"If X croaks and eats flies, X is a frog.
I can hear an animal which croaks.
From the statement above I can conclude:"
In the moodle quiz, the answer was given as 'the animal is a frog'. This is wrong: by computer-based arithmetic logic, we can't make that assumption: we would also need to know whether or not it croaks. That was my mistake - sorry!
If X croaks , X is a frog. If X sings , X is a magpie.
If X is a frog, X is brown. If X is a magpie, X is black and white.
There is an animal in the garden which sings; from the knowledge base above I conclude that it is a magpie. This is an example of . . .

If X croaks , X is a frog. If X sings , X is a magpie.
If X is a frog, X is brown. If X is a magpie, X is black and white.
I know there is a magpie in the garden because I hear it singing. I can't see it, but I deduce that it must be black and white: this is an example of . . .
