Difficulty: Easy
Correct Answer: Both I and II are implicit
Explanation:
Given data
Concept/Approach
An advisory to refuse leave presupposes both the authority to deny and a factual basis (work pressure) for refusal.
Step-by-Step reasoning
1) Without the possibility of refusal, the advice would be meaningless ⇒ I is implicit.2) Citing 'exigency of work' implies the supervisor is aware of work needs ⇒ II is implicit.
Verification/Alternative
Remove either assumption and the advice loses sense: either it cannot be acted upon (no authority) or it lacks justification (no workload check).
Common pitfalls
Final Answer
Both I and II are implicit.
