GWD6-Q18


    

In
California today, Hispanics under the age of eighteen account for more
than 43 percent, compared with a decade ago, when it was about 35
percent.

 

1. In
   California today, Hispanics under the age of eighteen account for more
   than 43 percent, compared with a decade ago, when it was about 35
   percent.
2. Of
   the Californians under the age of eighteen, today more than 43 percent
   of them are Hispanic, compared with a decade ago, when it was about 35
   percent.
3. Today, more than 43 percent of Californians under the age of eighteen are Hispanic, compared with about 35 percent a decade ago.
4. Today,
   compared to a decade ago, Californians who are Hispanics under the age
   of eighteen account for more than 43 percent, whereas it was about 35
   percent.
5. Today,
   Hispanics under the age of eighteen in California account for more than
   43 percent, unlike a decade ago, when it was about 35 percent.

参考答案是C。

我的疑问是，C表达的意思和A是不一致的，改变了逻辑意思。

C：more than 43 percent of Californians under the age of eighteen are Hispanic，指得是18岁以下的Californian中43%是Hispanic。

A：Hispanics under the age of eighteen account for more
than 43 percent，指得是18岁以下的Hispanic占California人口的43%。

以上两个应该不是相同概念的percentage，正确答案的逻辑意思和重心不是要和原文表达的一致吗？
但是其他4个选项，又都有比较概念不对称或代词指代不清问题。

大家讨论一下。

沒有合邏輯的指代是correctiveness的issue, 所有有correctiveness的choices是一定錯; 就如A, B, D and E的it.
在這情況下, 只能選C儘管C改變原意

这个题我看一遍也是用改变原句逻辑方向的方法排除了C。

但是由于其他选项中有明显的比较和It指代问题，所以重新回来思考原句给定的逻辑方向是否一定正确的问题。

在OG和PREP里出现过大概1、2个主句逻辑意思最后是错的这样的情况，想不出是那个题目了。

这也就告诉我们改变愿意，是可以的，但是一定要谨慎。

那么回来看这个题，看A的表达，的确是有问题。Hispanics under the age of eighteen account for more than 43 percent 占谁的43%呢？（猜测一下，如果18岁一下的西班牙人就占了假如说是加利福尼亚人的43%，那么其他年龄段加起来就超过100%了吧）。

而C却将 under the age of eighteen 合理的限制在Californians这里，从语义上看起来更为合理一些。

我觉得lz可能向我一样被误导了。其实A的逻辑含义并不应定是正确的。大多数情况下（我只做了那么一点题），A的逻辑都是对的，但是当有明显错误的时候，就要改了

但貌似A中的情态动词最好还是不要改变为妙~~

1. In California today, Hispanics under the age of eighteen account for more than 43 percent, compared with a decade ago, when it was about 35 percent.
           
2. Of the Californians under the age of eighteen, today more than 43 percent of them are Hispanic, compared with a decade ago, when it was about 35 percent.
           
3. Today, more than 43 percent of Californians under the age of eighteen are Hispanic, compared with about 35 percent a decade ago.
           
4. Today, compared to a decade ago, Californians who are Hispanics under the age of eighteen account for more than 43 percent, whereas it was about 35 percent.
           
5. Today, Hispanics under the age of eighteen in California account for more than 43 percent, unlike a decade ago, when it was about 35 percent.

这个题目很明显的比较的parallel

A hispanics compared with a decade ago

B Of the Californians under the age of eighteen, today more than 43 percent of them are Hispanic,  私下以为 43 percent 后面的of them 可以去掉。整句话有点倒装的感觉

D 后面写得太~

E unlike有悖原来意思

其实 gmat这里 就是 在考 referrence ：

语法上 准确的称谓 是  “照应” 

gmat很喜欢 玩这种花样的。这一点，前人都没讨论过。

43 percent其实是个代词， 任何 出现的 代词 必须 在 上下文中 找到 refer的对象。

A不好，在于 突然 出现了 43 percent，那么 43 percent 没有可以 refer的对象。不可能指代 Hispanics

C就是可以的 more than 43 percent of Californians  43 percent是代词，Californian是 被指代的对象。

这叫做  Cataphoric Referrence

我对这道题的理解是：

意思上，compare前后必须对应

A hispanics和 a decade ago compare,错

B more than 43... 和 a decade ago compare, 错

C 43 percent和35 percent 比，对

D compare 后用to，错

E unlike的比较错

chasedreamho

compare to and compare with has no significant difference in GMAT

我的理解：

A. it 指代什么？Hispanics 和decade也不能比较

B. it指代什么？还有时态have led不对

D. 还是it

E. unlike
