<p>why B? </p>
<p>btw, is it just me or is the BB harder than PR in critical reading?</p>
<p>and also, PG 525 #8...</p>
<p>PR sucks my friend. The Blue Book's as accurate as you can get with practice tests for the SAT, besides the QASes.</p>
<p>lol. that's like the first time i heard someone say that PR sucks. </p>
<p>anway....can anyone explain those questions??</p>
<p>Well... the author describes the first mechinal clocks as in "crisp, regular intervals" and that it would have surprised people if it was in "their own mental and physiological processes" </p>
<p>So when they have their 'own' processes, etc., then the statement that would weaken the author's argument is "discrete, uniform intervals"</p>
<p>It is sort of confusing.</p>
<p>i still don't quite get it....what about the second question also? anyone</p>
