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: The idea that Earth is a magnet is far from new. It was first proposed in 1600 by a British physician named William Gilbert. Knowing it acts like a magnet is one thing. Knowing why it acts like a magnet is more difficult. In fact, finding out why is a fairly recent discovery. To find out why required new technology. It was the seismograph that made it possible to learn why the Earth acted like a magnet. Seismograph are used to study earthquakes. By studying earthquake waves they were able to learn about Earths interior. They discovered that Earth has an inner and outer core. The outer core consists of liquid metals, mainly iron and nickel. Scientists think that Earths magnetic field is generated here. It is caused by the motion of this liquid metal. The liquid metal moves as Earth spins on its axis. <sep>How does Earth create its magnetism?<sep>Earth has an inner and outer core. consists of liquid metals, mainly iron and nickel.Earths magnetic field is generated here

Output: Yes


Input: Consider Input: How would the universe look without gravity? It would have no planets and no stars. Thats how it looked when it was young. When the universe was young, there was only gas and dust. From this gas and dust, everything we now see was made. How were stars and planets created from just gas and dust? The answer is gravity. The same gravity that holds you down on Earth. The same force that causes your pencil to roll off your desk. The same force that causes it to fall to the floor. The invisible force of gravity caused dust and gas particles to be pulled together. This force is what formed all the objects in our solar system. This force formed the smallest moons. It also formed our Sun. This force caused more than just our solar system to form. It caused all the other solar systems to form. It caused the formation of all the galaxies of the universe. <sep>What does gravity do to the universe?<sep>It forms gas and dust

Output: No


Input: Consider Input: It's just this hard when I try to answer the question: Why do older Oklahomans need lawyers? The answers are important enough that they will be a discussion topic of this year's Senior Day at 9 a.m. March 25 in the House Chamber at the Capitol. The following is a preview of some of the answers for review: We can all agree that older Oklahomans need medical care. But even the best care is worthless if an older patient can't drive to the doctor for ongoing treatment because his or her car has been wrongfully seized in a debt dispute. Therefore, lawyers are part of the prescription for regular medical care for many of the 600,000 Oklahomans age 60 and older. Another example: if a doctor treats an elderly patient for a lung ailment, the doctor's treatment will be undone and he will see the patient again and again, if the patient is sent home to an unheated apartment. Lawyers know how to make landlords heat apartments so the medical treatment can stick. (By the way, a May 16, 2001, article in The New York Times reports on a program at Boston Medical Center providing a walk-in legal clinic in the hospital to help fight their patients' legal and administrative battles.) We also can agree that older Oklahomans - like all citizens - have rights to control their health care until they become incapacitated or these rights are transferred to another by legal document or process. "Old" is not a legal classification that results in automatic loss of these rights. Moreover, having an old parent does not automatically confer on children the right to make the parents' health care choices. It follows that an important role lawyers provide for aging Oklahomans is not only to create rights - transferring documents such as durable powers of attorney and guardianship orders, but also to monitor their use. In family situations, for example, lawyers must ensure that powers of attorney and guardianships are used to serve only the person transferring or losing rights. They are not to be used to help a family "manage" their mother or help a doctor or nursing home get permission for a pill or procedure they feel is in the best interest of a patient. Good news: Oklahoma now has a Public Guardianship Program, albeit unfunded, that will supply lawyers to perform this rights-monitoring process Oklahoma grandparents should be able to enjoy their grandchildren, not raise them. But owing to the social problems of divorce and drug use, grandparents are increasingly being called on to raise their grandchildren because of missing parents. Adding to the physical, emotional and financial burden they take on, grandparents face legal problems. All the decisions parents made without a second thought now require evidence of legal authority when made by grandparents. <sep>What can lawyers do for old people?<sep>They can get prescriptions for them


Output: No
