a cr from Gmat

by diebeatsthegmat » Thu Sep 22, 2011 2:09 am
In the next four years, the number of doctors, nurses, and other healthcare workers will increase significantly worldwide. Even so, the average compensation received by such professional will not decline but rather is likely to increase. This is due, at least partly, to the fact that the median age of the world's population will increase steadily in this same period of time.

The argument above depends logically upon which of the following assumptions?

a. The increase in the number of health care workers will be responsible for the increase in the average life span
b. The compensation of doctors and physical therapists who treat the elderly will incrase more than that of other health care workers
c. As a group, older people receive more attention from health care workers than do younger people.
d. Geriatrics, a branch of medicine focusing on the health problems of older people, is the most expensive element of American health care.
e. Increase in the median age of the population will occur in all regions of the world.

as i understand, this CR is that the numbers of doctors and nurses increases >>>health care increases>>>>people getting health care are increase>>>>>>> MEDIAN AGE increass in all over the world... means people will live longer because of increasing of health care
SO i chose A as the answer but its not the right answer and i dunno why.. anybody can please explain?
explain please. dont just give the answer yo chose

Cans,

Again, does it answer the doubt posted?
I don't know who in this forum will be benefited by your post!

Why can't you post your choice with explanation in first place.

Regards,
GK

Even so, the average compensation received by such professional will not decline but rather is likely to increase. This is due, at least partly, to the fact that the median age of the world's population will increase steadily in this same period of time.

The possible assumption IMO, should link the increase in number of doctors etc with the increase in the median age of the population.

a. The increase in the number of health care workers will be responsible for the increase in the average life span --> number of doctors, nurses and other healthcare workers shall increase -- premise. No.

b. The compensation of doctors and physical therapists who treat the elderly will incrase more than that of other health care workers --> Does not matter. irrelevant.

c. As a group, older people receive more attention from health care workers than do younger people. --> kind of matches my assumption before. So probably yes.

d. Geriatrics, a branch of medicine focusing on the health problems of older people, is the most expensive element of American health care. --> ok, but this info needs the assumption that older people are going to avail this treatment. No.

e. Increase in the median age of the population will occur in all regions of the world. --> This would not affect the argument. Why? The median age may increase in some regions of the world and thereby increase the median age for the entire world. Say, if the list {1,4,9,13,15} were to become {1,4,21,34,53} the median increases from 9 to 21 even though all the numbers do not increase in value. Basically ALL is too extreme.

IMO (C). OA?

C does have a small inherent assumption if I am not wrong. More attention to the older group does not necessarily mean that the compensation shall increase but never the less by POE, C is the best choice. Would be glad if someone posted the OE.

This argument exhibits a LANGUAGE SHIFT.
The premise is that there will be an INCREASE IN THE MEDIAN AGE of the world's population.
The conclusion is that there will be an INCREASE IN THE COMPENSATION received by health care professionals.

The argument assumes that these two ideas are connected: that an INCREASE IN THE MEDIAN AGE will lead to an INCREASE IN THE COMPENSATION received by health care professionals.
The argument above depends logically upon which of the following assumptions?
a. The increase in the number of health care workers will be responsible for the increase in the average life span.
No. The argument does not assume that more health workers will lead to a longer life span. It connects an increase in the median age to an increase in compensation. Eliminate A.

b. The compensation of doctors and physical therapists who treat the elderly will increase more than that of other health care workers. No. The argument is not comparing one type of health care worker to another. Eliminate B.

c. As a group, older people receive more attention from health care workers than do younger people. Correct. This answer choice connects older people (an INCREASE IN AGE) to more attention from (implying MORE COMPENSATION FOR) health care workers. C also passes the NEGATION TEST. If answer choice C is reversed, the conclusion is invalidated:

As a group, older people receive LESS attention from health care workers than do younger people.

Less attention = less compensation, which would invalidate the conclusion that the compensation received by health care workers will increase. Since the negation of C invalidates the conclusion, C is the necessary assumption: WHAT MUST BE TRUE for the argument to work.

d. Geriatrics, a branch of medicine focusing on the health problems of older people, is the most expensive element of American health care. Too extreme. For compensation to increase, it is not necessary that geriatrics be the MOST expensive element of health care. Also, the argument is about the WORLD, not just America. Eliminate D.

e. An increase in the median age of the population will occur in all regions of the world. No. The issue at hand is not HOW the median age will increase but whether this increase will lead to an increase in the compensation received by health care workers. For the AVERAGE compensation received by health care workers to increase, it is not necessary that the median age will increase in ALL regions of the world. Eliminate E.

The correct answer is C.

Hi Mitch,

How is the conclusion just about increase in compensation and not anything before it?
