Question
The major road connecting the two main parts of the city
is inundated due to heavy rains during past two days. Courses of Action: (I)The govt. should immediately send a relief team to the affected area. (II)The municipal authority should make immediate effort to pump out water from the road. (III)The municipal authority should advise the general public to stay indoors till the water is cleared.Solution
Statement II is a reasonable course of action as it would help in clearing the road for traffic. As the statement I only mentions that the road is inundated due to heavy rains, while III course of action does not explicitly tell that whether the water is cleared by the municipal authority or as a natural proces. Hence, it isI and III are not a necessary action,
