Welcome to another round of Questions of The Week!

Questions of the week:

Introduction and requirements:

A member of the Award Committee will post a question, at a random day/time.

A competing member may make one post per question thread to answer the question and the member’s winning entry must have all parts of the question answered completely in that one post. Editing your one answer post allowed will result in disqualification.

Winnings will be limited to no more than 6 times in a given year, the objective is to allow as many Members a chance to win as possible.
Any disregard to the above and divulging the correct answers will forfeit the weekly winnings.

So please refrain from participating if you have already won in the maximum for the Year.
