Page: 536

Between 1975 and 1985, nursing-home occupancy rates averaged 87 percent of capacity, while admission rates remained constant, at an average of 95 admissions per 1,000 beds per year. Between 1985 and 1988, however, occupancy rates rose to an average of 92 percent of capacity, while admission rates declined to 81 per 1,000 beds per year.

If the statements above are true, which of the following conclusions can be most properly drawn?

(A) The average length of time nursing-home residents stayed in nursing homes increased between 1985 and 1988.

(B) The proportion of older people living in nursing homes was greater in 1988 than in 1975.

(C) Nursing home admission rates tend to decline whenever occupancy rates rise.

(D) Nursing homes built prior to 1985 generally had fewer beds than did nursing homes built between 1985 and 1988.

(E) The more beds a nursing home has, the higher its occupancy rate is likely to be.

(A) The average length of time nursing-home residents stayed in nursing homes increased between 1985 and 1988.
I think this explains the discrepancy properly. Although admission rates declined, the average length of stay increased and this phenomenon leads to increased occupancy rates.

(B) The proportion of older people living in nursing homes was greater in 1988 than in 1975.
First of all older people are not discussed in passage, and secondly they constitute just a part of entire patients and not the complete part. Moreover this is not discussed in passage above so no conclusion of this sort can be drawn.

(C) Nursing home admission rates tend to decline whenever occupancy rates rise.
Although this can be a plausible conclusion but there is no relationship shown between increased admission rates and declining occupancy rates.

(D) Nursing homes built prior to 1985 generally had fewer beds than did nursing homes built between 1985 and 1988.
Hospital capacity is not discussed in passage above so no conclusion of this sort can be drawn.

(E) The more beds a nursing home has, the higher its occupancy rate is likely to be.
Hospital capacity is not discussed in passage above so no conclusion of this sort can be drawn.

So Answer is A.

C is the best conclusion from all the choices. You either have more elderly people during 85-88 OR you have nursing home closed down due to bankruptcy (for example). Whatever the case, when there is a short supply of nursing home rooms, it is harder to get into a nursing home. Similar to elite business schools, many people want to get in = low admission rate.

In A, there is no evidence to support this from the passage.

In B, Not discussed in the passage

In D, not mentioned in the passage

In E, seems contrary to the passage

U can reject B because of the presence of the word "older".We are concerned with the occupancy duration and not the age of the occupants.If the Occupancy duration increases then the occupancy will increase without there neccesarily being an increase in the rate of admissions.

+1 A

However, I believe the question is not well constructed.
Be careful of 1000 CR questions. Most of them are not GMAT type.

(C) is incorrect because the stimulus never indicates that this is a common trend. It's simply saying 'this is what happened between these two points in time'. There's nothing in the stimulus to suggest that because X happened between 1985 and 1988, that X will also be true between y and z.

I chose A using POE. B has 'older' which is not specified anywhere in the question. Others are out of scope IMO.

The argument is basically stating that over two different time periods, occupancy rates in nursing homes increased. However, during those same time periods, the admission rates at the nursing homes decreased. The question asks us to find an answer that Resolves the Paradox (the question stem says "Find the Conclusion" but the conclusion is actually resolving the paradox)

(A) The average length of time nursing-home residents stayed in nursing homes increased between 1985 and 1988. - This helps explain why the occupancy increased (people stayed in nursing homes for a longer duration). This also explains why admission rates decreased (Less people stayed for a longer time occupying more number of beds). CORRECT ANSWER.

(B) The proportion of older people living in nursing homes was greater in 1988 than in 1975 - Older people not mentioned in the stimulus. So, a definite conclusion about them cannot be drawn.

(C) Nursing home admission rates tend to decline whenever occupancy rates rise. - As already pointed out above, just two time periods are taken into consideration in the stimulus. Those two time periods need not be representative of the entire truth in general. Thus, this statement, drawn as a generalization, may not necessarily be true. This option, IMO, is more of a real-world-true scenario and that is why a trap.

(D) Nursing homes built prior to 1985 generally had fewer beds than did nursing homes built between 1985 and 1988. - Not necessarily true. Does not resolve the paradox.

(E) The more beds a nursing home has, the higher its occupancy rate is likely to be. - Maybe real-world-true but not necessitated by the premises. A definite conclusion cannot be drawn.

I doubted between A and C.

I discarded C because of this unclear sentence: "Between 1975 and 1985, nursing-home occupancy
rates averaged 87 percent of capacity, while admission rates remained constant, at an average of
95 admissions per 1,000 beds per year."

However, I agree with some of the observations about this option made above.

(A) The average length of time nursing-home residents stayed in nursing homes increased between 1985 and 1988. - Correct.

(B) The proportion of older people living in nursing homes was greater in 1988 than in 1975. - Incorrect. Out of scope. Older people is not even the context.

(C) Nursing home admission rates tend to decline whenever occupancy rates rise. - Incorrect. A broad generalization. Need not be true always.

(D) Nursing homes built prior to 1985 generally had fewer beds than did nursing homes built between 1985 and 1988. - Incorrect. We cannot ascertain the number of beds from the given info

(E) The more beds a nursing home has, the higher its occupancy rate is likely to be. - Incorrect. Out of context.

Going with A..
A-correct---
B- we cant comment on older person proportion
c-With only one scenario , we can conclude this biased result
d-out of scope
e-same as c.

Occupancy rate at a given time = No. of beds occupied / total number of beds.

We know that the occupancy rate has increased, from 87% to 92%.

three possibilities emerge -
1. The number of patients who are admitted has increased and hence the number of beds occupied also increases
2. The number of patients has remained the same, but the number of beds has reduced.
3. Patients spend more time being admitted. This leads to an increase in occupancy rates even though the other factors may not have changed.

Now, we are told that admission rates have decreased, from 95 per 1000 beds to 81 per 1000 beds.

Admission rates = No. of patients admitted / total number of beds.

We can rule out possibility 1 because if this quantity increases then the total number of beds has to increase much more (because the admission rates drop).
If the number of beds increases much more than the number of patients, then the occupancy rate will drop, not increase.

We can rule out possibility 2 because if the number of beds has reduced then the average number of patients admitted should decrease much more (because the admission rates drop).
If that is the case, then occupancy rates will not increase, as the numerator decreases by a higher proportion than the denominator

We are left with possibility 3. Which answer option states this? Option A.

B - Incorrect.
We are concerned with the entire population, not just with older people. Also, we are referring to periods, not one particular year.

C - Incorrect.
We cannot draw this conclusion from just two data points about two periods.

D - Incorrect.
We cannot conclude about individual nursing homes. Also, from the discussion above we cannot infer anything about the number of beds.

E - Incorrect.
We cannot conclude this based on just 2 data points.

this is a common pattern in gmat, the inference is that after a period, the length of objects increase.
an another example is the jail and prisoners.

also, test takers should not spend too much time on reading the question. I still have struggles with reading the question.

C is incorrect because there is no causal relation between the increase and the drop.

I was a little confused but I think I can see where I was wrong.

I broke it down to:
Premise 1: from 1987-1985, occupancy was 85%, admission rates were 95/1000 beds
Premise 2: from 1985-1988, occupancy was 92%, admission rates were 81/1000 beds

So it appears there's a discrepancy but first and foremost the focus (since it's an inference type question) is to look for what we can conclude from this statement.

(A) states that between 1985 and 1988, people stayed longer in nursing homes. This one made a bit of sense but I wasn't too sure yet so I moved on to the next one.
(B) While this one seems tempting the biggest issue is that it brings up older people living in nursing homes, which we can't assume from the statements; the only figures presented were about occupancy and admission rates.
(C) it's too broad of a generalization. We can't say this is always true.
(D) even if the number of beds increased, the facts we were given were rates, not a headcount of admission. An increase in the number of beds alone has no bearing upon the rates of admission
(E) This seems like a reverse of answer choice C, and it is tempting. However there is nothing that describes an increase in the number of beds in the question. Had there been a description of an increase, this one may have been the answer.

By eliminating the remaining answers, it looks like A is the best one. On the other hand, PoE is a pretty slow strategy when pressed for time so... maybe there's a better explanation as to why A is the best answer?

the pattern in this question is that over a period of time, one thing is higher while the other thing is lower. What is the inference?
Clearly, the question deals with the evidences, not premises.
Only A is correct.

Hi abhimahna, GMATNinja,
I am having a doubt here, No where in the stimulus he stated that Total number of nursing homes remained constant. What if the Total No. Of nursing homes declined after 1985, Increasing the occupancy rates ?
Then we can not infer it right. If we want to infer anything, then it must be true and we should not assume anything more than what the passage has given. Can you please explain me what am i missing in this question. Because of this thought process i could not get any answer right in the given options.

Thank you
MBA Aspirant.
