Example Input: The Berlin Wall (German: Berliner Mauer, pronounced (bɛʁˈliːnɐ ˈmaʊ̯ɐ) ( listen)) was a guarded concrete barrier that physically and ideologically divided Berlin from 1961 to 1989. Constructed by the German Democratic Republic (GDR, East Germany), starting on 13 August 1961, the Wall cut off (by land) West Berlin from virtually all of surrounding East Germany and East Berlin until government officials opened it in November 1989. Its demolition officially began on 13 June 1990 and finished in 1992. The barrier included guard towers placed along large concrete walls, accompanied by a wide area (later known as the ``death strip'') that contained anti-vehicle trenches, ``fakir beds'' and other defenses. The Eastern Bloc portrayed the Wall as protecting its population from fascist elements conspiring to prevent the ``will of the people'' in building a socialist state in East Germany.
Example Output: did the berlin wall go all around west berlin?

Example Input: Foods that are claimed to be negative in calories are mostly low-calorie fruits and vegetables such as celery, grapefruit, lemon, lime, apple, lettuce, broccoli, and cabbage. There is no scientific evidence to show that any of these foods have a negative calorific impact. Celery has a thermic effect of around 8%, much less than the 100% or more required for a food to have ``negative calories''. A stalk of celery provides 6 calories to the body, but the body expends only half of a calorie digesting it. Even proteins, which require the most energy to digest, have a thermic energy of only 20%--30%.
Example Output: does it really take more calories to digest celery?

Example Input: Flashbacks reveal that his wife (Salli Richardson) and daughter (Willow Smith) died in a helicopter accident during the chaotic evacuation of Manhattan, prior to the military-enforced quarantine of the island in 2009, when Neville stayed behind on the island as military personnel. Neville's only mitigation for his loneliness is his German Shepherd named Samantha, a.k.a. Sam (given to him by his daughter as a puppy to protect him before she died in the helicopter crash), interaction with mannequins he has set up as patrons at a video store, and recordings of old television broadcasts. At night, he barricades himself and Sam inside his heavily fortified Washington Square Park home to hide from the Darkseekers. One day, while waiting for survivors, Sam follows a deer into a dark building. Neville cautiously goes in after her and finds the deer's corpse along with Sam, but the building is infested by a colony of Darkseekers. Both manage to escape unharmed and the attacking Darkseekers are killed by the sunlight.
Example Output:
did willow smith play in i am legend?
