The line numbers in the questions may not refer correctly to the right line in the passage.

It's a pleasure that I could help you in your preparation but I am sorry to say that I DO NOT
have explanation for the answers and the source of all these RCs are located here at eSnipes.
I take no responsibility of the source as I DO NOT know the real auther or collector of all those
RC questions in there. I only created this site by taking data from the above mentioned source.
So asking me for explanation of any kind will be futile.
