J.J. Thomson, the discoverer of the electron and a recipient of the Nobel Price in physics, trained many physicists, among them seven Nobel Price winners, 32 fellows of the Royal Society of London, and 83 professors of physics. This shows that the skills needed for creative research can be taught and learned.

Which one of the following is an assumption on which the argument depends?


(A) J.J. Thomson was an internationally known physicist and scientists came from all over the world to work with him

(B) All the scientists trained by were renowned for their creative scientific research

(C) At least one of the eminent scientists trained by J.J. Thomson was not a creative researcher before coming to study with him

(D) Creative research in physics requires research habits not necessary for creative research in other fields

(E) Scientists who go on to be the most successful researchers often receive their scientific education in classes taught by renowned research scientists

definitely C
The premises are that creative research can be taught and learned, and that JJ. Thomson was able to train people to become fellows (32), Nobel Prize winners (7) and professors of physics (83). Therefore, it follows at least one of those people was not a creative researcher before studying with JJ. Thomson.

B does not work because it does not attack the premise that creative research can be taught and learned.

OA is C

Permise : JJ trained some scientists
Conclusion : kills needed for creative research can be taught and learned
Unstated permise : At least one of scientists trained by J.J. Thomson was not a creative researcher before coming to study with him

Can some one help validate the negation of answer choice (C)?

(C) At least one of the eminent scientists trained by J.J. Thomson was not a creative researcher before coming to study with him

in short Choice (C) says that

Some of the trainees were not a creative researcher prior to JJ's training.

Some can be between 1 to 100, both included.

Negation -

None of the trainees was not a creative researcher prior to JJ's training.
(I am getting confused with this double negative - none and not)

Treat it like this ,
None of the was a creative researcher prior to JJ's training.
If this is true , this clearly breaks our conclusion- creative research skills can be taught.
Hence C is answer

Another Tip for my fellow friends:

in Assumption questions, whenever you see words like "At least one" or "At least some" in answer choices... they are the MOST likely answers.!

OA has been added. C is the correct answer because of the following reason:

Conclusion: The skills needed for creative research can be taught and learned.

If ALL the scientists trained by J J Thompson were already creative researchers, then it cannot be confirmed that because of the training, they became so. The assumption behind the above conclusion is that there has to be at least one scientist, who was not a creative researcher - the training made him so.

A) J.J. Thomson was an internationally known physicist and scientists came from all over the world to work with him
The choice provides additional information which is irrelevant and also out of scope since the nationality of the physist and scientists is not discussed.

(B) All the scientists trained by were renowned for their creative scientific research
The argument does not provide the exact number of students JJ Thomson had and there fore this choice does not make a good choice.

(C) At least one of the eminent scientists trained by J.J. Thomson was not a creative researcher before coming to study with him.

The answer choice is correct since it strengthes the link between the teaching of JJ Thomson and that all the scientist were not creative and renowned before learning for JJ Thomson.

(D) Creative research in physics requires research habits not necessary for creative research in other fields
Other fields is out of scope for this argument.

(E) Scientists who go on to be the most successful researchers often receive their scientific education in classes taught by renowned research scientists.
May not be true therefore this choice does not make a good answer.

choice C

lets do the negation of the choice c and conclusion falls apart-
(C) At least one of the eminent scientists trained by J.J. Thomson was not a creative researcher before coming to study with him

at least one ( means 1 to 100) or some on a scale of 0 to 100
negation of atleast one is - none or no one

so negation of choice c becomes
None of the eminent scientists trained by J.J. Thomson was not a creative researcher before coming to study with him- double negative, so in affirmative the same sentence is
some of the eminent scientists trained by J.J. Thomson were creative researchers before coming to study with him

now conclusion breaks down
choice E is close but if you look the words, it talks about the most successful researchers

the answer must be C
this is necessary info for the argument to holds true ,as there must be At least one of the eminent scientists,who had learned skills for creative work, trained by J.J. Thomson,

(E) Scientists who go on to be the most successful researchers often receive their scientific education in classes taught by renowned research scientists

The argument describes that the creativity can be taught and learned, for that to be true one must say that ebfore comming to learn from JJ Thompson students were not creative,
if they were creative already then it cannot be a fact that they learned it in the class of JJ Thompson,Option C provide the correct point as was done in prethinking.

sayantanc2k Please verify whether my pre-thinking is correct (or not). Thanks :)
(Especially the point 2, I am not very sure about that).

1. What if they were never taught creative research – meaning what if they were creative before being taught by J.J. Thomson. This breaks the conclusion.
2. What if all the professors he taught were not creative - Meaning What if not all professors he taught were creative. This too breaks the conclusion.

Official Explanation



If the physicists trained by J. J. Thomson were creative researchers before studying under him, then clearly the argument would be specious. On the other hand, if none of the physicists were creative researchers before studying under Thomson, then the argument would be strong. However, the argument does not require this strong of a statement in order to be valid. All it needs is one person whose research skills profited from the tutelage of Thomson. The answer is (C).

Many students have problems with this type of question. They read through the answer-choices and find no significant statements. They may pause at (C) but reject it—thinking that the argument would be deceptive if only one person out of 122 profited from the tutelage of Thomson. However, the missing premise doesn’t have to make the argument good, just valid.
