Do you know what is this ???
The first who will repply with a corect and detailed answer, will get from me a 0.3 SBD prize.
(not much, but the task is very easy, isn't it ?)
TO QUALIFY for the prize, you must upvote, and resteem this post to atleast 300 of your followers .
Sorry, plankton, if you got <300 on your list, this time it is not for you. Wait for my new puzzles.
However, if you try desperate & hard, I may concider a second, promotional prize. :)
