Statement & Assumption — “Railway wagons of Eastern Railway will carry your message,” says an advertisement by Eastern Railway. Which assumptions are implicit? I. Other railways already run such schemes profitably. II. This advertisement will elicit responses (i.e., advertisers will come forward).

Introduction / Context:
An advertisement invites customers to use railway wagons as a medium. Ads presuppose an audience that may respond; they do not need benchmarking proof about other railways’ profits.

Given Data / Assumptions:

• Service: branding/advertising on wagons.
• Channel: public advertisement.

Concept / Approach:
Assumption II is necessary: without expecting responses, the ad would be pointless. Assumption I is nonessential; even if others do not run such schemes, Eastern Railway can pioneer it.

Step-by-Step Solution:
II: Implicit—ads are calls to action.I: Not implicit—competitor precedent/profitability is not a prerequisite to advertise.

Why Other Options Are Wrong:
Options including I add unnecessary market-history claims.

Final Answer:
Only Assumption II is implicit.
