Question

Statement: Water supply in wards A - D of the city will be affected by about 25% on Friday because repairing work of the main lines is to be carried out.
Conclusions I The residents in these wards should economise water on Friday.
II The residents in these wards should store water on the previous day.

Answer 1

The statement above is the information given to the residents in advance, so as to minimise their inconvenience. Since water supply is going to be affected, the residents should economise their water consumption on that particular day and they should store sufficient water on the previous day itself.
Hence, Both conclusions I and II follow.
