Article: Our first winter in Canada was the happiest we have experienced. We were living in the countryside then and had just arrived from Hong Kong that autumn. One evening in mid December snow began to fall. When we looked out of the window and saw that it was snowing, we all cheered. It was the first snow we had ever seen and we were excited. We could hardly wait for the snow to stop so that we could go out to play. Next morning when we woke up, it was still snowing. We switched on the radio and learned that more than ten inches of snow had falled during the night and that since the roads were blocked there would be no school that day. We jumped up and down for joy and begged mother to let us go outside to play in the snow. She said we could go out after breakfast if we dressed ourselves warmly and promised to come back as soon as we felt cold. When we went out, the snow had almost stopped. The roads , paths, gardens, and playing grounds were all hidden under a white blanket of soft snow. It was the most beautiful sight we had ever seen. Just then, we saw some neighbour's children coming out to play. We ran over to join them. Together we built a snowman and a snow house. After that, we took turns sliding down a hill on a large piece of cardboard. We were having so much fun when supper time came. Mother almost had to force us to go in and eat. Question: The writer and his brothers and sisters built _ . Yes or no, is the answer "a snowman and a snow house with their neighbors' children"?
(Answer)
No

Article: As in the field of space travel, new technologies continue to appear in undersea exploration. They share a number of similarities with each other -- as well as some important differences. Manned submersibles , like spaceships, must maintain living conditions in an unnatural environment. While a spaceship must simply be sealed against the vacuum space, a submersible must be able to bear extreme pressure if it is not to break up in deep water. In exploring space, unmanned vehicles were employed before astronauts. In undersea exploration, on the other hand, men paved the way, and only recently have unmanned remote-operated vehicles (ROVs) been put to use. One reason for this is that communicating with vehicles in orbit is much easier than talking to those underwater. A vacuum is an ideal medium for radio communications, but underwater communications are limited to much slower sound waves. Thus, most undersea vehicles -- particularly ROVs -- operate at the end of long ropes. For a similar reason, knowing where you are undersea is much more difficult than in space. A spaceship's position can be located by following its radio signal, or by using telescopes and radar. For an undersea vehicle, however, a special network of sonar devices must be laid out in advance on the ocean floor in the area of a dive to locate the vehicle's position. Though undersea exploration is more challenging than outer space in a number of respects, it has a distinct advantage: going to the ocean depths doesn't require the power necessary to escape Earth's gravity. Thus, it remains far less expensive. Question: The purpose of the passage is _ . Yes or no, is the answer "to tell some differences between two kinds of explorations"?
(Answer)
No

Article: It was a beautiful Sunday morning, and Maggie and I were returning from our walk through the woods.We were only a couple of blocks from home when I spotted a cell phone and a credit card sitting on the road.We took them home.We always find amazing things on the street and she looks upon them as a movable feast-a chicken wing here or a barbecue rib there. I found another cell phone a few years back, too, and called a number in its phone book.I explained the situation to the guy who answered.He said it was his sister's and that he'd come to pick it up, which he did. And that was that.No verbal thank-you, no written thank-you, no "here's a box of chocolates" thank-you. I didn't have time to call anyone on my latest found cell phone.I was pouring myself coffee when it started to shake and dance across the kitchen counter. "Who's this?" someone asked when I picked up. "Who's this?" I countered ."Sarah?" She was surprised at my knowing her name until she realized her name was on the credit card."Could you send them to me?" she asked. She lives in Arlington, which is 2 miles from my house. "Hmm, no, "I replied, adding that I thought she could come to get them, and that if I wasn't at home, they would be in my mailbox. A day later, when I was out for a run, someone got them back.There wasn't even a piece of paper put in the mailbox with "Thanks" on it.In this age of e-mail and cell phone, there's really no excuse.Years ago, I found something more precious than a $100 bill on the street:a driver's license.I saw that its owner lived a couple of blocks from me, so I called him up.He asked whether I could slip the license through his front door. "I guess I could, "I replied. And that was that. Question: The writer wants to tell us through the unusual stories, Yes or no, is the answer "people should learn to appreciate persons who provide help for you"?

No
