<p>In dating unkown works of art, scholars becomep detectives, following down clues and working out theories that fit the available facts. No error</p>
<p>What should be there instead of “following down”?</p>
<p>“Tracking down” is the correct idiom. “Following” would also work, as would a number of other words.</p>
<p>Another one
PIctures of vipers drawn on the walls of caves suggest that preistoric hunters may have used snake charms for bringing good luck. No error</p>
<p>I chose “for bringing” because it sounds wrong in the sentence and I was correct. But why is it wrong?</p>
<p>@Godfatherbob
Thanks! But does “follow down” actually mean anything?</p>
<p>
</p>
<p>No. It’s like saying “how’s up” instead of “what’s up”</p>
<p>
</p>
<p>It’s a prepositional error. You don’t use things for bringing, you use things to bring.</p>
<p>Thanks a lot!!</p>
<p>i didn’t get the following part =/ , ouch tracking and following T_T
i thought the second one was quite obvious and easy though.</p>
