Read the passage below and decide whether the statements are TRUE or FALSE?

This report shows how the rice-cooking festival was held. The festival was held in the communal house yard about one kilometer away from a river. There were three competitions: water-fetching, fire-making and rice-cooking. The festival lasted one day. In the water-fetching contest one person from each team had to go to the river to get the water. In the fire-making contest two team members had to make a fire in the quickest way. They tried to rub pieces of wood together to make the fire. Members from each team took part in the rice-cooking contest. They had to separate the rice from the husk and then cook the rice. After the three contests, all the points were counted and the Thon Trieu group won the grand prize. The festival was wonderful.
