Read the passage, then decide if the statements that follow are true or false (1.0 pt)
Nowadays, many families are worried about their water bills. Some of the bills are enormous. In fact, they
can save their money if they try to reduce the amount of water their families use. There are some easy ways
to do this. First get a plumber to make sure there are no cracks in the pipes. Seconds, do not use baths
because they use twice as much water as shower; take showers instead. And last but not least, remember to
turn off the faucets since a dripping faucet can waste up to 500 liters of water a month. By doing these
things, we can both save our own money and water for future generations.
