If Daily Doubles were 100% random, they would be located in the 3 higher slots more than 50% of the time because those slots make up 60% of the board. Of course the real article http://www.mentalfloss.com/art... states that when IBM's Watson analyzed Jeopardy it discovered that Daily Doubles actually were more likely to be placed in the highest 2 slots indicating non-random placement.

What the study found was that in the early grades, the marks given by the teacher were better predicted by "attentiveness, task persistence, eagerness to learn, learning independence, flexibility and organization" than by test scores and the outcome was that girls received better marks than boys. This could lead to boys developing a feeling that school is unfair so they'll put less effort into it. Also, some might be routed into classes below their ability, making them bored and unlikely to get into the college-favored honors and AP classes.
The hard part, as always, is figuring out how to use these findings in order to maximize the achievement of all students.

The point of one antenna per customer is to avoid the rebroadcast and carriage fee issue. They aren't rebroadcasting into the air, or even into a shared CATV (community access television) cable. They are "retransmitting" portions of the freely received signal privately over the internet. It seems logical that this should be legal, but logic left the intersection of copyright and technology long ago.
