<p>Above the beautiful white-sand beach runs two rivers that eventually combine to form a waterfall cascading to the sand.
a) runs
b) eventually
c) to form
d) cascading
e) no error</p>

<p>answer: a</p>

<p>The thing, which extends down the eastern coast of Candyland, has many hidden caves, one of which is larger than the size of this water bottle.
a) extends down
b) has many hidden
c) of which
d) than the size of
e) no error</p>

<p>answer: d</p>

<p>Excuse my weird wording for the 2nd one-it was just for fun (and was shorter to type).
Can someone explain to my why...I still don't understand why those two are.</p>

<p>For the first one, we are talking about the two rivers. Take it this way:</p>

<p>Above----------runs [?] two rivers ?</p>

<p>Rivers is plural hence it should be run.</p>

<p>I am not really sure about the second one.</p>

<p>the second one should be "this water bottle (is)" rather than "the size of this water bottle"...because you're comparing the water bottle to caves, not the sizes of caves</p>

<p>Thanks so much... it seems so simple now, but somehow, I always end up overseeing the errors.</p>

<p>subject verb agreement</p>

<p>improper comparison</p>

<p>haha anytime!</p>

<p>omg Penser thanks SO MUCH! YOU ARE GENIUS</p>
