CR 700--800一题求教！

Bard吟游诗人

The Ergonomic Society conducted a study that indicated that many people develop severe back problems during
adulthood, and that virtually all such people who received chiropractic treatment showed great improvement.
Therefore, in order to minimize the proportion of the population that suffers from back pain, the Ergonomic
Society recommended that chiropractic treatment be directed toward those adults who suffer from severe back
problems. Which of the following is an assumption on which the argument depends?
• Any person who receives chiropractic treatment for back pain may also benefit from other forms of treatment.
• Large insurance carriers cover chiropractic care for back problems to a lesser degree than they do other medical
treatments.
• Individuals who receive chiropractic or other treatment prior to developing severe back problems are not less likely
to develop back pain than those who do not.
• Chiropractic treatment is more effective in treating severe back problems when utilized over a long period of time,
as opposed to sporadically.
• Severe back pain and other problems often cause individuals to miss workdays.

请问楼主是选C 吗？我使用排除法做出来的，本人长难句不是很好...C 选项一开始没get 意思
这是方案题
方案: 得了back pain的人接受chir治疗
目标：减少受back pain折磨的人比例(=治疗back pain)
方案题一定要紧扣 方案和目标，否则都无关
A 得了back pain的人可以从其他治疗方案中获益——和chir方案无关
B chir治疗方案有很多保险---和治疗效果无关
D chir治疗方案长期使用更有效——题目里没有谈及时长对效果的影响，无关
E back pain会导致什么结果——无关

回过头看C选项，直接把not删掉取非：
Individuals who receive chiropractic or other treatment prior to developing severe back problems are less likely
to develop back pain than those who do not.
没有得back pain时，接受过chir治疗的人 更少可能得back pain, 说明chir不是治疗效果，而是预防，对原文W，取非可以W原文的是assumption答案，以上是我的理解~ (但愿确实选C hhh)

hhh 好的，建议有not的选项 在assumption题目中可以直接取非看，会容易一些，然后C选项的prior to=before
