premise: Four people—Fritz, Gina, Helen, and Jerry—have formed a car pool to commute to work together six days a week from Monday through Saturday. Each day exactly one of the people drives. The schedule of the car pool's drivers for any given week must meet the following conditions: Each person drives on at least one day. No person drives on two consecutive days. Fritz does not drive on Monday. Jerry drives on Wednesday or Saturday or both, and he may also drive on other days. If Gina drives on Monday, then Jerry does not drive on Saturday. Which one of the following could be true of one week's schedule of drivers?
hypothesis: Jerry drives on both Tuesday and Friday.
