Sergeant
Our police academy no longer requires its applicants to pass a physical examination before being admitted to the academy.As a result,several candidates with weak hearts and high blood pressure have been admitted.Hence,we can expect our future police force to have more health problems than our current police force.
Knowledge of each of the following would be relevant to determining the reliability of the sergeant's prediction EXCEPT whether
(A) police officer candidates are screened for high blood pressure before joining the police force
(B) the police officer candidates who are not healthy now are likely to be unhealthy as police officers
(C) graduates of the police academy are required to pass a physical examination
(D) the health of the current police officer candidates is worse than was the health of police officer candidates in the past
(E) a police officer's health is a reliable indicator of the officer's performance
请问这题C为什么不对

这段话的意思是“警察学院不再要求报名者录取入院前通过身体检查,结果是个别的心脏不好并患有高血压的报考人被录取.因此,我们可以认为未来的警察部门会比现在出现更多的健康问题”.


　　段落中提供的信息several candidates withweak hearts and high blood pressure have been admitted（个别的心脏不好并患有高血压的报考人被录取）,可以认为报考人入院前并不是不考虑身体条件,只是不再要求通过院方的身体检查.


(C)  项指警官学校的毕业生要求通过身体检查,上面的段落中并没有涉及到.


　　以下选项都与本段话有关：


(A) 项指有些“警官报考人在加入警察部门前隐瞒了自己的高血压”,言外之意是因此其中个别人被录取；
(B) 项指有些现在不健康的报考人可能将来作为警官也是不健康的,言外之意同上；
(D) 项指当前警察部门的健康情况比过去警官报考人更差,这一点符合个别人被录取的事实
(E) 项指警官的健康是结构执行任务的可靠指标,这一点符合上面段落中隐含的内容.

Hastings‘ contracture is a disorder of the connective tissue in one or both hands, most commonly causing loss of mobility. H痉挛是一只或者两只手组织的连接错位，经常会导致活动不便。A survey of thousands of medical-insurance claims found that over 30 percent of people who had one hand operated on for Hastings'contracture underwent surgery a second time for this disorder within three years.一项研究了上千份的医疗保险索赔单的调查发现，超过百分之三十的人有一只手进行过H痉挛的手术，并且在三年内进行过两次。 Clearly, therefore, a single surgical treatment of Hastings' contracture is often ineffective at providing long-term correction of the disorder很明显的，因此，对于H痉挛，一次手术治疗不能保证其长期的错位纠正。
Which of the following, if true, most seriously weakens the argument?下列如果是真的，哪个最能削弱论点。
(A) The medical-insurance claims did not specie whether the surgery was on the patient's right or left hand. 医疗保险索赔没有明确出到底是病人的左手还是右手做过手术。(B) The surgical techniques used to treat Hastings' contracture are identical to those used successfully to treat certain work-related injuries to the hand. (C) A separate survey found that 90 percent of patients operated on for Hastings' contracture report increased hand mobility within one month after the surgery.另一份研究发现90%的病人接受过H痉挛手术在手术后1个月内手的痉挛有改善。 (D) All of the patients in the survey were required by their insurance companies to seek a second opinion from a qualified surgeon before undergoing the operation.所有调查的病人，在进行手术前，保险公司都要求他们向优秀的外科医生询问建议。 (E) Many people who have Hastings' contracture choose to tolerate its effects rather than undergo the risks of surgery.
答案是A，CD为何不对呢？排除它因？
个人觉得，选A是因为有可能那百分之30的人都是双手痉挛，所以第一次手术是左手，第二次是右手，再说以，结论就不能说，一次手术是不能长期有效的。
C项，1个月内有改善，但是没有说之后怎么样，有可能三年内还要继续做手术，所以不影响结论：一次手术不能长期有效。
D项，其实我觉得这完全不会影响结论啊~
可以交流一下啦，都是个人意见
真的是很难的题
满意请采纳。
