Statement: There is an unprecedented increase in the migration of villagers to urban areas as repeated crop failure has put them into a precarious financial situation.Courses of Action:I. The villagers should be provided with an alternate source of income in their villages which will make them stay put.II. The migrated villagers should be provided with jobs in the urban areas to help them survive.
Correct answer: A. Only I follows
- A. Only I follows
- B. Only II follows
- C. Either I or II follows
- D. Neither I nor II follows
- E. Both I and II follow
Explanation
The correct answer is Only I follows. The primary issue is the migration of villagers due to crop failure. By providing an alternative source of income in the villages, the villagers will have less incentive to leave, thus reducing the strain on urban areas and addressing the root cause of migration. Option II, while helpful in the short term, does not address the underlying issue of rural distress and could lead to further strain on urban resources. Therefore, only Course of Action I is viable in the long term.
