In this question, a statement is given followed by two courses of action numbered I and II. It is required to grasp the statement, analyze the problem or policy it mentions and then decide which of the courses of action logically follow / most appropriate.Statement:As many as ten coaches of a passenger train have derailed and blocked both pairs of the railway tracks.Courses of action:I) The railway authorities should immediately send men and equipment to the spot to clear the railway tracks.II) All the trains running in both the directions should be diverted to other routes.
Correct answer: E. If both I and II follow
- A. If only I follows
- B. If only II follows
- C. If either I or II follows
- D. If neither I nor II follows
- E. If both I and II follow
Explanation
The correct answer is Option E: If both I and II follow. When a train derails and blocks tracks, two immediate actions are required: first, clearing the tracks to restore them to service, which is addressed by Action I; second, managing the impact on current train traffic, which is addressed by Action II. Both actions are complementary and necessary to address the problem comprehensively. Option A and B, which suggest only one action is sufficient, fail to address the entirety of the situation. Option C is incorrect because the actions are not interchangeable but rather both are essential. Option D is incorrect because ignoring both actions would exacerbate the situation, causing prolonged disruptions and possibly endangering safety.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
