I had a couple of discrepancies raised with my answers on Saturday night and I have checked them this morning.
First one was what is MMDXCIII when converted to arabic numbers, I had 2613 as the answer but it is incorrect, it is in fact 2593. I must have been a bit lexdyslic and used MMDCXIII which is 2613.
Second was what number Olympiad is the Beijing olympics? My answer was the 29th which is correct. XXIX is on the official www.olympic.org website! The reason it is 29 and not 26 (which was suggested) is that despite missing 1 game during WW1 and 2 during WW2 - they kept counting the games as if they had played them. http://en.wikipedia.org/wiki/Olympic_Games
At least I got that roman numeral conversion correct!!
Finally a few people though my answer to "what is the earths outer layer of surface soil or crust called?" being the Lithosphere, was incorrect. A few people thought the Lithosphere was part of the atmosphere, trust me I have confirmed this also, if we were living in part of the atmosphere TIF wouldn't have to visit the perfume garden quite as much!!!
