<p>question 17, Paule Marshall, whose Barbadian background has influenced her writing, describes many details of life in the Caribbean islands vividly in her novels and short stores. no error. why no error? I chose B has influenced.
question 13 same page. and page 480 question 28. I chose no error.
Thank you all. I am waiting for the explaination</p>
<p>Why did you think “has influenced” was wrong? Without knowing that, all I can say is that there’s nothing wrong with it. The past tense is fine, and it’s singular to go with “backround.”</p>
<p>For #28, “its” is referring back to “tablets,” so it should be plural to agree with the plural noun. “Their” would work.</p>
<p>Okay chelseaSAT, I suggest you post the questions with your thread next time because not everyone has his BB beside the computer.</p>
<p>anyway, explanations:</p>
<ol>
<li>the sentence can be broken into two discrete sentences:
Paul Marshal describes many details of life in the Carribean islands vividly in her novels and short stories.
Paul Marshal’s Barbadian background has influenced her writing.</li>
</ol>
<p>You see there’s an overlapping word “Paul Marshal”? so we use possessive form of “who”, which is, “whose.”</p>
<p>So the sentence is essentially correct; choice B, “has influenced,” is not an error because it matches with singular subject, that is, Barbadian background.</p>
<ol>
<li>the sentence has parallel structure; you should recognize the form. The contract will “satisfy” the demands and (will) “be” acceptable to ~~~.</li>
</ol>
<p>note that “will” is omitted from the latter one, and infinitives (satisfy and be) are used in both cases. So the sentence contains no error.</p>
<ol>
<li>the pronoun “its” refers to “multivitamin tablets,” so singular form should not be used. “their” will fit well into the sentence.</li>
</ol>
<p>So why is the sentence in #13 on pg 479 still parallel even though there’s not “will” after “be acceptable to”? I put D because I thought that in order for the sentence to be parallel you need to saay “will be accetable to”</p>
<p>good question, now i think about this… no idea</p>
<p>Helping verbs don’t have to be put in front of both verbs; it’s understood that it’s applying to both.</p>
