<li> Traffic was so heavy, so by the time Brianne finally (arrived at) the theater, we (waited) for her for an hour, (missing) the (entire) first act of the play. </li>
</ol>
<p>the wrong answer is (arrived at). i initially picked that answer, because i thought it should have said "had arrived at" but then missing seemed wrong as well, so i choose missing instead. can someone please explain? thanks! </p>

<li>(Squandering) his inheritance, the prodigal (felt no) (regret about) wasting his (fathers) hard-earned fortune.</li>
</ol>
<p>the answer is no error, but i thought "felt no" was wrong because everything else seemed to be in the present tense? why is it okay to have past tense "felt no" and then to have "squandering" (which is present?) as well? thanks!</p>
<p>“missing” is fine because it clearly modifies “we” as a participle.</p>
<p>“waited” occured before the past action of Brianne’s arrival, so it needs to be the past perfect: “had waited.” I’m not sure where you got (A) as the correct answer.</p>
<p>“felt” is the only verb in the sentence, so the past tense is fine.</p>
<p>“squandering” is an adjective (specifically, a participle) there; it’s not the present progressive, which is also “squandering.” We know this because it’s in a participial phrase succeeded by a comma.</p>
