[EX Q]: Article: We were on the way from Hutchinson to Chicago for a short spring break. For many years I had wanted to take my family on the train. We all had been to Chicago four years ago, and the kids loved it. Chicago is one of my favorite cities, too, so the thought struck me again last fall to ride the train to Chicago. Of course, flying would have been faster. But I don't think flying is easier, especially these days, with all the security and waiting in lines at airports. Though we were tired in the middle of the night, the kids got on the train with the _ of this adventure. "We're moving," my son William shouted happily with big eyes as the train began to pull away from the Hutchinson station. I removed my shoes and lay down to try to finish my night's sleep. The sleeper car would have better enabled that, but the ordinary train seats were not too bad. An airline flight is a more miserable experience for me: not enough room, two hours of pain with my knees almost touching my chin, the hard seatback in front cracking my kneecaps with every move of the body planted in front of me. On the train I could almost outstretch all of my 6-foot-2-plus body in the generous legroom. The journey didn't feel at all as long as it was. We all found the train ride a joy. The car ride would have felt every minute of 13 hours. But on the train you are free to walk around, sit in the observation carriage for a while and enjoy the scenery out the windows, have a nice meal in the dining car, read a book, or play a board game. In short, the train is all about enjoying the trip, which isn't something I do so much when traveling by airline or by car, when the trip seems more of a mission to get there than an experience to enjoy along the way. Chicago offers much to do for a family. This time, getting there was half the fun.
Answer: Delighted.
[EX A]: Which of the following words best describes the whole family's feeling about the train journey?

[EX Q]: Article: Using too much water or throwing rubbish into our rivers are clear ways that humans can put our water supply in danger , but we also affect our water supply in less obvious ways. You may wonder how paving a road can lead to less useable fresh water. A major part of the water we use every day is groundwater. Groundwater does not come from lakes or rivers. It comes from underground. The more roads and parking lots we pave the less water can flow into the ground to become groundwater. Human activity is not responsible for all water shortages . Drier climates are of course more likely to have droughts than areas with more rainfall, but in any case, good management can help to make sure there is enough water to meet our basic needs. Thinking about the way we use water every day can make a big difference, too In the United States , a family of four can use 1. 5 tons of water a day! This shows how much we depend on water to live, but there's a lot we can do to lower the number. You can take steps to save water in your home. To start with use the same glass for your drinking water all day. Wash it only once a day. Run your dishwasher only when it is full . Help your parents fix any leaks in your home. You can even help to keep our water supply clean by recycling batteries instead of throwing them away.
Answer: Throwing rubbish into lakes.
[EX A]: Which of the following is most likely to lead to less groundwater?

[EX Q]: Article: When was the last time someone did something unexpectedly nice for you? Not someone you knew, but a total stranger? It's happened to me a few times, but two instances really stand out. A few years ago, I was dining out with a person who kept going on and on about himself, completely unaware of the fact that I was sitting there in misery . It wasn't his company that disappointed me. I was recovering from a bad grade in my study. I could have collapsed in tears right there at the table. When we picked up the check, the waitress said, "Your meal was already paid for." My friend and I didn't have a clue how it happened. Then I remembered a man coming in out of the corner of my eye. He was dressed in mostly white, sat down at the bar, had a glass of wine, stayed for maybe ten minutes and then left. The waitress said, "Yes, the gentleman who was in here a while ago paid for you." Just last year, I was running a half-marathon. With just 0.1 miles to go, I was out of gas. Runners call it "hitting the wall"; I thought I couldn't move another muscle. Out of nowhere, a teenager jogged up next to me and said, "What's your name sweetie? Jennifer? Okay, Jennifer, let's go! Come on! It's just around the corner! You can do it!". And he ran with me until I picked up my pace. I found him at the finish line to thank him for the encouragement only to learn he wasn't even supposed to be in the race that day. He was running in place of someone else. I still shake my head when I think of these momentary angels that came to me at my point of need. Do you have any experiences like this?
Answer: Because she was doing poorly in her study.
