Dear Ron
I came across this question from OG13 - SC - #93. I understand that "those" should not be the focus of this question, as all the five choices have "those". But I am curious to learn from you whether "those" have to have an antecedent. Clearly, in this sentence, "those" cannot refer to "nobody", so "those" have no antecedent in this sentence.
Thank you
Michael
