1. What allowed Cardano to justify publishing his book?
(a) He was punished as a heretic,
(b) He found del Ferro's orgininal solution to the cubic.
(c) He was dead, and the book was really published by his student.
(d) He found Fior's documents which spoke against Tartaglia.

2. Why did Cardano take an oath to secrecy?
(a) It was the only way to get Tartaglia's solution to cubic equations.
(b) It was the only way he could become a priest,
(c) It was the only way to get his book published.
(d) It was to the only way to win the contest with Fior,

3. Which of the following is true in modern math about twin primes?
(a) They are not considered whole numbers.
(b) Their sum is always another prime number.
(c) They are infinite.
(d) We don't know if they are finite or infinite.

4. Which of the following is INCORRECT, and not used in Archimedes proof of his theory?
(a) Since the diameter of a circle is equal to the hypotenuse of the right triangle, the area of the triangle in his proof is 1/2 the radius times the circumference.
(b) Since the base of the triangle is equal to the circumference and the height is the radius, the area of the triangle in his proof is 1/2 the radius times the circumference.
(c) The area of a triangle is one half the base times the height.
(d) Since the circumference can also be expressed as twice the radius multiplied by π, the area is 2πr²/2, or πr².

5. What did Dunham consider as Archimedes's "masterpiece"?
(a) Archimedes' work on volume to surface area ratios.
(b) Archimedes' work on shperes, cones, and cylinders.
(c) Archimedes' work on determining angular measurements.
(d) Archimedes' work on determining a number value for pi.
