Concept:
- In Statement and Courses of Action questions, assume the statement is completely true.
- A course of action follows only if it is a practical, reasonable, and directly relevant step to deal with the problem in the statement.
Step 1: Read the statement carefully.
The roads of city 'X' have deteriorated because of continuous rain over the last twenty days.
Step 2: Check Course of Action I.
Course I says the civic authority should immediately repair the damaged roads.
This is the direct and practical solution to the exact problem stated, so it logically follows.
Step 3: Check Course of Action II.
Course II says motorists should be alerted with sign boards about the bad patches.
This is a reasonable safety measure to prevent accidents while repairs are pending, so it also follows.
Step 4: Combine the results.
Since both I and II are sensible, practical steps that directly address the situation, neither can be rejected.
Final Answer: Both I & II follow (option 3)
