Help on MGMAT CR question

by vsr123 » Fri Oct 19, 2007 9:43 pm
Hi
In the MGMAT test, I came across this CR question.

Advocates insist that health savings accounts are an efficient method to reduce medical expenses. However, widespread adoption of these accounts will soon undermine the public’s health. One reason for this is that most people will be reluctant to deplete their accounts to pay for regular preventive examinations, so that in many cases a serious illness will go undetected until it is far advanced. Another reason is that poor people, who will not be able to afford health savings accounts, will no longer receive vaccinations against infectious diseases.

The statements above, if true, most support which of the following?

A) Wealthy individuals will not be affected negatively by health savings accounts.
B) Private health insurance will no longer be available.
C) Most diseases are detected during regular preventive examinations.
D) Some people without health savings accounts are likely to contract infectious diseases.
E) The causal relationship between an individual’s health and that person’s medical care has been adequately documented.

I would have thought that the answer to this is C , however the correct answer is listed as D


My question - Doesnt that paragraph state that most diseases are detected during regular preventive exams?

MGMAT's explanation is as follows

(C) The author argues that people will not get regular preventive examinations, and will therefore not receive medical attention until diseases are advanced. This logic, even if true, does not allow us to conclude that most diseases are detected during regular preventive examinations.

(D) CORRECT. The argument states that "poor people, who will not be able to afford health savings accounts, will no longer receive vaccinations". Based on this statement, it is reasonable to conclude that some people without health savings are likely to contract infectious diseases.

any help/insight is appreciated

thanks

In my opinion C actually weakens reason # 1.

Incorrect answers to inference CRs often involve a CHANGE IN SCOPE and/or LANGUAGE.
Answer choice C has both.

From the passage: In MANY cases, a SERIOUS ILLNESS will go undetected. Poor people...will no longer receive vaccinations against INFECTIOUS diseases.
Answer choice C: MOST DISEASES.

MANY ≠ MOST:
Many is an indeterminate number; most means MORE THAN HALF.

MOST DISEASES ≠ a SERIOUS ILLNESS or INFECTIOUS diseases:
The passage does not indicate HOW MANY diseases are detected by preventive exams; it says only that in many cases a SERIOUS ILLNESS will go undetected and that poor people will no longer receive vaccinations against INFECTIOUS diseases. MOST DISEASES might not be SERIOUS or INFECTIOUS.

Thus, C is not supported by the information in the passage.

All I can say is that the above sentence says that all poor people cannot afford health savings account. Hence all poor people are prone to get the infectious disease. Hence you can also say that some people from those poor people will contract infectious disease. The possibility is quiet high.

Also in Logical Reasoning, 'All' in the premise can refer to 'Some' in the conclusion. This is what is tested here...


Hope this helps for further understanding...
