PROBLEM: A PT boat ( short for Patrol Torpedo boat ) was a torpedo - armed fast attack craft used by the United States Navy in World War II .

PROBLEM: 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 . In practice , the Wall served to prevent the massive emigration and defection that had marked East Germany and the communist Eastern Bloc during the post-World War II period .

SOLUTION: Berlin Wall

PROBLEM: The Lion Capital of Ashoka is a sculpture of four Asiatic lions standing back to back , on an elaborate base that includes other animals . A graphic representation of it was adopted as the official Emblem of India in 1950 . It was originally placed atop the Aśoka pillar at the important Buddhist site of Sarnath by the Emperor Ashoka , in about 250 BCE . The pillar , sometimes called the Aśoka Column , is still in its original location , but the Lion Capital is now in the Sarnath Museum , in the state of Uttar Pradesh , India . Standing 2.15 metres ( 7 feet ) high including the base , it is more elaborate than the other very similar surviving capitals of the pillars of Ashoka bearing the Edicts of Ashoka that were placed throughout India several of which feature single animals at the top ; one other damaged group of four lions survives , at Sanchi .

SOLUTION:
Lion Capital of Ashoka
