jason has a basketball-shaped ornament, a box, and two paper cups. how many circular cross sections will jason have if he makes parallel cuts to all of the shapes vertically

The basketball-shaped ornament and the paper cups have circular cross sections when cut vertically. The box, on the other hand, will have rectangular cross sections.

Therefore, if Jason makes parallel cuts to all three shapes vertically, he will have three circular cross sections from the basketball-shaped ornament and two circular cross sections from the two paper cups, for a total of five circular cross sections.
