instruction:
In this task, you will be presented with a context passage, a question about that paragraph, and a possible answer to that question. The task is to check the validity of the answer. Answer with "Yes" or "No".
question:
Heat supplies the energy that causes motion. The deeper you go into toward the Earths core, the hotter it gets. At the core it is really hot. All that heat tries to rise toward the surface. In the Mantle, the rock is partially melted and is able to move. As it is heated, the material in the mantle moves toward the surface. As the mantle material rises, it cools. When it reaches the Earths crust, it is mostly stopped. A little of the material can break through the surface, but not all. Instead, it begins to move horizontally. The mantle material moves horizontally away from a mid-ocean ridge crest. Toward the surface, the mantle material starts to cool. As it cools it sinks back down into the mantle. These areas are where deep sea trench occur. The material sinks back down to the core. The system operates like a giant conveyor belt. The motion due to heating and cooling is called convection. <sep>Where do sea trenches occur?<sep>Surface
answer:
No

question:
Mechanical energy is a combination of the energy of motion or position. This type of energy describes objects that are moving or could move. A moving ball can have energy from motion. An arrow can also have the energy of motion. Both are types of mechanical energy. Can you think of some other examples? Where does the energy of motion come from? It comes from the energy created by position. This energy is stored energy. This means it is not moving yet, but it has the potential to move. How can you store energy? The arrow gains energy from the drawn bow. As the arrow is released, the bow releases its stored energy and puts the arrow into motion. Can you think of some other ways to store energy using position? <sep>Is an object with mechanical energy always moving?<sep>Yes
answer:
No

question:
I wondered if that were my case--if I rode out for honour, and not for the pure pleasure of the riding. And I marvelled more to see the two of us, both lovers of one lady and eager rivals, burying for the nonce our feuds, and with the same hope serving the same cause. We slept the night at Aird's store, and early the next morning found Ringan. A new Ringan indeed, as unlike the buccaneer I knew as he was unlike the Quaker. He was now the gentleman of Breadalbane, dressed for the part with all the care of an exquisite. He rode a noble roan, in his Spanish belt were stuck silver-hafted pistols, and a long sword swung at his side. When I presented Grey to him, he became at once the cavalier, as precise in his speech and polite in his deportment as any Whitehall courtier. They talked high and disposedly of genteel matters, and you would have thought that that red-haired pirate had lived his life among proud lords and high-heeled ladies. That is ever the way of the Highlander. He alters like a clear pool to every mood of the sky, so that the shallow observer might forget how deep the waters are. <sep>What is the name of the gentleman of Breadalbane?<sep>Ringan
answer:
Yes
