Prolonged exposure to exceptionally violent or chaotic circumstances can cause Post-Traumatic Stress Disorder (PTSD) in some individuals. Psychiatrists in Virginia indicate that the proportion of patients coming to them for treatment of symptoms related to PTSD has increased enormously over the previous five years. Thus, either Virginia has become a much more violent and chaotic place over the last fiver years or individuals are more sensitive to violence and chaos than they were five years ago.

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

A. The number of psychiatric practices in Virginia has not increased over the previous five years.

B. Individuals with PTSD are no more likely than other individuals to have other psychiatric disorders.

C. Individuals with PTSD are no more likely to seek diagnosis than they were five years ago.

D. Virginia is an exceptionally nonviolent and organised environment.

E. Individuals in Virginia do not live in violent and chaotic circumstances any more often now than they did five years ago.

C is the correct answer,

Negating C becomes - "Individuals with PTSD are more likely to seek diagnosis than they were five years ago" - If this is the situation then surely it shatters the argument by stating another reason of increase in treatment of symptoms related to PTSD .

C. Individuals with PTSD are no more likely to seek diagnosis than they were five years ago.
is the correct answer since using negation test,
if Individuals with PTSD are more likely to seek diagnosis than they were five years ago, then conclusion "Thus, either Virginia has become a much more violent and chaotic place over the last fiver years or individuals are more sensitive to violence and chaos than they were five years ago." falls apart.

IMO C

Negation of option C is that individuals with PTSD are more likely to seek diagnosis than they were five years ago, thus suggesting an alternate reason for increased proportion of patients coming to psychiatrists for treatment of symptoms related to PTSD, and therefore smashing the conclusion in the argument. Therefore, option C is the correct answer.

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

A. The number of psychiatric practices in Virginia has not increased over the previous five years...number of psychiatric practices has nothing related to conclusion..Incorrect

B. Individuals with PTSD are no more likely than other individuals to have other psychiatric disorders.....other psychiatric disorders are out of scope..Incorrect

C. Individuals with PTSD are no more likely to seek diagnosis than they were five years ago....negating this statement will falsify the conclusion...Correct

D. Virginia is an exceptionally nonviolent and organised environment....situation of virginia is out of scope...Incorrect

E. Individuals in Virginia do not live in violent and chaotic circumstances any more often now than they did five years ago.....where they used to live is nonsensical...Incorrect

To me C) makes no sense.
Yeah, it is the typical no-brainer answer you are tempted to click after 15 seconds of observing the question, but to me it seemed more like a trap answer.

"... or individuals are more sensitive to violence and chaos than they were five years ago."

This is what the prompt says, the prompt say either x is a reason or y is a reason. Now the answer choice C) basically gives us the same as the prompt does, or doesn't it?
If individuals are no more likely to seek diagnosis than they were five years ago then this whole sensitive argument is out of the race in my opinion.

I don't get it.

My two cents' worth here:

1. An increase in the proportion of people who reported for PTSD treatment does NOT ALWAYS mean that a greater NUMBER of people actually suffer PTSD, which has (according to the passage) resulted from more chaotic times or people being more sensitive to violence.

2. It could mean the same number of people who have always suffered PTSD, but that more people have now come forward to say that they're down with PTSD. That means it is not necessarily the case that these are more chaotic times nor that people are more sensitive to violence, which the argument is structured to imply an increase in the number of people reporting for PTSD (but then again, refer to point 1 - increase in proportion does not mean an increase in the total number of people suffering from PTSD).

3. Since we need to look for a defending assumption i.e. protect the conclusion from being destroyed or attacked fatally, we have to assume that either people are NOT more likely to come forth for PTSD treatment, which means the increased proportion is actually due to more people getting sensitive to violence or that these are indeed chaotic times.

Hence C is the answer.
