<p>After viewing the presentation given by the county fire marshal, each of those attending the meeting decided they would be a volunteer firefighter. </p>
<p>Read this before you reply:</p>
<p>*The underlined portion of the sentence is ''they would be a firefighter''.</p>
<p>Choices:</p>
<p>a) they would be a firefighter (I've eliminated this already.)
b) they will become volunteer firefighters
c) to become volunteer firefighters
d) to become a volunteer firefighter
e) to become volunteer firefighters</p>
<p>Why is the correct choice D? I omitted this question. Thanks.</p>
