests on the presupposition that
(A) metaeritocas polymanias is a more serious public health hazard than aphroditis melancholias
(B) for every disease, modern medical science will eventually find a cure
(C) saving human life is the single most important goal of modern technology
(D) aphroditis melancholias is a disease that occurs only in human beings
(E) diseases with similar symptoms will have similar causes

Dear SajjadAhmad,
I'm happy to respond.
Pure trash. That's my opinion of this question.
As I have pointed out in other places, it's relatively easy to write high quality quant practice questions: most the quant questions on this site, including those from a variety of companies, are reasonably good. By contrast, it's very hard to write good verbal questions, and I would estimate that of the non-official questions on this site, perhaps as much as 50% are of extremely poor quality. This question is a prime example.
When someone is writing a question about a topic, of course it has to be written in such a way that the test taker doesn't need specialized knowledge of that topic--but it's often overlooked that the question writer does need specialized knowledge of the topic! The medical procedures suggested in this prompt are utterly absurd! These doctors following this procedure would not garner a dime of research money with this argument! These would be doctors that would not pass a high school biology class! Embarrassing! You see, all CR arguments on the GMAT have the "feel" of the real world: they capture the real motivations of real people in real situations, even if the names are fictional. It's fine that the two diseases are made up--in fact, that's the only part of the question that I like! The scenario was extremely poorly chosen: the confusion of similar result and similar cause might work in another context, but in the highly rigorous field of medical research, this is patently absurd.
The word "presupposition" is a very odd word in the prompt question. I don't think I have ever seen the GMAT use that word rather than "assumption" for an assumption. That's just a matter of being familiar with the language used on the test.
One of the very difficult parts writing a challenging GMAT CR practice question is writing four incorrect answer choices that are unambiguously wrong but tempting in some way for students who don't read carefully or have a predictable confusion. In this question, the four distractors (A)-(D) are a joke! They are not the least big plausible. It's very easy to make an incorrect CR choice that is clearly 100% over-the-top wrong--all four of these are--but the hard part is to write four choices that are 100% wrong and yet at least some of them will be plausible to certain students. Almost 100% of GMAT-ready student would get this question right: it is would be the lowest possible percentile.
This question fails on every possible aspect of evaluation. It is an utter embarrassment. I would give it a grade of an F.
Here's a high quality GMAT CR practice question:
Simian Virus
Does all this make sense?

Oh Man! This CR very well fits with situation of Pneumonia and Covid-19 symptoms
Both diseases has almost similar symptoms.
