4.0 deced VALID Each FR poses a question dryly and answers the previous valid FR's question (if any) amusingly.

What is the mean frequency of light in the universe?

I judge this rule to be valid.

* It is consistent with itself and its assertion is quite possible; therefore, it is not Contradictory.

* There are no earlier posted fantasy rules in this round with which it could be inconsistent.

* I can't think of a reason to declare it Illegal or Unreasonable.

* It's clearly relevant.

Therefore, I deem it valid.
