<p>7.(Whether the ancient Egyptians actually sailed or did not) to S. A. remains uncertain, but Haps expedition demonstrated that they could have done so.</p>
<p>Answer is "That the ancient Egyptians actually sailed". Why?!</p>
<p>9.Isolated by the sea, the aboriginal peoples of Australia (had developed a unique culture) long before the arrival of Europeans.</p>
<p>Answer is As is. Why does this sentence require a singular verb? is it because the subject is aboriginal?</p>
<ol>
<li>Few issues of public policy (are ) as (likely) to provoke widespread interest as (that) involving possible (danger to) the health or safety of children.</li>
</ol>
<p>Answer is that.... why? is it because it should be those? and few automatically means plural right?</p>
<ol>
<li>The exchange between the teacher and the student (promotes) learning (far different) from that which results (as) the student listens (but does not ) participate.
I thought it was B since it should be far differently but the correct answer is C...WHY!?</li>
</ol>
<ol>
<li><p>Because it is the most direct grammatically correct way to express the idea. ‘Or not’ or ‘or did not’ are implied in ‘whether’ and are, therefore, redundant.</p></li>
<li><p>The subject is ‘peoples’. ‘Aboriginal’ is an adjective. The verb ‘had developed’ is both singular and plural. He had developed a method before some other event occurred…They had developed a method before some other event occurred.</p></li>
<li><p>You got it.</p></li>
<li><p>The comparison is between two kinds of learning. The word ‘different’ describes the noun ‘learning’, not the verb ‘promotes’. ‘Different’ is an adjective. ‘Differently’ is an adverb. I would have used ‘when’ rather than ‘as’, but the Oxford American Dictionary shows them to be synonyms, and I haven’t found any rules that bear on the question.</p></li>
</ol>
<p>A correction for 15. ‘Few’ is used as an adjective modifying ‘issues’, which is the subject. Otherwise you got it.</p>
<p>Well i was just asking in general about few… lets say if we have a setence “few are crowned champions”. few always requires a plural subject correct?</p>
<p>‘Few’ in your example is used as a pronoun. Its referent is often understood to be something like ‘people’. In any case, when it is used as you used it, it is plural.</p>
