<p>Even when Barbara Jordan put questions [toward] a political nominee, her elegant diction evoked in listeners memories of her eloquent political speeches.</p>
<p>Why is "toward" incorrect? What should it be changed to?</p>
<p>toward implies actual motion:</p>
<p>I am driving toward Maine.</p>
<p>to doesn’t imply direction:</p>
<p>I am giving this apple to you.</p>
<p>In this case we need to.</p>
<p>If you want to get really technical, political nominees is the indirect object, so it requires “to.”</p>
