I would like to ask one particular doubt that is simple but yet to settle down for me.
In the above example you quote "My wife, who is extremely kind and generous, volunteers every Monday at a homeless shelter." Here, "who" serves as subject within the non-essential clause and so it is followed by verb "is".
In the 2nd example that you quote "My wife, to whom I send flowers every day, is a wonderful person." , here in non-essential clause "whom" is the object of preposition, but the subject is "I" and the verb is "send".
Whereas in the OA, i.e., D "one of whom" is blind; what is the subject for which "whom" is required to be used as receiver of the action. Cant we consider the non-essential clause with a subject pronoun such as - "one who is blind".
I know you are a very busy person, but I hope you reply me as early as possible as next week I am having my exam.
Thank You.
Apologies for the slow response! I'm obviously too late to be helpful for you, but if it's any consolation, this particular issue is extremely rare on the GMAT.
Anytime we have a plural subject and want to modify some portion of this larger group, we'll introduce a phrase like "one of whom," or "some of which" to differentiate between the larger subject of the main clause and the smaller subject of the modifying clause. For example, "The paintings in the Louvre, one of which was defaced by a toddler with a paint gun, proved to be a disappointment to the tourist from Queens." The phrase "one of which" differentiates between the painting that was defaced by the toddler and the larger group introduced in the subject of the sentence.
However, the sentence "The paintings in the Louvre, one which was defaced by a toddler with a paint gun, proved to be a disappointment," isn't acceptable usage. A native speaker would instinctively feel that something is off about this construction, but the reason it's objectively problematic is that it's confusing. One of
what? Without the "of" it's not entirely clear that I'm talking about a member of the group in the subject. Perhaps I've introduced a new group. At the very least, you'd have to reread the sentence a couple of times to get a handle on what the writer is trying to communicate, and on the GMAT, clarity trumps murkiness every time.
The same issue applies to your question. If we have "Presenters at the seminar, one of whom is blind..." the phrase "one
of whom" indicates that we're talking about a member of the original group of presenters. If we have "Presenters at the seminar, one who is blind" it's not entirely clear that the "one" is a member of a larger group -- it's a confusing phrase, and it almost sounds like the seminar is blind.
I hope that helps!
