This document contains a mathematics test for 7th grade students on the topic of sets. The test has 10 multiple choice questions covering concepts like Venn diagrams, set operations, and set notation. It also includes one bonus question asking students to calculate the number of people who liked products A and B but not C based on survey data. The test instructions specify that students must choose one of three given question types (A, B, or C), show their work clearly, and cannot change question types once selected.
