premise: Arbutus College owns exactly four houses that it leases to faculty or students. Of these houses, no two are exactly the same distance from Arbutus's campus, and each house is either a student house (occupied entirely by students) or a faculty house (occupied entirely by faculty). The lease length for each house is one, two, or three semesters. The following conditions must hold: No student house has a three-semester lease. At least two houses each have longer leases than does the house closest to campus. Every student house (if there are any) is farther from campus than any faculty house (if there are any). Which one of the following could be a complete and accurate list of the leases of the student houses, ordered from the student house closest to campus to the student house farthest from campus?
hypothesis: one semester, two semesters, one semester
