QUES: In the 1960s, Downtown Houston consisted of a collection of mid-rise office structures. Downtown was on the threshold of an energy industry–led boom in 1970. A succession of skyscrapers were built throughout the 1970s—many by real estate developer Gerald D. Hines—culminating with Houston's tallest skyscraper, the 75-floor, 1,002-foot (305 m)-tall JPMorgan Chase Tower (formerly the Texas Commerce Tower), completed in 1982. It is the tallest structure in Texas, 15th tallest building in the United States, and the 85th tallest skyscraper in the world, based on highest architectural feature. In 1983, the 71-floor, 992-foot (302 m)-tall Wells Fargo Plaza (formerly Allied Bank Plaza) was completed, becoming the second-tallest building in Houston and Texas. Based on highest architectural feature, it is the 17th tallest in the United States and the 95th tallest in the world. In 2007, downtown Houston had over 43 million square feet (4,000,000 m²) of office space.

QUES: Georgian succeeded the English Baroque of Sir Christopher Wren, Sir John Vanbrugh, Thomas Archer, William Talman, and Nicholas Hawksmoor; this in fact continued into at least the 1720s, overlapping with a more restrained Georgian style. The architect James Gibbs was a transitional figure, his earlier buildings are Baroque, reflecting the time he spent in Rome in the early 18th century, but he adjusted his style after 1720. Major architects to promote the change in direction from baroque were Colen Campbell, author of the influential book Vitruvius Britannicus (1715-1725); Richard Boyle, 3rd Earl of Burlington and his protégé William Kent; Isaac Ware; Henry Flitcroft and the Venetian Giacomo Leoni, who spent most of his career in England. Other prominent architects of the early Georgian period include James Paine, Robert Taylor, and John Wood, the Elder. The European Grand Tour became very common for wealthy patrons in the period, and Italian influence remained dominant, though at the start of the period Hanover Square, Westminster (1713 on), developed and occupied by Whig supporters of the new dynasty, seems to have deliberately adopted German stylisic elements in their honour, especially vertical bands connecting the windows.

What became very popular with wealthy patrons during this period?
What is the answer?
ANS: The European Grand Tour
QUES: A squab is the name given to the young of domestic pigeons that are destined for the table. Like other domesticated pigeons, birds used for this purpose are descended from the rock pigeon (Columba livia). Special utility breeds with desirable characteristics are used. Two eggs are laid and incubated for about 17 days. When they hatch, the squabs are fed by both parents on "pigeon's milk", a thick secretion high in protein produced by the crop. Squabs grow rapidly, but are slow to fledge and are ready to leave the nest at 26 to 30 days weighing about 500 g (18 oz). By this time, the adult pigeons will have laid and be incubating another pair of eggs and a prolific pair should produce two squabs every four weeks during a breeding season lasting several months.

Why does the breeding season only last a few days?
