还有一题

In Rubaria, excellent health care is available to virtually the entire population, whereas very few people in Terland receive adequate medical care.  Yet, although the death rate for most diseases is higher in Terland than in Rubaria, the percentage of the male population that dies from prostate cancer is significantly higher in Rubaria than in Terland.

 

Which of the following, if true, most helps to explain the disparity between the prostate cancer death rate in Rubaria and Terland?

 

A.    Effective treatment of prostate cancer in its early stages generally requires medical techniques available in Rubaria but not in Terland.

B.    Most men who have prostate cancer are older than the average life expectancy for male inhabitants of Terland.

C.    Being in poor general health does not increase one’s risk of developing prostate cancer.

4. It is possible to decrease one’s risk of getting prostate cancer by eating certain kinds of foods, and such foods are more readily available in Rubaria than in Terland.
5. Among men in Rubaria, the death rate from prostate cancer is significantly higher for those who do not take full advantage of Rubaria’s health care system than for those who do.

   Answer: B

第一道题牛人直接给翻译一下吧...看不懂...

第二道题：其实GMAT也不是说最后的答案一定是最准确的，只是说在五个选项中比较后哪个最好

 A weaken; B 先放下； C 无关； D 无关：题中说的因为这个病死亡率dies from,而选项中说的这个病的risk（几率）；E 无关：在R地区，自己和自己比

第一题：

针对SYSTEM杂志订阅者的调查显示:去年在由于杂志中的广告而下订单的杂志订阅者中，30%为35岁以下的订阅者针对在SYSTEM杂志中登广告的人的调查显示：去年大部分由于看了广告而下订单的读者为35岁以下的读者由此而产生结论：去年由于看了杂志中广告而下订单的读者中，很多都不是杂志的订阅者。

 

偶翻译功底不行哈 大家凑合着看看 我觉得应该是这么个意思

Finding of a survey of Systems magazine subscribers:  Thirty percent

of all merchandise orders placed by subscribers in response to

advertisements in the magazine last year were placed by subscribers under

age thirty-five.

Finding of a survey of advertisers in Systems magazine:  Most of the

merchandise orders placed in response to advertisements in Systems last

year were placed by people under age thirty-five.

For both of the findings to be accurate, which of the following must be

true?

第一句话：对S杂志订阅者的调查显示：去年因为广告宣传而订阅S的所有人中有30%

小于35岁

第二句话：对S杂志广告商的调查显示：去年大部分因为广告宣传而购买S的人都小于

35岁。         

如果以上两项均为事实，以下哪个为真？

分析题目：第一句话和第二句话主要有两个差异点：

1、merchandise orders placed by subscriber和merchandise orders：题目带来的

confusion主要来自这两个概念的混淆，subscribe是merchandise orders的子集，而

非同等概念；

2、30%和most

比较之后不难发现，同样的前提“看广告”和“小于35岁”下，有两个结果，大部分

的人都花钱购买了，但其中只有30%的人订阅===>有很多花钱购买的人并没有订阅。

其他选项比较好排除。

第二题，在利用大家的常识空隙，简单的说在比较两地区病情的同时忽略了其

他的因素。

个人认为是个他因补充解释。

如果人活不到60岁就不会得癌症。

t的人都活不到。所以得不了。
