<p>section 3 number 9
why can't the answer be D (answer is c)</p>

<p>secion 3 number 25
what's the error (answer is B)</p>

<p>section 3 number 27
what's the error? (is it verb tense?) (answer is D)</p>

<p>THANKS!!!</p>

<h1>9:</h1>

<p>If "since" is used, you don't need a semi-colon. A semi-colon to join two stand-alone sentences. By adding "since," you join the two sentences with a conjunction.</p>

<h1>25:</h1>

<p>Wrong idiom. The correct usage is "to change" not "of changing"</p>

<h1>27:</h1>

<p>"To be" is the wrong verb tense. "To be" is in the infinitive form whereas the correct answer is "as," which is in the present tense.</p>

<p>thankkkkkkkkkkkkkkkk you</p>
