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: Historically, LSEO letter-writing campaigns generated from $11,000 to $25,000 annually, recalls Dallas Ferguson, a Tulsa attorney and board president of the new LASO. That amount hardly offset enormous cuts, beginning in 1996, by Congress to Legal Services Corp., the chief funding source for state legal-aid agencies. Threatened with extinction, LSEO clawed its way back with the help of state funding, grant money and the Tulsa Area United Way. Meanwhile, the clients keep coming. At least three-quarters are women and children living in poverty. The agency helps more than 12,000 children a year. A third of LSEO's clients are the working poor who receive no government benefits. Many are senior citizens. Riggs regrets that retired Tulsa attorney John Athens, a champion of legal aid, did not live to see how much the money has meant. Athens died last year. In his honor, The Oxley Foundation donated $200,000 to expand a client hot line. That service, which will be expanded statewide, enables needy people to consult an attorney about civil legal problems, including rent and contract disputes, domestic abuse, consumer issues and custody matters. Attorneys handle no criminal cases. R.H. Harbaugh, foundation trustee and a colleague of Athens at the Conner & Winters law firm, said his mentor had "a special interest in people who could not afford legal services. He was aware of the hot line and supported its expansion." Said Riggs: "We use lofty phrases such as 'with justice for all,' when we talk about our legal system. That phrase is etched on our U.S. Supreme Court building. Those are just empty words if people don't have access to that system." <sep>The Oxley Foundation donated $200,000 to expand a client hot line in whose honor?<sep>Riggs
Example Output: No

Example Input: Earthquakes seemed to outline a special feature of earth's crust. Earthquakes let scientists know where the crust was moving. This led to the discovery that the Earths crust was broken up into regions, or plates. Earthquakes happen most often along these plate boundaries. This was evidence that continents can move. The movements of the plates are called plate tectonics. The Earths crust is divided into plates. There are about a dozen large plates and several small ones. Each plate is named for the continent or ocean basin it contains. Scientists know he plates are in motion. They now know the direction and speed of this motion . Plates dont move very fast. They move only a few centimeters a year. This is about the same rate fingernails grow. So you might wonder, what could cause this motion? What supplies the energy to cause this change? <sep>How fast do plates move?<sep>A few centimeters a year
Example Output: Yes

Example Input: The city of Edinburgh grew up around the steep, ragged cliff of the Castle Rock and its easily defended summit. Archaeological excavations have revealed evidence of habitation here as long ago as 900 b.c. Very little, however, is known about the Rock and its inhabitants in the centuries between its first occupation and the time of the MacAlpin kings. A few shadowy details have been left to us by the Romans and by an epic poem from the seventh century. Romans and Britons The Romans invaded Scotland in a.d. 78–84, where they met a fierce group called the Picts, whom they drove north. They consolidated their gains by building Antonine's Wall across the waist of Scotland between the Firth of Forth and the River Clyde in about a.d. Roman legions encountered the strongholds of the Castle Rock and Arthur's Seat, held by a tribe of ancient Britons known as the Votadini. Little is recorded about this group, but they were probably the ancestors of the Gododdin, whose feats are told in a seventh-century Old Welsh manuscript. The capital of the Gododdin was Din Eidyn (the "Fort of Eidyn," almost certainly the Castle Rock), whose name lives on in the Edin- of Edinburgh. Din Eidyn fell to the Angles in 638 and became part of the Anglian kingdom of Northumbria. It was the first of many times that the Fort of Eidyn would change hands between the kingdoms of the north and the south. The MacAlpin Kings Four distinct peoples once inhabited the land now known as Scotland: the Picts in the north, the Britons in the southwest, the invading Angles in the southeast, and the Scots in the west. The Scots were Gaelic-speaking immigrants from the north of Ireland. Kenneth MacAlpin, who ruled as king of Scots at Dunadd, acquired the Pictish throne in 843, uniting Scotland north of the River Forth into a single kingdom. He moved his capital — along with the Stone of Destiny (on which Scottish kings were crowned) — to the sacred Pict site of Scone, close to Perth. His great-great-great-grandson, Malcolm II (1005–1034), defeated the Angles at the Battle of Carham in 1018 and extended Scottish territory as far south as the River Tweed. <sep>Who was Kenneth MacAlpin's great-great-great Grandson?<sep>Malcolm II
Example Output:
Yes
