Difficulty: Easy
Correct Answer: Only II is implicit
Explanation:
Introduction / Context:Announcing an exam date encodes certain basic premises about the feasibility of holding that exam. We must uncover which assumption(s) are necessary for the announcement to be meaningful without overstating the case.
Given Data / Assumptions:
Concept / Approach:The essential requirement is the institution’s operational status on the specified date. Universal attendance (I) is not required; examinations proceed even with absentees. The preparation window (III) is a student strategy issue, not a prerequisite for scheduling an exam.
Step-by-Step Solution:
II is necessary: exams cannot be conducted if the college is closed. Hence implicit.I is not necessary: some students may be absent; the announcement still stands.III is not necessary: the professor’s announcement does not presume a specific study pattern.Verification / Alternative check:
Negate II (college closed): the announcement becomes infeasible, contradicting the statement’s purpose. This confirms II.Why Other Options Are Wrong:
Options including I or III assume extra details not required for scheduling.“None of these” ignores the operational premise in II.Common Pitfalls:
Interpreting an exam announcement as a claim about students’ intentions or study strategies.Final Answer:Only II is implicit
