Answer this simple question to get Google Wave Invite

I have some Google Wave Invitations left. And I am getting crazy this time. Just answer a simple question correct and lucky winners selected via a lucky draw will get these invites.

The winner has been selected by True Random Number Generator.

~~This contest is open till November 12, 23:59:59 (IST, UTC+5.5).~~
The contest is closed now and the winner is: lpetre. Congratulations to lpetre and thanks to all for participation. I will let you know if I will have more invitations to share. So be in contact. You can subscribe my feed or follow me at twitter for further notification.
