救护车AA的思路

“A recent review of the West Cambria volunteer ambulance service revealed a longer average response time to accidents than was reported by a commercial ambulance squad located in East Cambria. In order to provide better patient care for accident victims and to raise revenue for our town by collecting service fees for ambulance use, we should disband our volunteer service and hire a commercial ambulance service.”

一份西Cambria报纸的社论片断：
最近的对西Cambria的志愿救护服务的回顾显示出其对事故的平均应对时间比设在东Cambria的一个商业救护班要长。为了给事故受害者提供更好的医护服务并通过收取急救服务费来提高我们镇的税收，我们应当解散志愿救护并雇佣商业救护服务。

1 inrepresentative review （West and East）  VS ? Unchanged （West and East）
2 correlation but no casual relationship   （ response time and better patient care ）  VS ? Only one factor?
3 only one factor  (raise revenue <--1 disband 2 hire )   VS? correlation but no casual relationship  

这里各有2种观点分别对同一段论述的。 请问大家赞成哪种观点？

顺便问一下，每篇文章都会发现很多模棱两可的反驳点，就是感觉用这个也可以那个也可以，请问大家如何界定？
