Idiom

The writer is trying to include information regarding one of the presenters at the seminar; the phrase must correctly refer back to
            presenters. The pronouns who or whom should be used to refer to people. In this situation, the correct pronoun is whom because an objective case pronoun must be used following the preposition of.

A        One who could only be used after an introductory word such as including

B        One of them who is awkward and ungrammatical

C       And creates the impression that the blind presenter is not part of the group; one of them who is awkward and ungrammatical

D      Correct. This sentence uses the proper objective pronoun
            whom; the phrase clearly conveys the idea of one person out of a larger group.

E       The pronoun which can only refer to objects, events, or unnamed animals; it cannot be used to refer to people

The correct answer is D.

有人说one of whom is blind,是主语presenters的限制性同位语。不过我没有查到过有关用法，从结构上看，one of whom is blind只能充当一个修饰成分，定义presenters，全句结构非常简单presenters will....

one of them is blind   是否正确呢?

one of them is blind是句子在这里不能做同位语，没有同位于名词，D选项，one of whom则强调的是one,Choice D is best: one of whom best serves an appositive to the subject, presenters, because the phrase means "one from among several or many."

之前B错我也想不通，但是ETS说，如果用who就会存在到底是one is blind 还是who is blind的问题Choices B and C are ungrammatical because who competes with one as the subject of is

再琢磨琢磨吧。

感觉用whom 语气要弱一些，符合“one of whom 强调的是 one”。

嗯，这么一说就容易明白了，十分感谢。

那么，改成下面的句子，是否正确？

Presenters at the seminar, that one of them is blind, will demonstrate adaptive equipment that allows visually impaired people to use computers.

呵呵，首先抱歉我语法不是很好阿。。试着用我知道的来解释：

首先，两个逗号之间表示的是一种修饰关系，修饰前面的那个主语，对整句句子影响不大，具体内容一般可以用一些代词引出的或者由“介词（如within\of\above之类）+代词（which\who等等）”结构组成的从句来充当；that引出的似乎没有怎么看到过。。。

另外，我记得好像在逗号后面是不能用that的吧。。。

个人看法，将前面一个逗号去掉后从纯粹语法角度上来说没有问题；但是逻辑关系就体现不出来了：presenters at the seminar 和 one of them被看成了是两个不相关的主语。感觉就好像the sun that the flower is beautiful, is bright.这种样子，怎么看都不顺眼，你又不能说他语法错。

Thank you very much for your patience explanation.
