	I don't believe a false premise automatically makes a conditional statement true. Example: If the Yankees lose 162 games, then they will win the World Series. This statement is false because no team losing 162 games can possibly win the World Series. Yet, per your logic, the statement would rate as "true" because the premise is false (the Yankees did not in fact lose 162 games). I would argue that #s 3-10 are all false because any of them would be self-contradictory, if true.

	DweezilG... that's kind of the point, exploiting the loopholes in the "standard rules of logic". Also that example about the 162 games is kind of weak, since they don't automatically contradict each other logically, even though it hasn't happened, technically it's completely possible for a team, in its entire history record, to have both 162 losses and a World Series victory at one point.

	If the premise is false, the answer is false.
