Statement : In one of the worst accidents in railway level crossing, fifty people died when a bus carrying them collided on to a running train. Courses of Action : I. The train driver should immediately be suspended. II. The driver of the bus should be tried in court for negligence on his part. III. The railway authority should be asked to man all its level crossings.

The correct answer is: Only III follows.

The statement does not provide enough information to determine whether the train driver or the bus driver was at fault. Therefore, it is not possible to say that either of them should be suspended or tried in court. However, the statement does indicate that the railway authority should be asked to man all its level crossings. This is because manned level crossings are much safer than unmanned level crossings.

Here is a brief explanation of each option:

• Option A: None follows. This is the correct answer because the statement does not provide enough information to determine whether the train driver or the bus driver was at fault. Therefore, it is not possible to say that either of them should be suspended or tried in court.
• Option B: Only I and II follow. This option is incorrect because the statement does not provide enough information to determine whether the train driver or the bus driver was at fault. Therefore, it is not possible to say that either of them should be suspended or tried in court.
• Option C: Only III follows. This is the correct answer because the statement does indicate that the railway authority should be asked to man all its level crossings. This is because manned level crossings are much safer than unmanned level crossings.
• Option D: Only II and III follow. This option is incorrect because the statement does not provide enough information to determine whether the train driver or the bus driver was at fault. Therefore, it is not possible to say that either of them should be tried in court.
• Option E: None of these. This option is incorrect because the statement does provide enough information to determine that the railway authority should be asked to man all its level crossings.
