Brood parasites are organisms—usually birds—that manipulate a host, either of the same or a different species, into raising their young. The parasitic parent avoids the effort of rearing young by abandoning its eggs in the nest of a host bird. After hatching, the parasitic nestlings may kill or crowd out the host's own offspring. The host will often continue to feed and care for the invasive chicks even when they do not resemble its young and may physically dwarf the host itself. Why?

For 27 years after its completion in 1937, the Golden Gate Bridge had the longest main span in the world, stretching 4,200 ft (1,280 m). Its four-year construction, supervised by chief engineer Joseph B. Strauss, faced many difficulties, including rapidly running tides, frequent storms and fogs, and the problem of blasting rock under deep water to plant earthquake-resistant foundations. Considered a modern wonder, the bridge spans the Golden Gate, a strait that links what two bodies of water?

Shah Jahan succeeded to the throne of India's Mughal Empire in 1628 and ruled for 30 years. His reign was notable for its successes against the Deccan states.

Considered the finest example of Mughal architecture, the Taj Mahal was built in memory of his beloved wife. Who deposed and imprisoned him in 1658?
