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.
- 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.
- 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.
- Today, more than 43 percent of Californians under the age of eighteen are Hispanic, compared with about 35 percent a decade ago.
- 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.
- 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。

沒有合逻辑的指代是correctiveness的issue, 所有有correctiveness的choices是一定错; 就如A, B, D and E的it.
在这情況下, 只能选C尽管C改变原意。

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~~
- 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.
- 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.
- Today, more than 43 percent of Californians under the age of eighteen are Hispanic, compared with about 35 percent a decade ago.
- 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.
- 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
