The GMAT and Related Discussions section is very fragmented in terms of the information available at one's disposal. There are one of reply threads and several other redundant threads that have masked the more important ones.

This is an attempt to make the best of explanations, reasonings, questions etc etc easily available to the junta here. We would be having separate threads for topics such as

Problem Solving (GMAT Problem Solving Discussions) (the existing one is renamed)

Data Sufficieny (GMAT Data Sufficiency Discussions)

Sentence Correction (GMAT Sentence Correction Discussions)

Critical Reasoning

Reading Comprehension. (GMAT Reading Comprehension Discussions)

Please ensure that Q & As are carried out in the repsective threads.

Thread is made sticky

PS:-This post would be edited by the MODS in order to give links to various CRs that would be discussed here. We will try to organise the links for the questions discussed here.
Other relevant posts in the 'one of reply' threads would be moved here

Someone please help me with this question..





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.

I think its B
Because the researcher concludes that the immune system protects against both mental and physical disease.....wheras scores are obtained only of mental tests.....so the assumption is that mental and physical diseases are similar in nature - a fact demonstrated by option B.

Is that the right answer ?...

The conclusion made by the researcher is that

"the immune system protects against mental illness as well as against physical disease"

because people with low levels of immune system activity scored much lower on tests of mental health than people with normal or high immune’ system activity

Suppose the low levels of immune system were due to mental illness, in other words mental illness affected the immune system itself then the scoring on the tests of mental health will come under doubt and eventually the conclusion will fall apart.

Thus the assumption researcher makes is that mental illness does not cause people's immune-system activity to decrease

Option D

Yes we intend to that since many SCs CRs questions have been discussed in that thread and some of them have very good explanations too. But all this would call for time not sure how soon any of the mods would be able to spare that much time but we will try and complete the task in the coming few weeks.

Hello,
I am posting one of the classic critical reasoning problem:
try solving this and know/learn the explanation of the same well.

once you understand such a problem I am sure most of your CR fear is out.

try this:

If A, then B.
If B, then C.
If C, then D.


If all of the statements above are true, which of the following must also be true?


(A) If D, then A.
(B) If not B, then not C.
(C) If not D, then not A.
(D) If D, then E.
(E) If not A, then not D.
