<p>Could anybody explain why these answers are right?</p>
<p>(the parts in parenthesis are wrong)</p>
<li><p>The department of transportation has introduced pictorial traffic signs because drivers can react to (this) more quickly than to verbal ones.</p></li>
<li><p>She claimed that the “representational” actor (is having to imitate) a character’s behavior, whereas the “presentational” actor attempts to reveal human behavior through self-understanding.</p></li>
<li><p>Far (away from) having been a diehard conservative, Hoover was, some scholars now contend, the leading progressive of his day.</p></li>
</ol>
<p>thanks!</p>
