Graduates of medical schools are interested in practical

I have to question the OA on this one. As mentioned earlier, when you have difficulty finding the true assumption you can negate the possible assumptions and choose the one that destroys the conclusion.

Conclusion: research laboratories rarely hire graduates of medical schools
Negated D: Research laboratories would NOT hire graduates of medical schools if such graduates were interested in research work.
Negated E: Most medical school graduates who are interested in practical work are also interested in research.

If we insert Negated D into the argument, the conclusion isn't destroyed but rather supported.
If we insert Negated E into the argument, the conclusion is destroyed because there is now no valid reason to not hire a medical school graduate.

This provides strong evidence for E as the OA...

IMO, D is correct.

Premise: medical students are interested in practical works.
Premise: research laboratories are reluctant to hire personnel who are not interested in research
Conclusion: research laboratories rarely hire graduates of medical schools.

This is supporter assumption.
IMO, the assumption is: research labs rarely hire medical students because these graduates are not interested in researches. (If graduates of medical schools are interested in researches, research laboratories would hire them.)

D says: Research laboratories would hire graduates of medical schools if such graduates were interested in research work.
To confirm, we will negate this assumption. Research laboratories would NOT hire graduates of medical schools if such graduates were interested in research work. ==> there's NO correlation between research labs hiring and graduates of medical schools. ==> The conclusion fails.

can some one help me in negating option C?

Hi skamal7,

Look at the conclusion which says :
Consequently, research laboratories rarely hire graduates of medical schools.

So the option C follows from this conclusion and is not required to support the conclusion.

Thanks

optionc :
C)Most employees of research laboratories are not graduates of medical schools.
Here if i negate
a) some employees of research laboratories are not graduates of medical schools.
b)Most employees of research laboratories are graduates of medical schools.

Among the two options which is the correct one to negate the option c?can you please help..

I think you are getting confused here.
The option C is not an assumption but an inference which can be drawn from the author’s conclusion that research laboratories rarely hire graduates of medical schools.
So it can’t be the answer as the answer has to be an assumption which helps the conclusion.
Now the conclusion is drawn from the fact that Graduates of medical schools are interested in practical work as practicing physicians and hence not interested in theoretical work. And so research laboratories which do theoretical work will not hire them. The underlying assumption here is that if graduates are interested in practical work then research labs will hire them and this is what option D days.

I to feel that option D, when negated, supports the argument instead of weakening the argument.

KW explanation is correct . I put the wrong answer . OA is indeed "E" ( not "D" as marked earlier)

Here's the OE if anyone is interested :



The argument above concludes that research laboratories rarely hire medical school graduates. As evidence, the argument states that most graduates of medical schools are interested in practical work and that research laboratories are not interested in hiring personnel who are not interested in research. This argument is correct only if it assumes that medical school graduates interested in practical work are not also interested in research. If they were also interested in research, research laboratories should be interested in hiring them, because, as implied in the argument, research labs are interested in hiring personnel who are interested in research.

A) The argument does not depend on the assumption that graduates of medical schools are interested in working in research centers.

B) This does not need to be assumed. The argument is quite compatible with the idea that there are people who are not interested in research work and are not interested in practical work.

C) This choice paraphrases the argument; it does not need to be assumed.

D) The argument states that being interested in research work is an important criterion for being hired by a research laboratory, but nothing in the argument indicates that this alone is sufficient to be hired. Laboratories should be interested in hiring those graduates but not necessarily bound to hire them.

E) Correct. If many of those graduates were interested in research work as well as in practical work, then laboratories would be willing to hire them and more graduates would work for research labs. Therefore, it must be assumed that medical school graduates who are interested in practical work are rarely interested in research work.

It is a clear E for me...for conclusion to be true, graduates must not show interest in research. E states exactly this.

question about the negation test here:

I have a little problem with the negation test over here
the OA says:

(E)Few medical school graduates who are interested in practical work are also interested in research.

but, when I negate it I get:
NOT Few medical school graduates who are interested in practical work are also interested in research.

and as far as I know - "not few" can mean -
1. None
2. Most

it is obvious that the answer would be right if the word FEW also contains the word NONE inside.

what do you think experts?

Initially I also thought the option would be D; but after going through the explanations given by wiser people, I realise that this was not a 700 level for nothing.
For me the answer lies in the word "rarely" - the conclusion seem to indicate that at some point the medical student were hired - which could only be based on the assumption that some of the medics were also interested in the research.
Otherwise the conclusion should have been - medical students are never hired.

Can someone please help me understand how option B is not correct here ?

When negated it becomes, 'The only people interested in research work are those who are NOT interested in practical work' which weakens the argument.

The only objection I have with E is the word "few".
