Some scientists, who today are recognized for their brilliance, were once vilified for their work and considered insane during their lifetimes. It therefore follows that what is considered insane or not insane has changed over time.

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

(A) Works of science that are that are considered insane change the way in which the general public defines 'insanity.'

(B) The number of things that are considered insane has decreased with the passage of time.

(C) Public opinion does not determine the validity of scientific research.

(D) Not all scientists who were once considered insane are still considered insane today.

(E) Some scientists who are considered insane today were also considered insane in the past.

Responding to a pm:

It is an assumption question. It means you are looking for a gap between premises and conclusion. The premises are not enough to take you to the conclusion. You NEED the answer option to reach the conclusion. So the first thing we need to do is chalk out our premises and conclusion.

Premises:
Some scientists are recognized for their brilliance today.
They were once vilified for their work and considered insane during their lifetimes.

Conclusion:
What is considered insane or not insane has changed over time.

Now here is the catch. the premises say that some scientists were considered insane during their lifetime. They are being recognised as brilliant now. The premises do not say that they are not considered insane now - only that they are considered brilliant now. Note that we cannot assume that brilliance and insanity are mutually exclusive traits. Brilliant people can be considered insane too aka "mad scientists" .

To say that what is considered insane has changed over time, we are assuming that some of those scientists who were thought to be insane are not considered insane anymore.

Option (D) tells you this: Not all scientists who were once considered insane are still considered insane today.
So this is the correct answer.

All other options are just confusing or plain irrelevant.

IMO D

Conclusion: It therefore follows that what is considered insane or not insane has changed over time.
I assume that this is an assumption question as you tagged it as 'Assumption' .
Here is my reasoning behind picking D as answer.

Works of science that are that are considered insane change the way in which the general public defines 'insanity.' --Incorrect. Too broad and we are never concerned about what general public defines 'insanity' and it doesn't affect our conclusion. Out of scope.
The number of things that are considered insane has decreased with the passage of time.---Incorrect. Irrelevant whether number of things considered insane are decreasing over time.
Public opinion does not determine the validity of scientific research.- - Incorrect. Out of Scope and also doesn't affect our conclusion in any way.
Not all scientists who were once considered insane are still considered insane today.-- Correct. Negate this i.e. All scientists who were once considered insane are still considered insane today This implies that there is no change over what we consider insane today and in the past, falling apart our conclusion.
Some scientists who are considered insane today were also considered insane in the past.-- Incorrect. This was tempting for me. If I negate this i.e. None of the scientists who are considered insane today were also considered insane in the past. This doesn't really fall apart our conclusion if we read our conclusion carefully i.e. It therefore follows that what is considered insane or not insane has changed over time.. So I rejected this and went ahead with D

D it is : Not all scientists who were once considered insane are still considered insane today.

negate D : all scientists who were once considered insane are still considered insane today.----->this breaks the conclusion, which states "what is considered insane or not insane has changed over time"

negate E: NONE of the scientists who are considered insane today were also considered insane in the past---->this supports the conclusion !!

Maam with all due respect,don't you think D would have been right if it were a "must be true question".Because option D is just a paraphrase of the first line.But if we negate option A then we find out that if a scientific work is tagged insane and can't be changed then the hole argument falls apart.

My explanation given above clarifies why (D) is not the same as the first line of the argument. "Brilliant" and "insane" are not mutually exclusive. Hence, you need (D) to establish that what is considered sane has changed over time.

(A) Works of science that are that are considered insane change the way in which the general public defines 'insanity.'
Negated (A) Works of science that are considered insane do not change the way in which the general public defines 'insanity.'
This says that "works" have no effect on the definition of insanity.

But our conclusion is "what is considered insane or not insane has changed over time."
Even if the works have no effect on the definition of insanity, something else could have changed it. So this doesn't break down the conclusion.
