F. Dostoyevsky's Memorial Apartment is the only museum in Moscow and the first in the world.

False. The text states it is the only museum in Moscow, but does not claim it is the first in the world. It also mentions that Fyodor Mikhailovich spent the first fifteen years of his life there, which was when his character took shape. The museum occupies a wing of Mariinskaya hospital. Although Fyodor was born in the opposite wing in 1821, he lived with his parents in the apartment (now the museum) from 1823 to 1837.
