<p>A To understand twentieth-century economic practices, B we must be sufficiently C familiar with Keynesian theories, whether one agrees D with them or not. E No error </p>
<p>I know that B is wrong, but wouldn't D be an ambiguous pronoun problem? The "them" can refer to both "practices" and "theories", right?</p>
<p>No. “One must be sufficiently familiar with Keynesian theories” is the main clause, so the elements of the subsequent clause refer to it. “One” is a pronoun, so it is simply repeated. “Them” substitutes “Keynesian theories.”</p>
<p>^ i think she’s saying that the answer choice could also be D even though the better answer choice B because “them” could refer to theories or practices.</p>
<p>^</p>
<p>What…?</p>
<p>^^ he. :|</p>
<p>Rephrase of question: </p>
<p>B is wrong. I know that. Is D correct though? Why? Isn’t there an ambiguous pronoun?</p>
<p>I’m pretty sure it’s not because clearly, there can only be one error in the sentence. so in that case, ill go with crazybandit that the main clause is “we must be sufficiently C familiar with Keynesian theories.” “them” is clearly referring to keynesian theories.</p>
