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. Studies also show that very few UFO sightings are hoaxes (people trying to trick other people). Most UFOs are actually natural or man-made objects that looked strange. 80-90% of UFOs are identified as one of three different things: (a) astronomical causes (for example: planets, stars, or meteors); (b) aircraft; and (c) balloons. 10-20% of UFOs are other causes, such as birds, clouds, mirages, searchlights, etc. 1. Another word used to describe a UFO is _____.

Read the passage below and decide whether the statements are TRUE or FALSE? Long ago, people thought the Moon was a god and we would never be able to reach it. However, the invention of telescopes in 1608 enabled people to learn that the Moon is just another planetary body. And mankind’s dream of walking on the Moon suddenly seemed possible. The dream came true on July 20th, 1969 when Neil Armstrong, Buzz Aldrin, and Michael Collins flew to the Moon as part of the Apollo 11 lunar mission. Neil Armstrong was the first to step onto the Moon. After admiring the tranquil, desolate beauty of the Moon’s surface, Neil Armstrong and Buzz Aldrin completed their mission, while Collins stayed in orbit to maintain the systems on board the spacecraft. During the stay of more than twenty-one hours on the Moon’s surface, the astronauts found no rain or wind at all. The Moon was like a desert with plains, mountains, and valleys. The surface was covered with dust, which was so thick that they left footprints where they had walked. They left a United States of America flag there and return to Earth with forty-six pounds of moon rock for scientific study.People have known all about the Moon for thousands years
