Read the passage below and choose one correct answer for each question.

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 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.

Studies estimate that 50%-90% of all reported UFO 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% UFOs are identified as one of three different things: astronomical causes (for example: planets, stars, or meteors); aircraft; balloons 10%-20% of UFOs are other causes (such as birds, clouds, mirages, searchlights, etc.)

Long ago a lot of people thought the moon was God. Other people thought it was just a light in the sky. And others thought it was a big ball cheese!

The telescopes were made. And men saw that the moon was really another world. They wondered what it was like. They dreamed of going there.

On July 20th, 1969, that dream came true. Two American men landed on the moon. Their names were Neil Armstrong and Edwin Aldrin. The first thing the men found was that the moon is covered with dust. The dust is so thick that the men left footprints where they walked. Those were the first marks a living thing had ever made on the moon. And they could stay there for years and years. There is no wind or rain to wipe them off.

The two men walked on the moo for hours. They picked up rocks to bring back to earth for study. They dug up dirt to bring back. They set up machines to find out things people wanted to know. Then they climbed back into their moon landing craft.

This story tells …………….

Next day the landing craft roared as the men took off the moon. They joined Michael Collins in the spaceship that wait for them above the moon. Then they were off on their long trip back to earth.

Behind them they left the plains and tall mountains of the moon. They left the machines they had set up.

 

And they left footprints that may last forever.
