III. Choose the item A, B, C or D that best answers the question about the passage. A UFO (Unidentified Flying Object) is any object flying in the sky which cannot be identified by the person who sees it. Sometimes the object is investigated. If people cannot 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 can use the world UFO when they are talking about alien spacecraft. Flying saucer is another word that is often used to describe an identified flying object. Studies estimate that 50-90% of all reported sightings are identified later. Usually 10-20% are never identified.
