Read the passage carefully, then choose the best answer for each question.
HAVE ALIENS VISITED US?
Many people have stories about seeing aliens. Here are two.
Judy Varns works for a group called the Mutual UFO Network. The purpose of this group is to research UFO sightings. Varns thinks a place called Area 51, in Nevada in the U.S., may be the best place on Earth to see UFOs. One day, she took some photos in the area and saw something she thinks is a UFO. "We saw this little disk-shaped thing in our photos. It's kind of exciting," she says.
Pat Travis lives near Area 51. One night, she saw a strange light in the sky. The light's movements were very unusual. Travis saw the lights move sideways and up and down. She saw them make many strange moves. Travis thinks it was a UFO.
Secrets of Area 51
Some people think Area 51 is where the U.S. Air Force keeps secrets, like UFOs that came to Earth and the aliens inside them. But really, Area 51 is a place the U.S. Air Force uses to test new technology, such as new kinds of aircraft.
James McGaha is a pilot who flew airplanes at Area 51. "There is absolutely no UFO activity at Area 51," he says. "No flying saucers, no live aliens, no dead aliens."
So what did Varns and Travis see? Bill Fox worked at Area 51, too. He thinks he knows the answer. "We did build some strange-looking airplanes," he says. "I could see why some people would think they were UFOs."
So are UFOs real? You'll have to decide for yourself. But if you do visit Nevada, keep your eyes on the skies!

B.He made airplanes.
