meat remains raw inside or becomes burnt outside (or both).

Therefore we can infer that:

The great mathematician Countalot discovered the Incredible numbers; he does not know yet if they are finite or infinite, but he made the following conjecture:

If they are infinite, then at least one of them has 8 distinct prime factors.

One of his students, Countagain, showed that Countalot’s conjecture is false. Therefore he proved that:

if Incredible numbers are finite, then none of them has 8 distinct prime factors

if Incredible numbers are finite, then all of them have 8 distinct prime factors

Incredible numbers are infinite

Incredible numbers are infinite and none of them has 8 distinct prime factors

Incredible numbers are infinite and all of them have 8 distinct prime factors

Archaebacteria are single–celled organisms that live in ponds and reproduce by fission (i.e. each bacterium splits in two identical organisms). If you put one archaebacterium in a certain pond, it will reproduce by fission once a day; in 30 days, the whole pond surface will be completely covered by bacteria. How many days will it take to cover the whole surface, if we initially put two bacteria in the pond?
