1 2 3 4 3 1. The (A * E * I * O) standard-form categorical proposition is (“Some S is P” * 4 1 2 x “Some S is not P” * “Every S is P” * “No S is P” * “Every S is not P”). 1 2 3 4 2. If you change the quality of an (A * E * I * O) proposition, then the result 2 1 4 3 is an (A * E * I * O) proposition. 1 2 3 4 3. If you change the quantity of an (A * E * I * O) proposition, then the result 3 4 1 2 is an (A * E * I * O) proposition. 1 2 3 4 4. If you change both the quantity and quality of an (A * E * I * O) proposition, 4 3 2 1 then the result is an (A * E * I * O) proposition. 1 x x 5. “No S is non-P” is logically equivalent to (“Every S is P” * “Some S is P” * “No x S is P” * “Some S is not P”). 1 2 3 2 6. “Two is even or odd” (implies * does not imply) the proposition (“Two is even” * 3 1 “Two is odd” * “Two is odd or even”). x 1 2 x 7. (Every * Some * Some but not every * No) valid argument has all true premises. x 1 2 x 8. (Every * Some * Some but not every * No) invalid argument has all true premises. x x x 1 9. (Every * Some * Some but not every * No) valid argument has all true premises and a false conclusion. x 1 2 x 10. (Every * Some * Some but not every * No) valid argument has all false premises and a true conclusion. x 1 2 x 11. (Every * Some * Some but not every * No) invalid argument has all true premises and a false conclusion. x 1 x x 1 12. (Every * No) argument is (valid * invalid * valid and invalid).
