Liz: Thanks for inviting me to the rice-cooking festival, Ba. Can you explain what is happening?
Ba: Sure. There are three competitions:water-fetching, fire-making and rice-cooking.
Liz: Where does the water come from?
Ba: There’s a river about one kilometer away. One person from each team has to run to the river. There are four bottles of water on the river bank and each runner must take a bottle and return to the starting position.
Liz: That man seems upset. What did he just yell?
Ba: He urged his teammate to run faster.
