Model Answer
India's postal network handles a large volume of mail, but a single uniform system cannot efficiently manage the high density and speed requirements of large towns and cities. To solve the problem of delayed delivery in urban areas, six special mail channels were introduced: Rajdhani Channel, Metro Channel, Green Channel, Business Channel, Bulk Mail Channel, and Periodical Channel.
This reveals that a one-size-fits-all postal system becomes inadequate as urban demand grows. Differentiated channels are needed to ensure quick and efficient delivery based on the type and volume of mail.

Explanation
- The question asks two things: (1) the problem, and (2) what the introduction of special channels reveals — address both clearly.
- The passage directly states these six channels were introduced "to facilitate quick delivery of mails in large towns and cities" — use this as your core point.
- The "limitation revealed" part requires a small inference: a uniform system cannot handle urban volume/speed needs. Keep it brief but explicit.
- Naming all six channels earns full marks and shows textbook accuracy.
