Critical reasoning — identify implicit assumptions: Statement: All employees are notified that the organisation will provide transport facilities at half cost from the nearby railway station to the office, except for those who already receive a travelling allowance. Assumptions: I. Most employees will travel by the office transport. II. Those who receive a travelling allowance will not read such notices.

Introduction / Context:
This administrative notice offers subsidised transport from the railway station to the office, excluding employees who already receive a travelling allowance. The reasoning task is to decide which assumptions are necessary for issuing such a notice.

Given Data / Assumptions:

• Policy: Half-cost office transport is offered from the station; employees with travelling allowance are excluded.
• Assumption I: Most employees will use the transport.
• Assumption II: Employees with travelling allowance will not read the notice.

Concept / Approach:
A notice requires only that some relevant employees exist and that they be informed. It does not require that “most” will use the facility, nor does it presume that a particular subgroup will ignore the announcement. The exclusion clause merely clarifies eligibility.

Step-by-Step Solution:

Verification / Alternative check:
Negate I: Even if most employees do not use it, informing them remains appropriate. Negate II: Even if allowance-holders read it, the exclusion still needs to be stated.

Why Other Options Are Wrong:

• Only I / Only II / Either / Both: Each adds unnecessary claims about participation rates or readership that the notice does not require.

Common Pitfalls:
Assuming that policy announcements presuppose majority use, or that exclusions imply ignorance by the excluded group.

Final Answer:
Neither I nor II is implicit
