Q:

In the question given below, a statement is given followed by three courses of action. A course of action is taken for improvement, follow up, etc. Read the statement carefully and give your answer.

Statement:
A knife-wielding assailant killed a 29- year-old man and injured four others in a lively neighbourhood near Paris’ famed Opera Garnier before he was killed by police on Saturday night.

Courses of Action:
I. The government should ban the sale of knives in all major cities.
II. Any person seen carrying a knife should be immediately taken into police custody.
III. Policemen should be posted near all major tourist spots to avoid such untoward incidents.

A) Only course of action I follows B) Only course of action II follows
C) Both I and II follow D) Both II and III follow
 
Answer & Explanation Answer:

Explanation:

None of the courses of action follow. Banning the sale of knives just because one particular knife-wielding assailant went on a rampage makes no sense. Similarly, taking into police custody all those who are seen carrying knives is not something practical. Knives can be used for so many other purposes not involving the killing/harming of people. Finally, it is not a realistic expectation that posting policemen in all major tourist spots would reduce or altogether stop instances of such occurrences. Therefore, option E is the correct answer.
