OG #19 (verbal review purple book)
While depressed property values can hurt some large investors, they are potentially devastating for homeowners, whose equity - in many cases representing a life’s savings - can plunge or even disappear.
By the OG, The sentence above, choice (A), is correct. OG says, "they" refers to property values. Why is there not an ambiguity here with large investors?
Take this for example -
While depressed property values can hurt some large investors, they can always mitigate their losses by timing the market.
Sorry, I am totally confused and stumped with pronoun reference when two potential antecedents are both plural - there is no good explanation anywhere.
