Statement — Take a ferry or a boat instead of a bus to reach the Kravi island faster.\n\nAssumptions —\nI. Because the island is remote, it is not easily accessible.\nII. Ferries and boats are available to travel to the Kravi island.

Introduction / Context:
The advice recommends a mode switch (water transport over road) to save time. For this to be meaningful, water transport must actually be available and capable of serving the route. The statement does not require any claim that the island is generally “not easily accessible”; it only compares relative speed between two modes given availability.

Given Data / Assumptions:

• Advice: choose ferry/boat instead of bus to reach faster.
• I: claim of remoteness and general inaccessibility.
• II: existence and operability of ferries/boats to Kravi.

Concept / Approach:
To be actionable, the recommendation presupposes that ferries/boats run to the destination (II). Remoteness (I) is not necessary; even accessible islands can be reached faster by water than by road detours.

Step-by-Step Solution:

Verification / Alternative check:
If no ferry existed, the advice would be impossible to follow, making II essential. Whether the island is remote has no bearing on the comparative speed if both modes exist.

Why Other Options Are Wrong:

Common Pitfalls:
Confusing “faster” with “only feasible.” The statement is about speed, not overall accessibility.

Final Answer:
Only Assumption II is implicit.
