I thought of this as a Demand-Supply problem.

It states that the supply of resources (doctors, nurses etc.) is expected to increase. The increase in supply tends to decrease the price (compensation/salary). However, as it states, the average compensation is not expected to decline instead likely to rise.
The above scenario (increase in supply and simultaneous increase in price) can only happen if the demand (of healthcare services) also increases.
Now, it tries to explain the above scenario (increase in supply and simultaneous increase in price) by saying that this is due to (at-least partly) increase in median age.
However, an increase in median age does not link-up with the demand thing unless it can be deduced that the increase in median age is likely to increase demand (of healthcare services).

Option C exactly says that.

a. The increase in the number of health care workers will be responsible for the increase in the average life span: Out of Scope
b. The compensation of doctors and physical therapists who treat the elderly will increase more than that of other health care workers: Its a partial answer, talks about only doctors and physical therapists...not about nurses and other health care professionals
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. : It assumes that only this medicine is used by people...which might not be correct
e. Increase in the median age of the population will occur in all regions of the world. : Clearly out of scope

Hi Guys, this is my first post on gmatclub and i hope my reasoning goes well

C seems to go well with the negation technique compared to B.

Highlighted the connected key parts of assumption, premise and conclusion.

Premise :
1)In the next four years, the number of doctors, nurses, and other health care workers will increase significantly worldwide.
2)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.-- Note: Population is not increasing just the ratio of population from median to young will increase compared to before.

Conclusion : Even so, the average compensation received by such professional will not decline but rather is likely to increase.

(B) The compensation of doctors and physical therapists who treat the elderly will increase more than that of other health care workers
Negation : The compensation of doctors and physical therapists who treat the elderly will NOT NECESSARILY increase more than that of other health care workers
Still the conclusion can hold true even if the salary of doctors(specialist for elderly) & therapists don't increase more than other health care workers, the salary can still increase at the same level par with other health care workers and overall average can go high due to more demand of all healthcare services. Conclusion still holds true after negation.

(C) As a group, older people receive more attention from health care workers than do younger people.
Negation : As a group, older people NOT NECESSARILY receive more attention from health care workers than do younger people.
IF the ratio of median to young is increasing and the old people dont necessarily need more attention than young -> Situation should be BAU and it should not lead to increase in the no of workers and their demand and the average salary.
Conclusion fails in this negation case.

Ans seems to be C.

Kindly review.

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 increase 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.

The argument starts by saying that in the next four years X,Y,Z will increase. In contrast to the supply demand theory, the compensation is expected to go up. and the cause of this effect, partly, is due to the fact that median age of the world's population will increase during that time.

So even though the number is increasing, the salaries are not going down. Which in turn suggests the supply is going up the demand is also going up. This can create a situation where the compensation is higher. Another assumption is that as the median age increases then healthcare required also increases. So something that addresses these issues can be a possible answer.

A - Average life span is not discussed in this argument .. Hence Out of Scope
B - This comparison is uncalled for and therefore irrelevant for the sake of the argument
C - This point states that as the median age increases, i.e., older folks, the care required also increases .. A possible answer
D - Geriatrics is not discussed and hence is out of scope
E - Median age worldwide is considered and therefore it is irrelevant for the sake of the argument if the median age increases in all regions.

Based on the points above, I choose C as the answer for this CR.

Cheers !!

I arrived at C as a general fact about the difference between health problems between young and old age population. This also connects to the fact about increased Median age of world's population

Why not E the right answer?

I feel C not to be the right answer supporting the argument.

A, B & D are Out of Scope

E .: According to the last statement in the argument "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." we can say that it depends on the E statement.

C: No direct evidence relying on this statement

In the next four years, the number of doctors, nurses, and other health care 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
argument says increase in older population is the cause for increase in the number of healthcare professional and hence their average compensation. But the option just reverses the cause -effect. Hence incorrect.
(B) The compensation of doctors and physical therapists who treat the elderly will increase more than that of other health care workers
Apply negation technique - The compensation of doctors and physical therapists who treat the elderly will not increase, but what if that of other HC workers increase. Argement still holds true.
(C) As a group, older people receive more attention from health care workers than do younger people.
Apply negation - older people do not receive more attention from health care workers than do younger people.
and the argument falls apart.

(D) Geriatrics, a branch of medicine focusing on the health problems of older people, is the most expensive element of American health care.
Argument discusses compensation of HC professionals but this option talks about expensive branch of medicine..that too in America.
(E) Increase in the median age of the population will occur in all regions of the world.
Already stated in the argument. Hence can't be an assumption.

The source for this question is Kaplan's GMAT course - I have taught this one about 20 times in the past 6 years. Like many other questions (whether they are Kaplan, Manhattan, or real GMAC questions), the question becomes quite a bit simpler when you start by understanding the conclusion of the argument as specifically as possible. In this case, the conclusion is "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." It is critical to see that this conclusion is in fact a claim of causality: The arguer wants us to believe that one of the reasons why health care professionals will earn more (worldwide!) is the fact that the median age of the population will go up (worldwide). So we need an assumption which will help to justify this causal claim.

From this perspective, A is obviously no help; it makes age the effect, and the argument is trying to make age the cause. Longer life span and older median age are not the same thing anyway. B does not help because it ASSUMES that everyone's compensation will go up, although by different degrees, but does not give any reason why an older median age would drive it up. C gives a reason for an older median age to cause a demand increase, which could in turn cause compensation to go up. D does nothing, because its scope is the US only; because the higher expenses could easily relate to drugs and equipment, NOT to professional compensation; and because BEING more expensive does not mean that large numbers of people will USE the service. E does not help because we already know that the median age is increasing; the question is not the distribution of this increase, but why it would lead to higher pay for workers.

This reinforces a guideline that I think is important: When an argument makes a CAUSAL conclusion, make SURE that you see the causality. Once you notice that causality is the issue, it really narrows down the possible ways to support or refute the claim.

Hi,

To find out the assumption, we first need to find out the premises and the conclusion to locate the gaps.

Premise: In the next four years, the number of doctors, nurses, and other health care workers will increase significantly worldwide.
Premise: median age of the world’s population will increase steadily in this same period of time
Conclusion/Prediction: the average compensation received by such professional will not decline but rather is likely to increase

I think some of the confusion could have been in identifying the conclusion. It's not stated directly using keywords like therefore, as a result etc.

Rather, it's written in a counter observation style "Even so,...". This makes it quite tricky to identify it as the conclusion. However, reading the third statement gives us a clue that the second statement is indeed a conclusion. This is because the third statement tries to explain the second one, while the first statement is treated more or less a factual or certain statement.

Now, after the conclusion has been identified, we can either move directly to the options or pre-think what could be an assumption. The strategy advised by e-GMAT is pre-thinking.

So, let's try to pre-think an assumption:

It says that number of workers will increase and the conclusion is that their average compensation will also increase. We know that increase in compensation could either be the result of increased number of work hours or increased payment per hour. So, older people should either provide more work to these workers or provide more payment for the same amount of time. The first part i.e. more work, is what is given in option C. Therefore, this is the correct choice.

For completion, let's look at other choices too:

(A) The increase in the number of health care workers will be responsible for the increase in the average life span - Incorrect. No confusions.
(B) The compensation of doctors and physical therapists who treat the elderly will increase more than that of other health care workers - We are talking about doctors, nurses and other healthcare workers as a group in the passage while this statement treats them differently. This statement will not even fit in the argument. Incorrect.
(D) Geriatrics, a branch of medicine focusing on the health problems of older people, is the most expensive element of American health care. - We are not talking about America specifically. Incorrect.
(E) Increase in the median age of the population will occur in all regions of the world. - What if this doesn't occur and only Japanese age? Can't workers salaries increase in that case? If salaries in rest of the world remain constant while salaries in Japan rise, average salary will increase. Since negation of this statement doesn't invalidate the conclusion, this is not an assumption.

Hope this helps

Let me know if further clarity is required.

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

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.

Explanation (I don't fully understand):
Since the number of healthcare workers are on the rise along w/ the average compensation, the answer is supported by the rise in the number of elderly people. More workers will get more money, so it is assumed that the elderly are especially likely to require services of healthcare workers.

anyone that got the correct answer have a better explanation?

cant understand the explanation

Compensation will increase for healthcare workers, doctors and nurses even if their labor supply has increased.
Then, it goes to explain because the median age of the world's population will increase.

This sounded like these group of people's increase has affected the compensation to increase. Well, sounds like more poeople need these healthcare people...

(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 increase more than that of other health care workers
Well the healthcare people are taken as one group...

(C) As a group, older people receive more attention from health care workers than do younger people.
This seems to explain the group of people that has increased in number and who needs medical attention more...

(D) Geriatrics, a branch of medicine focusing on the health problems of older people, is the most expensive element of American health care.
extreme... no where that the most expensive element was assumed in the argument...

A) Here we are discussing the compensation of doctors, nurses and other health care workers as a whole and not that of only other health care workers.

B) same as above

C) Correct. As the population gets olders it requires more attention so the demand for service provided by these professionals would increase and so is their compensation.

D) No any connection between medicines and health care professionals

E) Not relevant

Chiranjeev,

I agree that all except C are not answers.

But still difficult to understand why C is answer...

C says Older people "receive" more attention from health care workers....!! don't you think it should be "require" instead of " receives"??

Because IMO C option means workers pay more attention towards older people than younger people...!!
