<p>In the REAL ACT PREP GUIDE, on test 4 there was a science question that I found extremely odd and incongruous with usual ACT science questions. It went something like,</p>
<p>"For any of the rods described in the passage, most heat is transferred between the ends of the rod by which of the following processes?"</p>
<pre><code> I. Radiation
II. Convection
III. Conduction
</code></pre>
<p>Nowhere in the intro did it mention any of those words. In the answer explanation in the back, it just said that heat is transferred by conduction in metal rods. I had no idea what any of those words meant offhand, though. I thought the ACT didn't test you on your background science knowledge? Is this something they consider common knowledge?</p>
