<p>Which is right, ones or twos (or neither)?</p>
<ol>
<li>You’re right Eugene, I do do that.</li>
<li>While even though Caroline had had many thoughts on the issue, she was quiet.</li>
<li>I didn’t know that that man over there was a deranged maniac.</li>
</ol>
<p>They’re all right with respect to what you’re asking. </p>
<ol>
<li> The sentence uses the emphatic tense paired with the verb “to do.”</li>
<li>“While even though” is improper, but “had had” is fine; it pairs the past participle of “to have” with the auxiliary verb for the past perfect tense: “had.”</li>
<li>The sentence correctly pairs a relative pronoun with a demonstrative pronoun.</li>
</ol>
<p>lol, i screwed up, sorry.</p>
<p>just are those sentences grammatically correct?</p>
