50. As a baby emerges from the darkness of the womb with a rudimentary sense of vision, it would be rated about 20/500. or legally blind if it were an adult with such vision.
(A) As a baby emerges from the darkness of the womb with a rudimentary sense of vision, it would be rated about 20/500, or legally blind if it were an adult with such vision.
(B) A baby emerges from the darkness of the womb with a rudimentary sense of vision that would be rated about 20/500, or legally blind as an adult
(C) As a baby emerges from the darkness of the womb, its rudimentary sense of vision would be rated about 20/500; qualifying it to be legally blind if an adult
(D) A baby emerges from the darkness of the womb with a rudimentary sense of vision that would be rated about 20/500; an adult with such vision would be deemed legally blind.
(E) As a baby emerges from the darkness of the womb, its rudimentary sense of vision, which would deemed legally blind for an adult, would be rated about 20/500.
In choice A, it, the subject of the main clause, seems to refer to baby, the subject of the subordinate clause; thus, A seems to state that the newbom baby, rather than its sense of vision, would be rated 20/500[t1] . Similarly, choices B and E use awkward and ambiguous phrasing that suggests that the sense of vision, rather than an adult with 20/500 vision, would be considered legally blind. C incorrectly uses the semicolon, which should separate independent clauses, to set off a verb phrase. The phrase if an adult in C is also illogical, since it states that a baby could also be an adult. D is the best choice.
请问划线部分的解释该如何理解，为什么说if adult有“婴儿可能是大人”的歧义

查过旧贴了,没有这个问题解答呀
顶,
有没有人知道,谢谢各位大侠了
qualifying it to be legally blind if an adult
OG是先说这不是个完整的句子，然后暗示说，就是对也等于：
qualifying it to be legally blind if (it is) an adult. (if后只能省it is，因为to be legally blind的逻辑主语是it）
如果你同意我上面的分析的话，it指代the baby，就变成if the baby is adult了。
仍然疑惑````
为什么if 后面不是省略的一个虚拟语态it were呢？ 如果是这样省略不也很想得通么？
求赐教

不通: qualifying it to be legally blind if (it were) an adult --> ....如果it(baby)是adult
对啊```` THX
我也有这个疑问。
但是，从代词指代应该没有歧义的角度上看。前面的那个it有可能被认为指代senses是把。
这样就产生了歧义了。
而且，c关键错在‘；’后不是个句子。
而且，gmat里我见得较少看这种情况下，考察虚拟语气的。
但是，还是想请那位大n给吓个结论。

个人看法：只有baby才能to be blind吧，因此，我想这里的解释it应该暗指baby而非sense.其余同anyname同学所言。
这里A ,C,E选项中的AS的用法正确么，OG解释中并未提到这一点
个人感觉是不太对的
另外 WOULD BE RATED ABOUT 为什么要用虚拟语气呢
RATED ABOUT 20/500 是习语么

as正确,作为连词引导时间状语从句,意思是当baby出生的时候.....
50. As a baby emerges from the darkness of the womb with a rudimentary sense of vision, it would be rated about 20/500. or legally blind if it were an adult with such vision.
(A) As a baby emerges from the darkness of the womb with a rudimentary sense of vision, it (sense of vision)would be rated about 20/500, or legally blind if it (baby)were an adult with such vision.it指代不情
(B) A baby emerges from the darkness of the womb with a rudimentary sense of vision that would be rated about 20/500, or legally blind as an adult vision is legally blind:illogical
(C) As a baby emerges from the darkness of the womb, its rudimentary sense of vision would be rated about 20/500; qualifying it to be legally blind if an adult 1 ;后面应该用完整主谓结构2
if后面省了了主语,则应该与主句主语一致.则是it :baby
(D) A baby emerges from the darkness of the womb with a rudimentary sense of vision that would be rated about 20/500; an adult with such vision would be deemed legally blind.
(E) As a baby emerges from the darkness of the womb, its rudimentary sense of vision, which would deemed legally blind for an adult, would be rated about 20/500.
vision, which would deemed legally blind illogical
关于OG的解释,我是这样理解的.
C的错误原因两个:一个,分号用错,后面应该是独立的句子;另一个就是
if an adult 在 C中 是不符合逻辑的,因为如果这样就理解为,如果一个新生儿是一个大人.而, 这不是原文的意思.原文的意思是,如果新生儿视力为20/250的是很正常的,但是如果一个大人的视力是这么多,那么这个大人就是盲人了.
希望指教!
E选项中which怎么指代不清了？which不就指代vision么？是不是E得主要错误还是vision不能would deemed legally blind for an adult
which引导非限定性定从的时候，修饰的是就近单元的its rudimentary sense of vision中的主词rudimentary sense了，所以就不对了吧~~

which 引导非限定的定语从句,修饰vision(或者修饰sense,不争论),表达一个全局的概念,一个属性.也就是在说"所有的vision(或者sense)都会被认为blind,明显不合理
所以这里应该用that引导限定的.
至于是修饰vision还是sense不重要,反正逻辑上都不对.
这题无法从动词上[判断which到底修饰谁,但是我认为是vision
