É exatamente este tipo de questão que eu me recuso a discutir e sobre
o qual quanto menos falarmos, melhor. Esta lista não é para discutir
carreira docente de ninguém. O Claudio mandou para a lista uma mensagem com
uma frase acalorada, pela qual ele já pediu desculpas mais de uma vez.
Vamos encerrar o assunto, por favor.
Eu continuo aliás com a suspeita de que este professor que passou
esta questão está é rindo da nossa cara. Se o espírito for este,
eu submeto à atenção desta augusta lista esta jóia, de autoria
de James Propp, um matemático que trabalha em combinatória,
probabilidade e sistemas dinâmicos. O teste está aqui:

SELF-REFERENTIAL APTITUDE TEST, by Jim Propp (propp@math.wisc.edu)
The solution to the following puzzle is unique; in some cases the
knowledge that the solution is unique may actually give you a short-cut
to finding the answer to a particular question, but it's possible to
find the unique solution even without making use of the fact that the
solution is unique. (Thanks to Andy Latto for bringing this subtlety
to my attention.)
I should mention that if you don't agree with me about the answer to #20,
you will get a different solution to the puzzle than the one I had in mind.
But I should also mention that if you don't agree with me about the answer
to #20, you are just plain wrong. :-)
