Mike and Tom divide a pizza that is one-half vegetarian and one-half not. Determine the false statement.
a. Only Tom is a vegetarian. If the pizza is cut into such a way that both parts have a half of vegetarian and a half of not vegetarian, then a cut satisfies criterion 1 of a fair division problem. b. Only Mike is a vegetarian. If the pizza is cut into such a way that one part is full vegetarian and another is full not vegetarian, then a cut doesn’t satisfy criterion 1 of a fair division problem. c. Both Tom and Mike are vegetarians. If the pizza is cut into such a way that one part is one-third vegetarian and one-six not vegetarian, the other part is one-third not vegetarian and one-six vegetarian, then a cut satisfies criterion 1 of a fair division problem. d. All statements are true.
