Example Input: What causes a change in motion? The application of a force. Any time an object changes motion, a force has been applied. In what ways can this happen? Force can cause an object at rest to start moving. Forces can cause objects to speed up or slow down. Forces can cause a moving object to stop. Forces can also cause a change in direction. In short, forces cause changes in motion. The moving object may change its speed, its direction, or both. We know that changes in motion require a force. We know that the size of the force determines the change in motion. How much an objects motion changes when a force is applied depends on two things. It depends on the strength of the force. It also depends on the objects mass. Think about some simple tasks you may regularly do. You may pick up a baseball. This requires only a very small force. <sep>Does an object's mass has very little to do affect how much its motion changes when a force is applied to it?<sep>No
Example Output: No

Example Input:  We were cornered in a sort of way already.  But these butchers up the cavern had been surprised, they were probably scared, and they had no special weapons, only those little hatchets of theirs.  And that way lay escape.  Their sturdy little forms--ever so much shorter and thicker than the mooncalf herds--were scattered up the slope in a way that was eloquent of indecision.  I had the moral advantage of a mad bull in a street.  But for all that, there seemed a tremendous crowd of them.  Very probably there was.  Those Selenites down the cleft had certainly some infernally long spears.  It might be they had other surprises for us.... But, confound it!  if we charged up the cave we should let them up behind us, and if we didn't those little brutes up the cave would probably get reinforced.  Heaven alone knew what tremendous engines of warfare--guns, bombs, terrestrial torpedoes--this unknown world below our feet, this vaster world of which we had only pricked the outer cuticle, might not presently send up to our destruction.  It became clear the only thing to do was to charge!  It became clearer as the legs of a number of fresh Selenites appeared running down the cavern towards us. <sep>Where are the Selenites in relation to the narrator?<sep>Beneath
Example Output: No

Example Input: Powell contended that it was not inconsistent to want to foster cooperation even with an organization like the Indonesian military, which has a history of human rights abuses. "If you get young officers, expose them to a military organization that is within a democratic political institution, such as the United States, then that rubs off on them," he said. In Malaysia, Powell met with Prime Minister Mahathir Mohamad, who has led the country since 1981. The Malaysian foreign minister, Syed Hamid Albar, later told local reporters that Powell had proposed that American and Malaysian officials review the idea of forming a regional training center in Malaysia to coordinate antiterrorism activities. His brief stop in Malaysia also highlighted the moral ambiguities of the effort to prevent terrorism and its emphasis on cooperation with governments that the United States has often criticized. The United States once distanced itself from Mahathir for strong-arm tactics with political rivals, and human rights groups criticize him for arresting and jailing scores of suspected militants, including some who may be linked to al-Qaida, without trial. Powell said his discussions with Mahathir "touched on the case" of his former deputy, Anwar Ibrahim, who is serving a 15-year sentence on charges of sodomy and abuse of power after trials that Powell said the United States had "always felt" were flawed. The assistant secretary of state for East Asian and Pacific affairs, James Kelly, met on Tuesday morning with Anwar's wife, Wan Azizah Wan Ismail, for what she later told Malaysian reporters was a discussion about both the detention of her husband and six supporters, and the campaign against terrorism. <sep>What was the purpose of Powell's trip to Malaysia?<sep>To meet  Wan Azizah Wan Ismail,
