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 his 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.

- i'll go with B. The conclusion assumes mental illness is something that can protected against. (much like a physical disease)

My pick is D.

low levels of immune-system activity tend to score much lower on tests of mental health


Conclusion: immune system protects against mental illness as well as against physical disease. (A causes B)

D is the ony one which says Mental illness does not cause immune system to weaken thus we conclude that immune system weakens mental ability.
Assumption: B doesnot cause A.

The role of the assumption is to hold up the conclusion. In this case, the conclusion is "The researcher concluded from his experiment that the immune system protects against mental illness as well as against physical disease. ". Only B provides the assumption for this conclusion to be true.

D. That's an OG question.

negation works well here. if mental illness does cause subnormal immunity system, then immunity system doesn't protect against mental illness. In the conclusion the immunity system protects against mental illness, in other words keeps/causes it from being lowered.

B. doesn't work well since if we don't assume that mental and physical illnesses are similar, immune system still can provide protection against a mental illness, although the range of immune system's duties will widen (protecting agains two non-similar conditions).

Thanks for the responses.

Right, it's an OG question & like ywilfred I thought it's 'B', but OA is 'D'. I found it difficult to convince myself on 'D'.

What should be the level of this question? Simple, Intermediate or hard on GMAT scoring?

I'll choose D.

B is not correct because it relates Physical illness to Mental illness by the way it effects the body, NOT by how they are caused.
