<p>Most of the hypotheses that Kepler developed to explain physical forces were later rejected as inconsistent to Newtonian theory. No error.</p>
<p>--- The answer is D. Why isn't it No error (E)?</p>
<p>The cost of safely disposing of the toxic chemicals is approximately five times what the company paid to purchase it. No error.</p>
<p>--- The answer is D. While I understand that D is incorrect, isn't A incorrect as well? Shouldn't it be "the cost of the safely disposing" or "the cost of safely disposing the toxic chemicals"?</p>
<p>1st one.</p>
<p>The idiom is inconsistent with. You just have to know that one</p>
<p>2nd one.</p>
<p>While A may sound extremely absurd, it is actually grammatically correct. I do not know why you would you say it should be "the cost of the safely disposing".</p>
<p>Moreover, there is no possible rule that that error you suggest could fall under (review your categories). If there is no rule, there is no error.</p>
<p>It should be 'inconsistent with,' as in "A legal analysis by the nonpartisan Congressional Research Service concludes that the Bush administration's limited briefings for Congress on the National Security Agency's domestic eavesdropping without warrants are 'inconsistent with the law.'"</p>
<p>To dispose is to put people or things into a particular order or place, as in a commander who disposed his forces along the coast.
To dispose of is to get rid of something, so it is correct to say "The cost of safely disposing of the toxic chemicals."</p>
<p>Also, D is a pretty clear error; "to purchase it". "It" is a singular pronoun, but it refers to a plural noun, "chemicals", so that is obviously incorrect.</p>
<p>Always go for the one that you know is incorrect :)</p>
<p>Oh, of course, consistent with. I couldn't think of what was wrong.</p>
<p>And I don't know what the categories you are talking about are. Could you please explain?</p>
<p>dchow08: thanks for the explanation! i completely understand now :D</p>
<p>zoaxanthellae: ok, thanks for the tip. i guess i usually just stop reading the sentence when i find an error, because usually i'm correct.</p>
