My suggestion to contactees is this:
If you are in contact with an extraterrestrial intelligence,
it would be a good idea to ask for the solution of some of these problems. If you
have a positive answer, this will be the evidence that legitimizes your source
as not terrestrial or at least non-human.
I think that the given solution will tell us more than a
thousand words.
