input question: Extract the answer to the question from the following context. Question: If a goose were feeling tired in the sky, how would it want to avoid traveling? Context: Many, if not most, birds migrate in flocks. For larger birds, flying in flocks reduces the energy cost. Geese in a V-formation may conserve 1220% of the energy they would need to fly alone. Red knots Calidris canutus and dunlins Calidris alpina were found in radar studies to fly 5 km/h (3.1 mph) faster in flocks than when they were flying alone.???
output answer: fly alone

input question: Extract the answer to the question from the following context. Question: What can authorities look for during a Terry stop? Context: In Terry v. Ohio (1968) the court divided seizure into two parts, the investigatory stop and arrest. The court further held that during an investigatory stop a police officer's search " [is] confined to what [is] minimally necessary to determine whether [a suspect] is armed, and the intrusion, which [is] made for the sole purpose of protecting himself and others nearby, [is] confined to ascertaining the presence of weapons" (U.S. Supreme Court). Before Terry, every police encounter constituted an arrest, giving the police officer the full range of search authority. Search authority during a Terry stop (investigatory stop) is limited to weapons only.???

input question: Extract the answer to the question from the following context. Question: When did the segregation of lodges end? Context: Widespread segregation in 19th- and early 20th-century North America made it difficult for African-Americans to join Lodges outside of Prince Hall jurisdictions and impossible for inter-jurisdiction recognition between the parallel U.S. Masonic authorities. By the 1980s, such discrimination was a thing of the past, and today most U.S. Grand Lodges recognise their Prince Hall counterparts, and the authorities of both traditions are working towards full recognition. The United Grand Lodge of England has no problem with recognising Prince Hall Grand Lodges. While celebrating their heritage as lodges of black Americans, Prince Hall is open to all men regardless of race or religion.???
