system where I do something like print a conextual question such as:
who is the president of the USA ?
here are 4 words, cat, dog, run, frog. Which one is a verb and which
of the others is not a mamal ?
However, I may need some way of randomly generating numerous
questions and I suppose if this was a good approach there would be
