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".

Example Input: Einstein and Maric married in January 1903. In May 1904, the couple's first son, Hans Albert Einstein, was born in Bern, Switzerland. Their second son, Eduard, was born in Zurich in July 1910. In 1914, the couple separated; Einstein moved to Berlin and his wife remained in Zurich with their sons. They divorced on 14 February 1919, having lived apart for five years. Eduard, whom his father called "Tete" (for petit), had a breakdown at about age 20 and was diagnosed with schizophrenia. His mother cared for him and he was also committed to asylums for several periods, including full-time after her death. The marriage with Maric does not seem to have been very happy. In letters revealed in 2015, Einstein wrote to his early love, Marie Winteler, about his marriage and his still strong feelings for Marie. In 1910 he wrote to her that "I think of you in heartfelt love every spare minute and am so unhappy as only a man can be" while his wife was pregnant with their second child. Einstein spoke about a "misguided love" and a "missed life" regarding his love for Marie. Einstein married Elsa Lowenthal on 2 June 1919, after having had a relationship with her since 1912. She was a first cousin maternally and a second cousin paternally. In 1933, they emigrated to the United States. In 1935, Elsa Einstein was diagnosed with heart and kidney problems; she died in December 1936. <sep>Who was called "Tete" in the story?<sep>The father
Example Output: No

Example Input: 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
Example Output: No

Example 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>When is this year's Senior Day?<sep>May 16
