[EX Q]: 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.

[EX Q]: Monoamniotic twins are identical twins that share the same amniotic sac within their mother's uterus. Monoamniotic twins are always identical, always monochorionic and are usually termed Monoamniotic-Monochorionic (``MoMo'' or ``Mono Mono'') twins. They also share the placenta, but have two separate umbilical cords. Monoamniotic twins develop when an embryo does not split until after formation of the amniotic sac, at about 9-13 days after fertilization. Monoamniotic triplets or other monoamniotic multiples are possible, but extremely rare. Other obscure possibilities include multiples sets where monoamniotic twins are part of a larger gestation such as triplets, quadruplets, or more.
