Statement: There have been many instances of derailment of trains due to landslide in the hilly areas which caused loss of many lives.
Courses of Action:
1. The railway authority should arrange to deploy pilot engines before the movement of passenger trains in the hilly areas to alert the trains in case of any landslide.
2. The railway authority should strengthen the hill slopes by putting iron meshes so that the loose boulders do not fall on the track.
Answer: C
Correct answer: Either I or II follows
Both courses would answer the danger, and either alone might serve: a pilot engine ahead of each train would find a blocked line before the train reached it, and meshing the slopes would stop the boulders falling in the first place. Since one or the other would meet the case, the answer is either I or II.
