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. Assumptions: I. Employees may feel motivated and at least maintain, if not enhance, their present work level. II. 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.
