Statement: The head of the organization congratulated the entire staff for their sincere efforts to reduce the deficit and urged them to give their best for an even more profitable future.\nAssumptions:\nI. Employees may feel motivated and at least maintain, if not enhance, their present work level.\nII. Employees may now relax and slow down since there is no immediate threat of a huge deficit.

Introduction / Context:
This managerial communication aims to reinforce positive behavior (deficit reduction) and set a forward-looking target (profitability). We must determine which assumption is necessary for the message to achieve its persuasive purpose.

Given Data / Assumptions:

• Leader praises staff for measurable improvement.
• Leader urges continued or increased effort for better results.
• Organizational goal: move from reduced deficit to higher profit.

Concept / Approach:
Motivational appeals assume that praise and vision-setting can influence effort. An opposite assumption that people will relax would undercut the very intent of the speech and is therefore not implicit.

Step-by-Step Solution:
1) The speech's purpose is to motivate; thus it presupposes staff responsiveness to recognition and exhortation (I).2) Assumption II conflicts with the intent. A communicator would not rely on staff relaxing post-praise; that would defeat the message's goal.

Verification / Alternative check:
If employees did not respond to praise and urging, the speech would be pointless. Hence I is necessary; II is contrary to purpose.

Why Other Options Are Wrong:

• Only II: Contradicts the persuasive aim.
• Either/Neither/Both: Do not reflect the motivational logic embedded in the communication.

Common Pitfalls:
Mistaking a possible reaction (complacency) for an assumed one. The assumption must support, not negate, the intended effect.

Final Answer:
Only assumption I is implicit.
