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: Sometimes a full Moon moves through Earths shadow. This is a lunar eclipse . During a total lunar eclipse, the Moon travels completely in Earths umbra. During a partial lunar eclipse, only a portion of the Moon enters Earths umbra. When the Moon passes through Earths penumbra, it is a penumbral eclipse. Since Earths shadow is large, a lunar eclipse lasts for hours. Anyone with a view of the Moon can see a lunar eclipse. So unlike a solar eclipse, it doesnt get dark on Earth. Instead it gets dark on the Moon. Partial lunar eclipses occur at least twice a year, but total lunar eclipses are less common. The Moon glows with a dull red coloring during a total lunar eclipse. <sep>During a lunar eclipse, does the earth or moon get dark?<sep>It doesnt get dark on Earth
Example Output: No

Example Input:  Bin Laden reportedly discussed the planes operation with KSM and Atef in a series of meetings in the spring of 1999 at the al Matar complex near Kandahar. KSM's original concept of using one of the hijacked planes to make a media statement was scrapped, but  Bin Laden considered the basic idea feasible.  Bin Laden, Atef, and KSM developed an initial list of targets. These included the White House, the U.S. Capitol, the Pentagon, and the World Trade Center. According to KSM,  Bin Laden wanted to destroy the White House and the Pentagon, KSM wanted to strike the World Trade Center, and all of them wanted to hit the Capitol. No one else was involved in the initial selection of targets.  Bin Laden also soon selected four individuals to serve as suicide operatives: Khalid al Mihdhar, Nawaf al Hazmi, Khallad, and Abu Bara al Yemeni. During the al Matar meetings,  Bin Laden told KSM that Mihdhar and Hazmi were so eager to participate in an operation against the United States that they had already obtained U.S. visas. KSM states that they had done so on their own after the suicide of their friend Azzam (Nashiri's cousin) in carrying out the Nairobi bombing. KSM had not met them. His only guidance from  Bin Laden was that the two should eventually go to the United States for pilot training. Hazmi and Mihdhar were Saudi nationals, born in Mecca. Like the others in this initial group of selectees, they were already experienced mujahideen. They had traveled together to fight in Bosnia in a group that journeyed to the Balkans in 1995. By the time Hazmi and Mihdhar were assigned to the planes operation in early 1999, they had visited Afghanistan on several occasions. Khallad was another veteran mujahid, like much of his family. His father had been expelled from Yemen because of his extremist views. Khallad had grown up in Saudi Arabia, where his father knew  Bin Laden, Abdullah Azzam, and Omar Abdel Rahman (the "Blind Sheikh"). <sep>How many people were involved in selecting targets to destroy by plane?<sep>2
Example Output: Yes

Example Input: Hurlburt Field, Florida (CNN) -- An Air Force CV-22 Osprey crashed Wednesday during a routine training mission north of Navarre, Florida, injuring five crew members aboard, a military official said. The crash occurred about 6:45 p.m. at Hurlburt Field's Eglin Range, said Amy Nicholson, chief of public affairs at the airfield. The five injured crew members were taken to an area hospital, Nicholson said. The extent of their injuries was not immediately known. The cause of the accident is under investigation, she said. The Osprey was assigned to the 1st Special Operations Wing, the Air Force said. The tilt-rotor aircraft can fly like an airplane and land like a helicopter. The Army began developing the Osprey in 1982, though the program was nearly scrapped in 1989 when then-Secretary of Defense Dick Cheney sought to cancel it because of ballooning costs. Questions were raised about the safety of the Osprey after two crashes, including one in 1992 at a Marine Corps air base in Virginia that killed the crew. In late 2000, the Marine Corps grounded the Osprey fleet after two crashes -- one in Arizona that killed four crew members and 15 passengers, and another in North Carolina that killed the crew. A redesign was ordered on the Osprey, and it resumed flights in 2002. The Air Force began using Ospreys in 2008 after testing the aircraft in 2006. They were first deployed by the Marines in Iraq in 2007 after 18 years and $20 billion in development. <sep>When was the CV-22 budget called into question and what is the overall development total?<sep>1992
Example Output:
No
