<p>The Question: He interviewed several candidates who he thought had the experience and qualifications he required.</p>
<p>The correct answer for this question was to substitute the underlined by using "who he thought"</p>
<p>I am really confused by this. </p>
<p>Isnt the person the "who" is referring to the candidates? and isnt Candidates the object of the sentence (since "he" is doing the action)?</p>
<p>I thought object=whom</p>
<p>The explanation at the back of the book says the following: Choice A is correct because the subject of the verb "had" must be "who," not whom.</p>
<p>Can someone explain..</p>
