<p>1.Before, the Chomskyan revolution in linguistics, (it was widely assumed that babies learn) all aspects of language from those around them.</p>
<p>this sentence contains no error; however, what does the it refers to? i always think that 'it' on the sat as a pronoun almost certainly contains a error because of its ambiguity.</p>
<p>2.i was in Ethiopia on a field (expedition, i was camped on) the edge of a small muddy river,</p>
<p>(a)expedition, a camp on------------- this is the answer i chose.
(D)expedition, camped on----------- correct answer.</p>
<p>both answers seem right to me. a nonessential clause and a participle phrase.</p>
<p>one more:
Since nearly all those accused in the 1692 Salem witch trials were women, to discuss the trials without considering issues of gender (is neglecting an aspect of the events that is important.)</p>
<p>(B) is neglecting an important aspect of these events------i chose this answer
(C) is to neglect an important aspect of the events------right answer</p>
<p>not sure the grammar error in this sentence.</p>
<p>“I was in Ethiopia on a field expedition, a camp on the edge of a small muddy river,”</p>
<p>is incorrect.</p>
<p>The usage implied by the structure “field expedition, a camp” is that of an appositive, a very common English language structure. In brief an appositive is a noun, noun phrase, or series of nouns placed next to another noun or noun phrase to identify it, or rename it, or clarify it.</p>
<p>“a camp” is something quite different from a “field expedition”. The appositive usage pattern is illogical.</p>
<p>A noun phrase that would make sense with the sentence at hand is:</p>
<p>“I was in Ethiopia on a field expedition, a trip sponsored by the United Nations,”</p>
<p>Since nearly all those accused in the 1692 Salem witch trials were women, to discuss the trials without considering issues of gender is neglecting an aspect of the events that is important.</p>
<p>is incorrect.</p>
<p>The lack of parallel structure is the issue, specifically the necessary parallelism is:</p>
<p>to discuss <something> is to neglect <something></something></something></p>
<p>You can fix this sentence in another way (although this is not one of the choices) – i.e.</p>
<p>Since nearly all those accused in the 1692 Salem witch trials were women, discussing the trials without considering issues of gender is neglecting an aspect of the events that is important.</p>
