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".

Input: Consider Input: You know that friction also causes heat. Think about when you rub your hands together. It is friction that makes them warm. But why does this happen? Friction causes the molecules on rubbing surfaces to move faster. Faster moving particles have more heat energy. Heat from friction can be useful. Can you think of other places where you might find friction? Friction also lets you light a match. Heat from friction can also cause problems. It can cause a car to overheat. To reduce friction, oil is added to the engine. Oil coats the surfaces of moving parts. This coating of oil makes them slippery. When things are slippery there is less friction. Have you ever seen a sign that says, slippery when wet? This too has to do with friction. Water, like oil, can reduce friction. The wet surface may allow your shoes to slide more easily. <sep>What can be done to prevent friction problems in engines?<sep>Oil is added to the engine

Output: Yes


Input: Consider Input: Earths magnetic field helps protect Earth and its organisms. It protects us from harmful particles given off by the sun. Most of the particles are attracted to the north and south magnetic poles. This is where Earths magnetic field is strongest. This is also where relatively few organisms live. Another benefit of Earths magnetic field is its use for navigation. People use compasses to detect Earths magnetic north pole. Knowing this helps them tell direction. Many animals have natural 'compasses' that work just as well. Birds like the garden warbler in Figure 1.36 use Earths magnetic field. They use it to guide their annual migrations. Recent research suggests that warblers and other migrating birds have structures in their eyes. These structures let them see Earths magnetic field as a visual pattern. <sep>Where is the structure located, that warblers use to detect the magnetic fields of Earth?<sep>Pancreas

Output: No


Input: Consider Input: Rakal, her first officer, was staring pensively at his panel. He was what this was all about. She watched his graceful fingers ending in thick black claws tap out calculations on the panel. His pointed ears swiveled back and forth, catching every sound from the bridge, while his long tail swished to the rhythm of his thoughts. Only those of the Arrallin Insurrection inner team knew he was no common 'beta furry'. His silken fur, which would be tawny golden and striped with jet black bands, was dyed perfectly to a pure black, and his mane trimmed and thinned as to be indistinguishable from the rest of his coat. His eyes had been treated and darkened to a rich purple to disguise the brilliant golden yellow color that would mark him as an Alpha Arrallin, and leader of his hive. Right now, he looked like an overgrown wolf who'd learned touch-typing. The scout ship re-emerged from the hole - a brilliant speck emerging from a sphere of velvety blackness. It's hail crackled across the comm, and Tara spun to retake her seat at the helm. "Launch the second probe. Won't Central be crushed to learn that another gateway has yielded little more than a class F planet and a white dwarf system. Level 1 and 2 staffers should prepare to be briefed and move out. This sounds like it's the one." The distinctive whuffle of pleasure rippled through the betas on the bridge, and Rakal let loose a small growl, as if to caution his charges against false hope. They'd scouted twenty-seven gates so far, and none had turned up anything worth the Insurrection's time. Tara would not let giddy hopes drag them onto a rock that would spell the end for the project, and the Arrallin species. <sep>What was the mission all about?<sep>To escape from the terror of a poor dictator


Output: No
