<p>Many people think taxes are too high; consequently, some do not report all the money they earn. </p>
<p>How is this correct? Isn’t “some” unclear? I thought you would have to put more detail after “some.”</p>
<p>It seems that there are two contributing factors:
[ul]
[<em>]The referrent of the pronoun “some” is the subject of the previous clause, which makes it more grammatically acceptable.
[</em>]“some” can, by itself, mean “people” even if there is no referrent of “people.”[/ul]</p>
<p>What do you mean it is unclear? The subject of the first clause is “many people.” The subject of the second clause is “some [people].” “People” does not have to be repeated because it is replaced by the pronoun “some.”</p>
<p>In other words, it is implied. There is no reason to think “some” refers to “taxes” or otherwise. </p>
<p>Other examples of indefinite pronouns are: one, each, either, neither, some, any, one, all, both, few, several, many, most.</p>

<p>I believe he was approaching it with the (in this case, overly) discerning eye of an SAT preparer.</p>
