[Q]: Passage: Mariana Trench -- Four descents have been achieved. The first was the manned descent by Swiss-designed, Italian-built, United States Navy-owned bathyscaphe Trieste which reached the bottom at 1:06 pm on 23 January 1960, with Don Walsh and Jacques Piccard on board. Iron shot was used for ballast, with gasoline for buoyancy. The onboard systems indicated a depth of 11,521 m (37,799 ft), but this was later revised to 10,916 m (35,814 ft). The depth was estimated from a conversion of pressure measured and calculations based on the water density from sea surface to seabed.

[Q]: Passage: Dulce de leche -- The dulce de leche of El Salvador has a soft, crumbly texture, with an almost crystallized form. Central Mexico had versions as manjar (vanilla flavored) or cajeta, which is made from goat's milk, while in the North of the country the ''dulce de leche'' from cow's milk is more common. In Cuba, dulce de leche is made from soured milk that's curdled and then sweetened, called cortada.
