Passage Summary: At this university, seniors are the only ones guaranteed a dorm room, and seniors with high grades get to pick their rooms before anyone who isn't a senior.

Reasoning: The university housing rules state that only fourth-year students have a room guarantee and that fourth-year students on the dean's list have priority over all non-fourth-year students.

Analysis: Since this is a 'Most Strongly Supported' question, we must treat the provided rules as absolute facts and look for a logical deduction. We know that if a student is not in their fourth year, they are not guaranteed a room. We also know that a specific subset of seniors (those on the dean's list) will always pick before any underclassman. Look for an answer that combines these constraints, such as the fact that some non-fourth-year students might not receive housing or that dean's list seniors have the highest priority relative to non-seniors.
