You are given a background paragraph that describes one or more causal or qualitative relationships such as a relationship in economics or a scientific law and a story that makes use of the concepts or the relationship described in the provided paragraph. You are also given a question about the story that requires an understanding of the relationship described in the background paragraph and the story. You need to come up with an answer to the given question; the answer will be a span from either the question or the story. In order to correctly answer the given question, you need to understand the relationship mentioned in the background paragraph and should be able to use it to understand that in the story. Your answer can not consist of any word that is not mentioned in any of these: the background paragraph, the story, or the question. You can directly copy and paste a span from the story or the question while answering the given question.

Background Paragraph: About 10% of sedimentary rocks are limestones. The solubility of limestone in water and weak acid solutions leads to karst landscapes, in which water erodes the limestone over thousands to millions of years. Most cave systems are through limestone bedrock. 
Story: White mountains are often visited by tourists because of the many beautiful caves, stalactites, stalagmites and karst phenomena. Dome mountains are interesting to tourists because they are very massive, of volcanic origin and excellent for climbing. 
Question: Which mountain is made of less soluble rock?
Dome.

Background Paragraph: Regions on the Earth's surface (or in its atmosphere) that are high above mean sea level are referred to as high altitude. High altitude is sometimes defined to begin at 2,400 meters (8,000 ft) above sea level.[5][6][7]

At high altitude, atmospheric pressure is lower than that at sea level. This is due to two competing physical effects: gravity, which causes the air to be as close as possible to the ground; and the heat content of the air, which causes the molecules to bounce off each other and expand.[8]. 
Story: There was a competition for who can get the model plane highest into the air. Team 1 got it 1,000 ft. Team 2 got it 2,000 ft. Team 3 go it 4,000 ft. Team 4 got it 9,000 ft. Team 5 got it 10,000 ft. Team 6 got it 12,000 ft. Team 7 got it 13000 ft. Team 7 won the contest and got a gold trophy as the prize. 
Question: What team got their kite into high altitude: Team 1 or Team 5?
Team 5.

Background Paragraph: The sloping surface of the inclined plane supports part of the weight of the object as it moves up the slope. As a result, it takes less force to move the object uphill. The trade-off is that the object must be moved over a greater distance than if it were moved straight up to the higher elevation. On the other hand, the output force is greater than the input force because it is applied over a shorter distance. Like other simple machines, the ideal mechanical advantage of an inclined plane is given by. 
Story: Adams needs to roll a piano into his new house. The piano is very heavy and unfortunately he isn't strong enough to lift it up his front steps.  A friend of his suggests he get a ramp since it will support part of the weight allowing him to push it into his house much easier. Adam gets the ramp and successfully pushes the piano in to his new house. 
Question: Will Adam have an easier time lifting a heavy refrigerator into his new house or pushing it up a ramp?

pushing.
