<p>This is an answer choice from the question:</p>
<p>The light-year is the distance traversed by light in one year, and sometimes astronomers use it when interstellar distances are described. </p>
<p>Is there any sort of error in that sentence? If so, please explain!</p>
<p>Another question I have: Is it true that the questions from the review sections of SAT books are easier than the ones in practice tests? (I haven’t really begun the practice tests yet because I still have the essay and math section left to do. I’m taking the Nov. SAT)</p>
