UFOs are strange flying objects that some people report they have seen in the sky and believed to be spacecraft from another planet. Many scientists do not believe so. They say that if people see a UFO, it might be an aircraft, a weather balloon or meteor. However, there is still evidence for people to believe in the existence of UFOs.

In 1947, Kenneth Arnold, an experienced pilot in the USA, reported that he saw nine large round objects traveling at about 2, 800 meters an hour to the left and north of Mount Rainier.

In 1952, there were more than 1,500 UFO sightings around the world.

In 1954, a woman and her children believed they saw a UFO above their house. The woman said she saw two aliens in the spacecraft.

In 1964, a farmer claimed he saw an egg-shaped object in one of his fields and also aliens collecting soil samples.

In 1971, two men claimed they were captured by aliens and taken abroad a spacecraft. After being examined by the aliens, the men were free.

In 1978, a young pilot and his plane disappeared after sighting a UFO.

In 1981, Renato Nicolai, who was living in the south east of France, reported that he saw a plate-like device at a treetop 30 meters away from his garden.

Read the passage and choose the correct answer to complete the sentence:
A UFO (Unidentified Flying Object) is an object flying in the sky which cannot be identified by the person who sees it. Sometimes the object is investigated. If people can still not figure out what the object is after an investigation, it is called a UFO. If they figure out what the object is, it can no longer be called a UFO because it has been identified.
Even though UFOs can be anything, people often use the word UFO when they are talking about alien spacecraft. Flying saucer is another word that is often used to describe an unidentified flying object.
