<p>ok, i think these are all classified as "hard" by the collegeboard themselves.</p>
<p>first is number 11.
why the heck is it E. i thought you would need something such as but or although, but it goes straight to and!!</p>
<p>next is number 27
"Mastery of cardiopulmonary resucitiation tecniques are..."
it said are is wrong, tecniquess? = are? no? and i dont think u can use mastery as the subject...</p>
<p>Number 28
I have no idea why this one is D</p>
<p>"use of plastics is greater than steel, aluminum, and copper combined"</p>
<p>why is "than steel" wrong</p>
<p>Finally number 29
the wierdest sentence i have never since, i will write the whole thing out for this one</p>
<p>The dolls in the collection, all more than two hundred years old, had been carefully carved for children long since gone.</p>
<p>......how is that E, no error lol. the last part dosen't make sense</p>
<h1>27 - Mastery can indeed be the subject; in fact, it has to be because the object of a prepositional phrase (techniques) can never be the subject.</h1>
<h1>28 - You must compare like things - you need to compare “use of plastics” to “use of steel.”</h1>
<h1>29 - The phraseology is a bit archaic, but it is grammatically correct. Gone is an adjective modifying children, and long since is an adverb modifying gone.</h1>
<p>Readers of the novice writer’s recent book have said that it is at once frustrating because of its chaotic structure but it’s originality i still a delight</p>
<p>“but its originality i still a delight”
should be changed to
“and delightful because of its originality.”</p>
<p>The main issue in this one isn’t whether you use and or or - the lack of parallelism in the original is a much bigger issue. Whenever you have a series of items, they all need to be in the same form. In the original sentence, frustrating is an adjective but originality is a noun. The correct answer fixes that and makes them both adjectives.</p>
