I downloaded the 1000 CR, and was trying test 12. The answer keys at the end of the document are different from the hiddent text that specify the answer against the options, esp questions no 8,9,10,13,15,18 I havent gone through the rest.
Now which is the right answer.Can anyone pls help.

I chose the following for the above questions, Can anyone pls tell me if they are right.
8 - C
9 - A
10 - C
13 -C
15 -B
18 - I chose C, but on rereading and POE I guess it should be E.

Thanks a ton in advance.
