Explanation:

Step1: Analyze the pyramid cross - section

When a pyramid is sliced parallel to its base, the cross - section has the same shape as the base. If the base of the pyramid is square, a parallel slice gives a square cross - section. In this case, the cross - section of the pyramid is a square.

Step2: Analyze the cylinder cross - section

When a cylinder is sliced at an angle (not parallel to the base and not perpendicular to the base), the cross - section is an oval.

Answer:

1. a) square
2. a) oval
