<li>“(Nearly all) of the photographers for the project (agree) that of the two prints (being considered), Morton’s is the (more appropriate)”</li>
</ol>
<p>why is there ‘no error’ ?</p>
<ol>
<li>The new mechanism, which (uses) automated sensors (in the controlling of) the entire assembly line, (should improve) the efficiency of the entire operation.</li>
</ol>
Nearly all is fine
agree is fine as well (all photographers agree)
being considered, nothing wrong with that
more appropriate is fine ( comparing 2 things)</p>

<li>I think ‘in the controlling of’ sounds passive and could be avoided by substituting in “to control”?</li>

<p>Citing increasing labor costs, the reluctance of many people to fly, and unseasonably cool weather, tourism analysts have been cautious not to expect a great season.</p>
<p>I think the error is D. It should say …tourist analysts have been cautious to expect a great season.</p>
<p>i just dont get the original sentence, isnt " increasing labor costs" good for tourism? doesnt this phrase mean that workers are gaining more money than before?</p>
<p>This is more of an economics question but yes, because travel agencies have to pay their workers more, their production costs rise and therefore must compensate by, among other ways, raising prices–an action that most probably will repel would have been customers who do not value the travel more than the listed price.</p>
<p>That’s an oversimplified analysis and is in any case irrelevant to the SAT.</p>
<p>
Not it itself. Because of plummeting prices, consumers have been cautious not to let their friends pass up on value deals unknowingly.</p>
<p>The word “not” is a weak but grammatical word for negation–most phrases with not can be replaced with a combination of the elimination of not and the replacement of the word not had modified with an antonym (e.g., not pass with fail, not too long with short). In the sentence from the SATs, cautious not to can be replaced with reluctant to…</p>
<p>and in the controlling of is not ungrammatical but is probably wrong because the SAT considers the phrase verbose. Controlling is also a useless gerund because control is a better noun meaning the same thing, so “under the control” (still a prepositional phrase but fails to fix the unavoidable passive construction) is a suitable substitute.</p>
