\subsection{World Quizzes}
We define several types of quizzes and implement algorithmic
-procedures to generate randomly example from each.
+procedures to generate randomly as many examples from each that we
+need.
In these quizzes, the prompt is made of three grids $A, f(A), B$ and
the solution is a single grid $f(B)$.
