Question: I'm taking a test and have to guess the right answer to the question after the article. Article: Imagine one day, the water taps in your house stop running.

Probably not. But _ 's what kids in Yemen are experiencing. Experts said Yemen is going to be the first country in the world to run out of water. According to a report, the capital, Sanaa, will run out of drinking water as early as 2025. Because of the shortage, the government often cuts the water supply. Hannan, an 18-year-old from Lahej, told the Times: "In a good week we'll have a water supply all week. But then the following week there will be water only for a day or two." Hannan said only rich people have enough water to use. They can buy water from the shops or from the water truck. Private companies own the trucks. They travel around the city every day to sell water - at very high prices. "A lot of people can't afford it," she said. The average person in Yemen uses 100 to 200 cubic meters of water per year.
