In each question below is given a statement followed by two courses of action numbered I and II. You have to assume everything in the statement to be true and, on the basis of the information given in the statement, decide which of the suggested courses of action logically follow(s) for pursuing.

Statement: A large number of people in ward X of the city are diagnosed to be suffering from a fatal type of malaria.

Courses of Action:

I. The city municipal authority should take immediate steps to carry out extensive fumigation in ward X.

II. The people in the area should be advised to take steps to avoid mosquito bites.

  1. A.

    Only I follows

  2. B.

    Only II follows

  3. C.

    Either I or II follows

  4. D.

    Neither I nor II follows

  5. E.

    Both I and II follow

Correct answer: E

Concept

A suggested course of action logically follows only if it is a practical, well-recognised step that directly tackles the problem in the statement or its cause. Several courses can follow at the same time when each one independently helps and they do not conflict with one another; they follow together whenever they are complementary rather than substitutes.

Applying it to this statement

The problem is an outbreak of a fatal type of malaria in ward X, and malaria spreads through mosquitoes. Judge each proposed step against that cause:

  • Fumigation in ward X destroys the mosquito population at its source, attacking the cause of the outbreak — a standard, practical control measure, so it follows.

  • Advising residents to prevent mosquito bites lowers the chance of transmission for each person while the vector is being cleared — an independent, sensible precaution, so it also follows.

Both steps are practical, act on different links of the same chain, and do not clash, so the two courses follow together.

Why the other choices do not hold

  • Restricting the response to a single step drops a second measure that independently helps — an unwarranted exclusion.

  • Reading the two as an 'either/or' choice treats them as substitutes, but they are complementary and can run together.

  • Rejecting both ignores the direct link between mosquitoes and the malaria outbreak.

Hence the course of action that holds is: Both I and II follow.
