<p>On the Wednesday PSAT, there was a question very similar to the following:</p>
<p>Though the laureate has written numerous poems, articles, and books, it is her plays that are the most famous.</p>
<p>A) it is
?) they are</p>
<p>I personally chose "they are," but later reasoned that it should probably be A since "it" might be acting as a dummy pronoun. Does someone have their test booklet, or is there a grammarian out there? The answer to this question is unresolved.</p>
<p>Ok I’m not 100% sure. Just want to make that clear so please correct me if I’m wrong. This is how I’d solve this.</p>
<hr>
<p>It’s A)</p>
<p>Replace <it is=""> with <they are=""> and you get…</they></it></p>
<p>(simplified down a lot)</p>
<p>Although bob wrote books and articles, they are her plays that are most famous.</p>
<p>Now replace <they are=""> with what it’s supposedly referring to…</they></p>
<p>Although bob wrote books and article, her plays are her plays that are most famous. </p>
<p>You can even transfer reasoning to a different sentence…</p>
<p>Although she has physical strength, vision, and height, her dribbling skills her dribbling skills that make her good at basketball</p>
<p>Let’s put “it is” in that sentence.</p>
<p>Although she has physical strength, vision, and a tall stature, it is her dribbling skills that make her good at basketball. </p>
<p><it> is acting as a dummy pronoun.</it></p>
<p>I think you must be right.</p>
