请教LSAT-7-1-8

Coherent solutions for the problem of reducing health-care costs cannot be found within the current piecemeal system of paying these costs. The reason is that this system gives health-care providers and insurers every incentive to shift, wherever possible, the costs of treating illness onto each other or any other party, including the patient. That clearly is the lesson of the various reforms of the 1980s; push in on one part of this pliable spending balloon and an equally expensive bulge pops up elsewhere. For example, when the government health-care insurance program for the poor cut costs by disallowing payments for some visits to physicians, patients with advanced illness later presented themselves at hospital emergency rooms in increased numbers。

我来试一下,不知道对不对:

这个题除了第一句之外,后两句我也不全明白.但是三句话之间的关系还是比较清楚.

Statement 1: piecemeal 的体系不能彻底降低成本.

Statement 2: 解释statement 1 的原因。客观上,support statement 1.

Statement 3: an example of statement 2.

如果把这三句作为一个完整的argument, statement 1 should be regarded as the conclusion.

这样一来的话，作为piecemeal system对立面的comprehensive approach当然就值得我们一顶了。所以答案A 就出来了。需注意的是: if 'could' in answer a were replaced by 'will' or 'must', then we should hesitate upon it.

至于其他答案为啥错（或许说是‘不如A 好’），我也不明白。反正是我一上来就瞄上A了。其他几个答案也没看。

可能上面的分析也是错的，请看帖的弟兄们批判阅读吧。
