<p>A poetic form congenial to Robert Browning was the dramatic [monologue, it let him]explore a characters mind without the simplifications demanded by stage productions.</p>
<p>(B) monologue, which let him explore
(C) monologue that lets him explore</p>
<p>the answer is B and I know why C is wrong
but the thing is I don't understand why "let" is in the past tense, and "lets" is in the present tense. Isn't "lets" singular??
HELP! THANKS!</p>
<p>But clearly the action occurred in the past. Browning wrote in the 19th century.</p>
<p>The clause “Which … him explore” must reference the past tense.</p>
<p>Also consider that “which” and “that” have different inferences – one begins a non-restrictive clause and the other a restrictive clause. “which” is the more accurate form in the question.</p>
<p>I understand why it must be past tense
but i don’t understand why “let” is past tense, and “lets” is present…
can you explain on that ? thank you</p>
<p>Is it because “let” is a irregular verb?</p>
<p>It is irregular. See:</p>

<p>Okay… I think I kind of get it now.
Thank you!</p>
