plz. help me with these hard writing question.

<ol>
<li><p>one of the (good things about) using corn oil as automobile fuel (is)(that) it makes car exhaust(smell) appealingly like French fries (no error).</p></li>
<li><p>Many environmentalists think (that it is) just as important (to use) existing energy sources efficiently (than) it is to develop pollution-free means (of generating) energy. (No error)</p></li>
</ol>

<p>IS IT RIGHT THAT THE OBJECT TAKES THE VERB IN THE INFENTIVE FORM? </p>

<p>thnx in advance. :D</p>

<p>Do you have a particular question about (1)? It appears to be correct – i.e. no error.</p>

<p>(2) Has a faulty comparison. Replace ‘than’ with ‘as’. ‘than’ is used to suggest that one notion/quantity is greater/better than another. ‘as’ is used to suggest equality.</p>

<p>thnx very much FOGCITY, in question,1) iI thought that car exhaust must take ‘‘smells’’ . and I was asking that ''can the object takes the verb in infentive form. </p>

<p>2) our teachers told us that “just as” must take “so”.
sorry , but I am an international student and our teachers are not understanding anything they are telling us myth. :P</p>

<p>In problem 1 the clause “it makes car exhaust smell” is special in that “makes” functions as a “causative verb” – the subject “it” causes the object “car exhaust” to do something “smell”. The form of the verb “smell” is the base form – that for all persons (gender and plurality). Google “causative verb” to find additional examples.</p>

<p>In problem 2 we do NOT have the coordinating conjunction pair “just as” … “so”. Rather the operative idiom is “as important as”. “just” functions as a simple adverb.</p>

<p>Thank you very much,I am sorry if bother you. :D</p>

<p>can any body help me with this question with the correction plz ?? a human runner amazed the world in 2004 (by winning) the man versus horse marathon ,(it) has pitted hundreds of people (against) horses every (year since) 1980. (no error)</p>

<p>THNX FOR YOUR EFFORT. :)</p>
