<p>there is a curve</p>
<p>science usually has a really hard curve though doesn't it?</p>
<p>lukeli88:
i was done with english like 20 minutes early and i spent the rest of that time scrutinizing that question lol. ultimately i chose "an author.. an author's" or whatever (not each). something which was singular in the previous sentence lead me to believe so.</p>
<p>and about the test in general:
i thought science was sooo much harder than before. last time i got a 35 on the science section (April 2006). this time... ehh DEFINITELY NOT!</p>
<p>I spent a long time on that question too. I think I finally went with "each author's". It was probably wrong.</p>
