Social Science (087) — AI-generated practice question

First-class mail: Cards and envelopes are considered first-class mail. They are airlifted between stations, covering both land and air routes, ensuring faster delivery.

Second-class mail: It includes book packets, registered newspapers, and periodicals. These are carried by surface mail, covering land and water transport, making delivery slower and cheaper.

• The answer must clearly distinguish both classes — one mark each.
• Key contrast: airlifted (faster) vs. surface mail (slower) — examiners look for this difference.
• Also mention what each class contains (cards/envelopes vs. book packets/newspapers/periodicals).
• Avoid writing extra information about mail channels; it is not asked.
