Statements: Water supply in wards A and B of the city will be affected by about 50% on Friday because repairing work of the main lines is to be carried out.
Conclusions:
1. The residents in these wards should economise on water on Friday.
2. The residents in these wards should store some water on the previous day
Answer: E
Clearly, the information has been given beforehand so that the residents can collect water on the previous day and use less water on Friday. So, both I and II follow.
