when taking assumption questions in consideration, the easiest way is to find the conclusion and any answer choice if negated weakens the conclusion, that is ur correct answer
the conclusion says: immune system protect mental illness and physical health
d option says that its not the mental illness that causes low immune system--correct option

A researcher discovered that people who have low levels of immune-system activity tend to score much lower on tests of mental health than do people with normal or high immune-system activity. The researcher concluded from this experiment that the immune system protects against mental illness as well as against physical disease.

The researcher’s conclusion depends on which of the following assumptions?

A. High immune-system activity protects against mental illness better than normal immune-system activity does.
B. Mental illness is similar to physical disease in its effects on body systems.
C. People with high immune-system activity cannot develop mental illness.
D. Mental illness does not cause people’s immune-system activity to decrease.
E. Psychological treatment of mental illness is not as effective as is medical treatment.


- The data/premise indicates a correlation.
- The assumption is of causation. Specifically: immune system situation (lets call it X) --> Mental functioning (lets call it Y)
- Hence there are several common assumption: Y-\-> X (negating the possibility to opposite causation), Z -\->X (negating a possible other cause).

[X] - A - the comparison within the group of High/Med immune system is not mentioned - out of scope.
[X] - B - This choice might be tempting. but, when we try to negate, we see the immune system might protect against "things" with different effects on the body.
[X] - C - this answer is too extreme.
[V] - D - fits the Y-/->X common assumption.
[X] - E - Psychological treatment and its effectiveness is out of scope.

My pick is "D".

I used cause and effect relationship between "high immune system" and "low mental illness". Researcher's conclusion says person with good immune system is less prone to mental illness. What if mental illness is the cause of damage to immune system? The conclusion falls apart. Choice D exactly fills the gap.

very simply author wants to say A causes B ,so a potential weakener will be that B causes A the other-way round ,so he assumes that the other way round isn't possible for his conclusion to be true

the portion you yourself mentioned that "why is it not true that if there is mental illness there is a chance that immune system is low. thats why he is scoring low on mental health." is an assumption he assumes that this fact is not true and option D states the mental illness is not the cause of low immune levels but the other way round

D is the answer

Byrce Wayne: Alfred I need Poison Ivy because I am ill.
Alfreddo: Maester Wayne you are ill because you had Poison ivy.

Option D works along the same lines. It may be that mental illness that has reduced immunity.

D is the answer.

if you guys have read POWERSCORE CR bible then you are going to understand what i am writing below.

this type of assumption questions are DEFENDER type. in these type of questions the answer choice will try to defend the argument conclusion.

the conclusion here in the argument is:

The researcher concluded from this experiment that the immune system protects against mental illness as well as against
physical disease.

or in short

immune system -->> protects against mental illness and physical too.


option D read as:

D. Mental illness does not cause people’s immune-system activity to decrease.

this statement defends the argument that the reverse is not true( its defending the argument)

hope it helps

I guess that this question got me (and probably other non-native speakers as well) because I misunderstood how "as well as" is being used.

Conclusion is: "The researcher concluded that the immune system protects against mental illness as well as against physical disease".
If you understand is as: the immune system protects against mental illness and
the immune system protects against against physical disease
then indeed answer B is tempting.

But If you understand it as:
The researcher concluded that the immune system protects against mental illness in addition to/besides the fact that it protects against physical disease" (and that fact was previously known?)
then it's clear D.

Can someone check this? Maybe I just made this up and B is wrong for other reasons? (i.e. even if mental illness and physical disease weren't similar, immune system could still protect against them both?) :-D

A researcher discovered that people who have low levels of immune-system activity tend to score much lower on tests of mental health than do people with normal or high immune-system activity. The researcher concluded from this experiment that the immune system protects against mental illness as well as against physical disease.

This is a cause and effect assumption problem, where is X causes Y. So the assumption is that Y does not cause X. It's mentioned in Manhattan book.

The researcher’s conclusion depends on which of the following assumptions?

A. High immune-system activity protects against mental illness better than normal immune-system activity does.
We are not comparing between high immune system or normal immune system.

B. Mental illness is similar to physical disease in its effects on body systems.
We are not concerned with the effects of it.

C. People with high immune-system activity cannot develop mental illness.
The conclusion is that immune system as whole protects against the mental illness and against physical disease. Not high immune system or low immune system.

D. Mental illness does not cause people’s immune-system activity to decrease.
Well this is stated in the premise that immune system disbalance cause mental illness and so is in the conclusion. Refer to the cause and effect relation.

E. Psychological treatment of mental illness is not as effective as is medical thereabout its effectivness.
We are not again not concerned about the effectiveness.

D. Mental illness does not cause people’s immune-system activity to decrease.
E. Psychological treatment of mental illness is not as effective as is medical treatment.


The answer is D

Premise 1
:A researcher discovered that people who have low levels of immune-system activity tend to score much lower on tests of mental health than do people with normal or high immune-system activity.

Conclusion
: The researcher concluded from this experiment that the immune system protects against mental illness as well as against physical disease.

D says that the reason for the poor mental health test is low immune system activity .
If this is not true then the argument falls as low level of immune activity is caused by poor mental health and the conclusion drawn would be wrong

The researcher concluded from this experiment that the immune system protects against mental illness as well as against physical disease.

Conclusion : Immune system protects against mental illness as well as against physical disease.
A. High immune-system activity protects against mental illness better than normal immune-system activity does. >> Does not address the conclusion and researcher is not relying on a comparison between high and normal immune system
B. Mental illness is similar to physical disease in its effects on body systems. >> Irrelevant
C. People with high immune-system activity cannot develop mental illness. >> Does not address conclusion.
D. Mental illness does not cause people’s immune-system activity to decrease. >> Applying assumption negation, this would remove the entire evidence for conclusion basis i.e. If mental illness causes people's immune-system activity to decrease, then we cannot draw the conclusion from the experiment that immune system protects against mental illness.

E. Psychological treatment of mental illness is not as effective as is medical treatment. >> Irrelevant

man, I jump to choose B with the outside knowledge. B actually says about the same IMPACT of mental illness and physical diseases.
=> D is right and D is a common pattern, the causal relation only happens in one way.
