<p>So for the critical reading about the mathematician and his caretaker, what was the significance of him giving a half an hour lecture to explain negative numbers? I thought this one was easy, but now I’m not so sure if I got it right.</p>
<p>That was probably experimental, as I did not have that section.</p>
<p>Yeah, I didn’t have that one either.</p>
<p>I had that! But I can’t remember the answer. Too bad it was experimental 
I did well on that one</p>
<p>It is REAL. As far as I know, there are 2 diff versions of real tests. I had math experimental so I know I had all real reading sections ( had 3 so im right)</p>
<p>It wasn’t experimental; there were two different tests. </p>
<p>For that question I put something along the lines of “removing a skepticism”, because the purpose of the lecture was to remove the doubt of having negative numbers.</p>
