Help with these BB questions plz!

<p>These questions are from pg 602 in the BB. I ask of you to please explain why the correct answer is correct and possibly why my answer was wrong. (All the correct answers are in bold.)</p>

<ol>
<li>Because they painted scenes of life as ordinary people lived it, rather than scenes from myths, many nineteenth-century American artists differed from earlier times.</li>
</ol>

<p>(A) Because they
(B) lived it
(C) rather than
<a href="D">b</a> from earlier times<a href="E">/b</a> No error</p>

<ol>
<li>The young fish were very tiny, yet each of them ate many times its own weight in solid food everyday.</li>
</ol>

<p>(a) were
(b) them ate
(c) its
(d) weight in
<a href="e">b</a> No error**
For this one, I thought the answer was C. The earlier part of the sentence states "them" so I would think "their" would belong in the place of "its."</p>

<ol>
<li>Driving less frequently is one way to save energy; to turn off all appliances when they are not being used is another.</li>
</ol>

<p>(a) less
<a href="b">b</a> to turn off<a href="c">/b</a> when they are
(d) is another
(e) No error
I think this one has an error in parallelism if I am correct. It should be "Turning off."</p>

<ol>
<li>After Gertrude Ederle had swam the English Channel, she was celebrated as the first woman ever to accomplish the feat.</li>
</ol>

<p><a href="a">b</a> had swam<a href="b">/b</a> was celebrated as
(c) to accomplish
(d) the feat
(e) No error
I initially thought the error was in D. I thought "the feat" was supposed to be replace with "this feat."</p>

<p>I know this is a long post but please help me!</p>

<p>it has to be D “those from earlier times”</p>

<p>without “those”, ur comparing people to a time period</p>

<ol>
<li><p>The pronoun must agree with the subject, not the object of the prepositional phrase. Each and its are both singular.</p></li>
<li><p>You are correct.</p></li>
<li><p>The correct form is “had swum.” As for D, either works.</p></li>
</ol>

<ol>
<li><p>“from earlier times” should be “from artists of earlier times.” The 19th century artists are being compared to other artists, not “earlier times.”</p></li>
<li><p>“each of them ate many times its own weight.” Now ignore the prepositional phrase: “each ate many times its own weight.” Make more sense? Each is singular, so the pronoun (its) must be singular as well.</p></li>
<li><p>You are correct, it is an error in parallelism</p></li>
<li><p>The past perfect tense is being used here. The correct past perfect tense of to swim is “had swum.” “Swam” is the correct** past** tense of to swim.</p></li>
</ol>

<p>Ok, thanks guys. I still have a bit of confusion with 19 though. What’s the difference between past perfect tense and past tense? When do you know which one is being used or is supposed to be used?</p>

<p>Essentially, past tense occurs before something in the present, and past perfect occurs before something in the past.</p>
