<li>Surface mining is safer, quicker, and cheaper than deep mining, but the (greater is its toll in human misery) -brackets equal underlined portion.</li>
</ol>
<p>A. the greater is its toll in human misery
B. It has a greater human misery toll
C. in its human misery toll is greater
D. there is the greater toll in human misery
E. its toll in human misery is greater</p>
<p>The answer is E…why can’t it be B?</p>
<li>Conflicts between land developers and conservationists have repeatedly arose.</li>
</ol>
<p>arose is wrong in that sentence, is it supposed to be risen? and why?</p>
<li>Air pollution caused by industrial fumes (has been studied for years A), (but B) only recently (has C) the harmful effects of noise pollution (become D) known.</li>
</ol>
<p>why is the answer C?
sorry, will really appreciate any help</p>
<ol>
<li>Not sure, but E doesn’t sound nearly as awkward as the rest of the choices.</li>
<li>rise, rose, has/have risen–kinda like sing, sang, has/have sung</li>
<li>“Has” should be “have” because the subject it is modifying (harmful effects) is plural.</li>
</ol>
<ol>
<li>Not only does choice B have a capitalized first letter, but when you insert the answer choice, it goes: Surface mining is safer, quicker, and cheaper than deep mining, but the It has a greater human misery toll.</li>
</ol>
<ol>
<li><p>b isn’t a good choice because ‘has’ isn’t quite appropriate. it has a toll? has is sort of a possessive word (“the cat has a cheeseburger”). So surface mining doesn’t really have a toll. It causes one, maybe. Surface mining can have benefits, it can have appeal, etc…but have a toll? nope.</p></li>
<li><p>when you use the past perfect as in “have arisen” the word form is different. If you want to say “conflicts repeatedly arose”, that’d be okay, just a different tense.</p></li>
<li><p>do a little re-arranging to see what sounds right. “the harmful effects has been known”? The effects? <em>Has</em> been known? No, the effects <em>have</em> been known. if you wanna get technical has is singular and have is plural. The cats have cheeseburgers.</p></li>

<li>Conflicts between land developers and conservationists have repeatedly arose.
Arisen, because the tense is present perfect, which follows the form:
subject + have + past participle
So the past participle of arise is arisen.</li>
