<p>A poetic form congenial to Robert Browning was the dramatic ..... a character's mind without the simplifications demanded by stage production
{I was wavering between these two choices}
(B) monologue, which let him explore
(C) monologue that lets him explore</p>
<p>:Why is B correct. isnt the subject singular (poetic form) ??</p>
<p>let is past tense. (Who let the dogs out/ who lets the dogs out)</p>
<p>and the answer isn’t C because the second phrase is subordinate to the first.</p>
<p>Also, as another justification to rule out answer choice C, when you use the word “that”, a restrictive clause, you are defining its antecedent. In this case, the antecedent would be “dramatic monologue” , but you’re not really defining it, meaning that you’re not really mentioning anything that would seperate this dramatic monologue from other dramatic monologues.</p>
