Q: Read the following article and answer the question. Article: Scientists studying the impact of climate change on the Arctic need to consider ways to reduce their own carbon footprints , says Ryan Brook, a researcher who regularly flies north to study the health of caribous .He calls on scientists to show leadership by examining and sharing ways to reduce the impact of working in polar regions. "The importance of the research is not at question here. It is important to our understanding of and adapting to climate change. But we need to think about better approaches," says Brook. "This is an issue for all scientists, though polar researchers often travel particularly long distances using commercial air travel. We also rely extensively on small aircraft, icebreakers, and snowmobiles, all of which produce large amounts of carbon." Brook studies the health of caribou herds in Nunavut and Northwest Territories. He works with northern wildlife managers. This work typically takes him north five or six times per year and when he calculated his own carbon footprint, he was not happy with the result. "My research footprints are about the same as the annual footprints of an average Toronto resident. Basically, I have two footprints -- my own personal life, which is moderate, and my research footprint." Climate scientists can rightly argue that Arctic research is a specialized field and the community of scientists who travel north is relatively small. Even if all scientists working in the north reduced their carbon emissions, it would not make a big impact on the global scale. For Brook, it's the option that matters. There are ways researchers can reduce the amount of carbon they use. Some helicopters use less fuel than others. Solar and wind power are alternatives to gas-fired generators. And while carbon offsets don't reduce the amount of carbon emitted, they are an easy first step. "There aren't necessarily any easy answers, but we need to start talking about it," says Brook. "This is particularly important for the next generation of scientists being trained and I hope to see... Question: What's the main idea of the text? Answer: | OPTIONS:
- The importance of arctic research is not at question.
- Climate change becomes worse because of arctic research.
- Brook suggests ways of reducing the use of carbon.
- Scientists must look at their own carbon footprints.
A: Scientists must look at their own carbon footprints.

Q: Read the following article and answer the question. Article: Dear Lee, As I told you, I'll be gone until Wednesday morning. Thank you so much for taking on my "children" while I'm away. Like real children, they can be kind of irritating sometimes, but I'm going to enjoy myself so much more knowing they're getting some kind human attention. Remember that Regina (the "queen" in Latin, and she acts like one) is teething. If you don't watch her, she'll chew anything, including her sister, the cat. There are plenty of chew toys around the house. Whenever she starts gnawing on anything illegal, just give her one of those. She generally settles right down to a good hour-long chew. Then you'll see her wandering around whimpering with the remains of the toy in her mouth. She gets really frustrated because what she wants is to bury the thing. She'll try to dig a hole between the cushions of the couch. Finding that unsatisfactory, she'll wander some more, discontent, until you solve her problem for her. I usually show her the laundry basket, moving a few clothes so she can bury her toy beneath them. I do sound like a parent, don't I? You have to understand, my own son is practically grown up. Regina's food is the Puppy Chow in the utility room, where the other pet food is stored. Give her a bowl once in the morning and once in the evening. No more than that, no matter how much she begs. Beagles are notorious overeaters, according to her breeder, and I don't want her to lose her girlish figure. She can share Rex (the King's) water, but be sure it's changed daily. She needs to go out several times a day, especially last thing at night and first thing in the morning. Let her stay out for about ten minutes each time, so she can do all her business. She also needs a walk in the afternoon, after which it's important to romp with her for a while in the yard. The game she loves most is fetch, but be sure to make her drop the ball. She'd rather play tug of war with it. Tell her, "Sit!" Then, when she does, say, "Drop it!" Be sure to tell her "good girl," and then throw the ball for her.... Question: If the sitter is to follow the owner's directions in playing fetch with Regina, at what point will he or she tell Regina "good girl"? Answer: | OPTIONS:
- Every time Regina goes after the ball.
- After Regina finds the ball.
- When Regina brings the ball back.
- After Regina drops the ball.
A: After Regina drops the ball.

Q: Read the following article and answer the question. Article: I arrived at my mother's home for our Monday family dinner. The smells of food flew over from the kitchen. Mother was pulling out quilt after quilt from the boxes, proudly showing me their beauties. She was preparing for a quilt show at the Elmhurst Church. When we began to fold and put them back into the boxes, I noticed something at the bottom of one box. I pulled it out. "What is this?" I asked. "Oh?" Mom said, "That's Mama's quilt." I spread the quilt. It looked as if a group of school children had pieced it together; irregular designs, childish pictures, a _ line on the right. "Grandmother made this?" I said, surprised. My grandmother was a master at making quilts. This certainly didn't look like any of the quilts she had made. "Yes, right before she died. I brought it home with me last year and made some changes," she said. "I'm still working on it. See, this is what I've done so far." I looked at it more closely. She had made straight a crooked line. At the center of the quilt, she had stitched a piece of cloth with these words:"My mother made many quilts. She didn't get all lines straight. But I think this is beautiful. I want to see it finished. Her last quilt." "Oh, this is so nice, Mom," I said. It occurred to me that by completing my grandmother's quilt, my mother was honoring her own mother. I realized, too, that I held in my hands a family treasure. It started with the loving hands of one woman, and continued with the loving hands of another. Question: Why did the author go to mother's home? Answer: | OPTIONS:
- To see her mother's quilts.
- To help prepare for a show.
- To get together for the family dinner.
- To discuss her grandmother's life.
A: To get together for the family dinner.
