Confused by Writing Question...?

<p>"The acoustics of the ancient Greek theater at</p>

<p>Epidaurus are <so good="" that=""> an actor's words,</so></p>

<p><even when="" whispered="">, are <auditory> to <those sitting=""> </those></auditory></even></p>

<p>in the last row."</p>

<p>Although I got a 780(Lucky I guess) on the SAT writing in March, I just can't figure out why <auditory> is the error in this sentence.... I'd appreciate if anyone can explain the answer.</auditory></p>

<p>Thanks in advance!</p>

<p>Instead of “auditory,” it should be audible.</p>

<p>Wow that didn’t even cross my mind. Thanks, I get it now! :)</p>

<p>No problem! Feel free to post all your writing questions here lol</p>
