Statement — City X traffic police launched an SMS service so commuters can learn about traffic diversions, pending challans, and the contact/location of area traffic officials by sending a text message. Question — Which conclusion necessarily follows?

Introduction / Context:The service explicitly provides traffic diversions and other information via SMS. We test whether it must thereby provide “latest updates” and whether it will “enormously” boost phone sales.

Given Data / Assumptions:

• Facility: commuters can query diversions/challans/officials via SMS.
• Nothing is stated about handset ownership trends or market demand.

Concept / Approach:If commuters can query and receive diversion information, then they can obtain traffic updates. Predicting handset sales is speculative.

Step-by-Step Solution:

Verification / Alternative check:Even if phone sales are unchanged, the service can still provide updates.

Why Other Options Are Wrong:Any option selecting II relies on unprovided market assumptions.

Common Pitfalls:Assuming every digital public service materially expands device ownership.

Final Answer:if only conclusion I follows
