Question 1100673
.
Hello, 


let me send you, in response, couple of entertainment problems.


<pre>
1.  If a grandfather clock takes 30 seconds to strike six, how long does it take to strike 12? 


2.  Three boxes contain one ball each: white, black and green.
    The first box is labeled as "White", the second box is labeled as "Black", 
    and the third box is labeled as "White or Green", 
    but none of the labels corresponds to the box content.
    Can you identify, what ball is in each box?
