I know there are quite a few people out there who would have loved this part of the question paper like me. Atleast I needn't awaken the creative part of my brain to write a few sentences which meant the same, but sounded different enough to make the examiner feel that I knew everything about the answer in question ;-)

Today as I sat on that chair waiting for the dentist to fill the gaps between my teeth.. I couldn't help but relate the situation with the fill in the blanks question we used to have for our examz :P
As the student in question(a well known dentist) came all set for the examination, and went through the blanks in the question, I wasn't really sure if he would get everything right. He finished his examination in 2 hours, though the TAT was 1 hour. That left me thinking was it that hard a blank to fill. 

Ma'am please have a look and let me know if this is fine.As I searched for the blanks..I gave hime a smile.. .He had filled the most appropriate fillers in those blanks spaces between my teeth so well.. he knew what to do with each and every space that was present and he did a great job. It was so fine that no one could really make out the difference until they sat and observed it for looong.. of course my Big Sis is known for her skills and did finally agree there is some change...

Gladly I reward him full marks (I must say full fees) and I gave it with a smile...a smile more prettier than the one I had before.


And if you still haven't figured out the right words for the fill in the blanks question... here are the answers :P
1 Mineral
2 Sedimentary
