Lizards   are unusual,but they can make good pets because most of them are small and easy to care for. They do not make loud noises,and they do not need to go for walks or take baths. Of course, some lizards make better pets than others. One of the most popular lizards in pet store is the bearded dragon. Bearded dragons are active during the day and do not mind people holding them. Geckos are another popular pet lizard. They are a little more difficult to care for. Geckos are active at night and need a warm place to live.Like bearded dragons,they can be held by their owners.Both of these lizards can live ten years or more when they are well cared for. Two lizards that are bad choices for pets are iguanas and chameleons. Iguanas can grow to be almost two meters(nearly six feet),so they need a big space to live in.They can also bite or scratch   their owners.Chameleons do not hurt their owners,but they are quite difficu1t to care for. While iguanas can live up to twenty years,chameleons do not live very long. Most do not live more than five years. The writer of the passage probably thinks that  _  .
iguanas are not good pets for children all lizards are good pets most lizards are dangerous,so do not keep them as pets no matter which lizard you get,do not hold it
