According to the rules of the university’s housing lottery, the only students guaranteed dormitory rooms are fourth-year students. In addition, any fourth-year student on the dean’s list can choose a dormitory room before anyone who is not a fourth-year student.

Summary
The rules of the university’s housing lottery are as follows:
If a student is guaranteed a dorm room, they are a fourth year student. (”the only” introduces the sufficient condition.)
If a fourth year student is on the dean’s list, he or she can choose a dorm room before anyone who is not a fourth year student.

Strongly Supported Conclusions
If someone isn’t a fourth year student, they are not guaranteed a dorm room. In addition, they cannot choose a dorm room before any fourth year student who is on the dean’s list gets to choose.

A
Benizer is a fourth-year student who is not on the dean’s list, so she is not guaranteed a dormitory room.
Unsupported. We know that anyone who is guaranteed a dorm room is a fourth year student. So, it’s possible Benizer, as a fourth year student, can be guaranteed a dorm room. The dean’s list doesn’t matter for the rule concerning guaranteed dorm rooms.
B
Ivan and Naomi are both fourth-year students but only Naomi is on the dean’s list. Therefore, Ivan can choose a dormitory room before Naomi.
Unsupported. We know that fourth year students on the dean’s list can choose before anyone who isn’t a fourth year. But Ivan isn’t on the dean’s list. So we have no idea whether Ivan can choose before anyone else.
C
Halle, a third-year student, is on the dean’s list. Thus, she is guaranteed a dormitory room.
Antisupported. Anyone who is guaranteed a room is a fourth year student. Since Halle isn’t a fourth year student, she is not guaranteed a dorm room.
D
Gerald and Katrina are both on the dean’s list but only Gerald is a fourth-year student. Thus, Gerald can choose a dormitory room before Katrina.
Strongly supported. Katrina is a fourth year student on the dean’s list. So, she can choose a room before anyone who isn’t a fourth year student, such as Gerald.
E
Anissa is a fourth-year student who is on the dean’s list. Thus, since Jehan is a second-year student who is also on the dean’s list, he can choose a dormitory room before Anissa.
Antisupported. Fourth year students on the dean’s list can choose before anyone who is not a fourth year student. So, Anissa should be able to choose before Jehan.
