<p>Just got QaS and have a couple of questions</p>
<p>Just by unplugging your cell phone charger when you are not using it reduces carbon dioxide pollution.</p>
<p>C: just unplugging your
D: by just unplugging your</p>
<p>Why is the by not needed and where would it have been needed?</p>
<p>25: The habitat in which sequoia trees grow, extends from southern Oregon to northern California, is kept damp year-round by heavy seasonal rains, cool coastal air, and fog.
-wth is wrong with extends? doesn't that properly agree with habitat?</p>
<p>29: In The Big Sea, Langston Hughes recounts his childhood and early adulthood in language that is as simple and direct as another Missouri-born writer, one much admired by Hughes, Mark Twain.</p>
<p>Would the correct one be "as that of another" . i knew something was up when language was compared to another writer, but I just want to know how to fix this?</p>
<p>23: Though i am acquainted with Mr. Bartholomew and have long known of his interest in the painting, that he has gone to such lengths to obtain it astonishes me.</p>
<p>the present tense for astonish works ? really? O.o</p>
<p>“25: The habitat in which sequoia trees grow, extends from southern Oregon to northern California, is kept damp year-round by heavy seasonal rains, cool coastal air, and fog.
-wth is wrong with extends? doesn’t that properly agree with habitat?”</p>
<p>“nvmd i guess for 25 it’s supposed to extended… to match up with kept.”</p>
<p>No, the habitat continues to extend as described in the sentence, so the present tense is correct. The mistake is that, given the comma placement, “extends from southern Oregon to northern California” needs to be a participial phrase. So the sentence would be:</p>
<p>“The habitat in which sequoia trees grow, extending from southern Oregon to northern California, is kept damp year-round by heavy seasonal rains, cool coastal air, and fog.”</p>
<p>"29: In The Big Sea, Langston Hughes recounts his childhood and early adulthood in language that is as simple and direct as another Missouri-born writer, one much admired by Hughes, Mark Twain.</p>

<p>"Though i am acquainted with Mr. Bartholomew and have long known of his interest in the painting, that he has gone to such lengths to obtain it astonishes me.</p>
<p>the present tense for astonish works ? really? O.o"</p>
<p>For the last question, I am pretty sure that either astonishes or astonished would have worked since the time isn’t clearly addressed.This means that it is not an error since it can work.</p>
