Article: Car sharing is another way to drive green that's gaining in popularity, especially in urban areas.People who may not drive every day but still want a car to run errands or drive on weekends benefit most from car sharing.Car sharing is usually run by a service like Zipcar, though there are non-profit and informal car sharing services.Members pay a monthly fee and have access to an entire fleet of cars when they need one.The cars are parked in fixed spots around the city, so members only need to make a reservation, and then go to the pickup spot. Car sharing has major environmental benefits because it reduces the number of cars on the road.Members don't drive just because they are in a car.They plan trips, and if they don't need a car, they don't use one.Still, a car is available to them if they need to make a big trip to the grocery store, pick someone up at the airport or if they want to go to the beach for the day.Members also benefit by having access to a car without any of the headaches of ownership.They usually don't have to pay for the gas, insurance or maintenance , and the monthly membership fee is less than a typical car payment.So if you really want to go green but aren't ready to totally give up a car yet, car sharing may be the way to go. If you still need to get around, but want to go even greener than sharing a car, share a bus! Question: The author intends to tell us that car sharing _ . Yes or no, is the answer "is becoming more and more popular in cities"?
No

Article: It is sometimes reported that strange flying objects have been seen high up in the sky. People call these strange objects Unidentified Flying Objects(UFOs). These UFOs caused a lot of interest. Some of the reports about them are difficult to believe.Some have been explained in scientific ways. Others have never been explained. Here is an account of UFOs from a report. Dennis Bardens,who wrote an article,tells us that he once saw a UFO himself.He was having dinner one night with a friend near Tripoli ,Libya ,and after dinner the two men walked across a yard to his room to look at some papers.Bardens noticed that the moon looked strange that night. "It wasn't the moon,"was the reply. They watched the light and saw that it was moving.It seemed to be an object rather like a big plate.In some ways it looked like smoke with a light on it,but it wasn't smoke because it didn't change its shape.It was moving in a regular way.That is to say,it didn't go suddenly faster or more slowly,and it didn't go higher or lower.So the two men decided that there must be men in it. When it came nearer to Libya,Bardens said that he felt eyes looking at him.He was being watched in the darkness. When it was nearer,they noticed that the bottom parts were brighter than the top.The bottom was yellow and the top was red.Then the object suddenly turned away and left Libya,moving very fast. On a later day Bardens talked to other people about it,and he found some who had seen it.They all described it in the same way.Could they all the mistaken? Question: A UFO was seen one night _ . Yes or no, is the answer "when they were walking across a yard to Bardens' room"?

Article: We don't have beds in the space shuttle, but we do have sleeping bags. During the day, when we are working, we leave the bags tied to the wall, out of the way. At bedtime we untie them and take them wherever we've chosen to sleep. On most space shuttle flights everyone sleeps at the same time. No one has to stay awake to watch over the space plane: the shuttle's computers and the enginers at the Control Office do that. If anything goes wrong. The computers ring a warning bell and the engineers call us on the radio. On the space shuttle, sleep-time doesn't mean nighttime. During each ninety-minute flight around the earth, the sun "rises" and shines through our windows for about fifty minutes: then it "sets" as our flight takes us around the dark side of the Earth. To keep the sun out of our eyes, we wear black sleep masks. It is surprisingly easy to get comfortable and fall asleep in space, and we sleep differently. Some sleep upside down, some sideways, some right side up. When it's time to sleep, I take my bag, my sleep mask, and my tape player with earphones and float up to the flight platform. Then I get into the bag, and float into a sitting position just above a seat, right next to a window. Before I pull the mask down over my eyes, I relax for a while, listening to music and watching the Earth go by under me. When I'm in space I don't need as much sleep as I do on Earth Maybe that's because when I am weightless, I don't feel as tired. Or maybe it's because I'm excited to be in space and don't want to waste time sleeping. Question: What does the passage mainly talk about? Yes or no, is the answer "How they sleep in space"?
No
