I could not get the rigth answer for this question, this came up in a kaplan exam. I also dont understand the explanation. Could someone pick the best answer and explain how to get to it. I will be posting the answer later.


Doctor: Health Maintenance Organizations (HMOs) should not be used to replace traditional fee-for-service methods of delivering health care. The less health care that HMOs deliver, the greater the profit these companies receive. Accordingly, there is a perverse incentive for these companies to deliver very little health care, regardless of the ill patient's needs.

Which of the following, if true, casts the most doubt on the doctor's conclusion?

a)Doctors are paid less by HMOs than they receive under a fee-for-service system, which allows HMOs to charge less for the service they provide.
b)An effective way for HMOs to cut health care delivery costs is to prevent diseases from occurring by providing considerable amounts of preventive health care.
c) If HMOs deliver less health care, competitive pressures will force these companies to lower the rates they charge for health care coverage, returning the profit margin to former levels.
d)Fee-for-service methods of delivering health care have perverse incentives to provide unnecessary health care at inflated costs.
e)HMOs are the only proven way to reduce the high health care costs produced by a fee-for-service system without governmental interference.

a)Doctors are paid less by HMOs than they receive under a fee-for-service system, which allows HMOs to charge less for the service they provide. - This does not attack the underlined claim
b)An effective way for HMOs to cut health care delivery costs is to prevent diseases from occurring by providing considerable amounts of preventive health care. - Again irrelevant, does not attack why they deliver little health care
c) If HMOs deliver less health care, competitive pressures will force these companies to lower the rates they charge for health care coverage, returning the profit margin to former levels - Yes, if HMO's deliver very little health care, it affects their profit margin, hence undermines the bolded claim
d)Fee-for-service methods of delivering health care have perverse incentives to provide unnecessary health care at inflated costs. - This does not concern or attach the Doctor's claim about HMO's
e)HMOs are the only proven way to reduce the high health care costs produced by a fee-for-service system without governmental interference. - Strengthens the argument

Hence the answer which weakens would be C. Hope this helps.

I pick C after a while, I was torn among B, C, D

Arguments:

Conclusion: HMO < FFS
Premise:
- HMO deliver less healthcare, profit rise
- HMO will deliver very little healthcare (therefore we should keep FFS)

We need to weaken HMO < FFS, in this case, the way to weaken is to attack the reasoning

A - Talk about doctor paid, this is just fact, no bearing on the conclusion -> WRONG

B - This is a very appealing answer, but if that is true then HMO still can gain a lot of profit according to the reason of the argument -> not weaken -> WRONG

C - HMO deliver less healthcare, pressure => no more as profit, can't continue deliver less healthcare -> Weaken -> Correct

D - We need to attack HMO, FFS could be bad, but we don't care -> Out of Scope -> WRONG

E - Reduce high cost of FFS, but still gain profit by deliver less healthcare -> not weaken -> WRONG

Just a thought, in hard CR questions almost all choices are identical and seem like good answers.
The best way to go about it is by re reading the conclusion & the premise.
Here it talks about the lack of health care HMO's might provide because of the "incentive" they get for it.

The only statement that directly addresses this is C

Thanks for the explanation Sandeep, although I'm unclear how E strengthens the argument? The argument, very broadly speaking, is that HMOs are not a good alternative. Whilst it doesn't tackle the specific argument (around perverse incentives) and is therefore somewhat out-of-scope, if anything it still weakens the author's implied viewpoint as it provides a positive for HMOs; in terms of the specific argument, it is neutral rather than strengthening.

I chose B for this question because I focused solely on the conclusion (HMOs 'should not be used to replace traditional fee-for-service methods of delivering health care') and not on the specific premise the conclusion was built on (they are bad because 'there is a perverse incentive...'). I think that B, D and E do provide opposing evidence to the author's conclusion and are not therefore 'irrelevant' as they all strengthen the case for HMOs, but they don't weaken the conclusion specifically in the way that C does because they ignore the author's premise, and so C is the answer. However, I would have thought B, D and E could all have been correct answers in the absence of C, given that the question mentions the author's 'conclusion' and not their 'argument' and therefore the answers don't technically need to mention the author's specific premise.

Please point out if there are any flaws in my thinking here? I'm interpreting the takeaway on this problem as 'a statement which weakens the specific premise behind the author's conclusion is preferable to one which weaken's the conclusion without addressing the specific premise.'
