<p>@all of you guys, thank you so much for investing so much of your time and effort into this;</p>
<p>well, @realityisadream, SirWanksalot,
I learned that the antecedent of a relative pronoun like “who” is usually the noun that is the closest to it. So, if I apply this principle:</p>
<p>Jason (is) the only one of the three people I (knew well) in middle school who still (write) to (me regularly). (No error)</p>
<p>The antecendent of “who” would be “the only one of the three people” since “of the three people” is an adverbial phrase for “one.” Correct?</p>
<p>Okay, my second question is with the very similar example sentence that I have provided:</p>
<p>I will catch one of the five girls who bullies/bully in class.</p>
<p>The same logic that I have applied with the above sentence tells me that “of the five girls” is the same adverbial phrase as “of the three people.” Thus, I feel that “one” is the antecedent and that “bullies” is correct. Can you explain this further? It just sounds like faltering logic to me to change the answer in this case. :)</p>
