<p>F. The students want to become a doctor rule</p>
<p>In a file that I’m studying. What is this rule? I don’t know it, and I can’t seem to google information about it - help please?</p>
<p>I’m assuming the use of "rule’ is slang. In that case the answer should be “The students who want to become doctors rule”.</p>
<p>It’s basic subject-verb agreement.</p>
