<p>In the north pole, the ground is riddled with ice wedges, many quite old, caused by the cold earth cracks and the cracks fill with water.
A. by the cold earth cracks
B. by the cold earth cracking
C. When the cold earth cracks
D. where they crack the cold earth
E. through the cold earth cracking</p>
<p>wats the diff between A and C, whats make one of them wrong, n correct?</p>
<p>C</p>
<p>Ask you self, what is causing the ice wedges? How? the "cracks fill with water" is the reason for the wedges. Its WHEN the cracks fill with water that leads to the ice wedges. its not caused BY the cold earth cracks, but WHEN the earth cracks and then the cracks fill with water. Somewhat a dangling modifier, plus theres a bit of logic involved.</p>
<p>Hope that helps bro</p>
<p>C.
because the entire phrase after 'caused' gives the cause.</p>
<p>ugh. thx. logic sucks especially when it comes to weird things that i've never heard before.
in this case,i didn't understand what the sentence is saying T_T
this is a big prob lol</p>
<p>This is way familiar. BB or May QAS?</p>
<p>may, but i rephrased it to avoid trouble =]</p>
