One of the best ways to learn about different kinds of habitats is to go to your local zoo. Zoos are usually set up by habitat. African animals are often together. Elephants, zebras, lions, rhinoceroses and monkeys are in the same habitat. Australian animals, such as koalas, kangaroos, platypuses and emus are kept in another section. Some parts of the zoo keep animals in indoor habitats. It is easier to control the temperature in indoor habitats. This keeps the animals from getting too hot or too cold. Snakes and reptiles are kept in indoor habitats. Penguins are often kept inside as well. Birds are kept in aviaries. Aviaries are large enclosed spaces that seem like the birds' natural environment. Aviaries keep birds from escaping and keep other animals away from them.

Zookeepers are people that work at zoos. They have studied animals and know how to care for them. Zoos often have animals that are sick. Zookeepers work to make the animals better. Zoos also keep animals that are endangered. There are many programs that breed endangered animals. Zookeepers help the animals transition to life in their natural environments. Then they let them back into the wild. A visit to the zoo teaches people a lot about animals and their habitats.

It was in 1953 in Europe when many people first started owning a television set. They bought a television set for the sole purpose of watching the coronation of Queen Elizabeth II in London. Only a few thousand people were allowed into Westminster Abbey. However, live coverage allowed millions of people around the world to watch the coronation.

Another significant event was the moon landing in 1969. Again, millions of people around the world watched as Neil Armstrong walked on the moon and planted an American flag there to serve as a reminder of the great accomplishment of the crew. This time the event was broadcast in colour. The programme was much more realistic than the previous ones.

The underlined word "aviaries" as used in the text most probably means.
