Article: Many other inventions marked Bell's later life, including groundbreaking work in optical telecommunications, hydrofoils and aeronautics. Although Bell was not one of the 33 founders of the National Geographic Society, he had a strong influence on the magazine while serving as the second president from January 7, 1898 until 1903.

Question: What field did Bell later work in, apart from optical telecommunications and aeronautics?
Ans: hydrofoils

Article: After about 1840, Georgian conventions were slowly abandoned as a number of revival styles, including Gothic Revival, that had originated in the Georgian period, developed and contested in Victorian architecture, and in the case of Gothic became better researched, and closer to their originals. Neoclassical architecture remained popular, and was the opponent of Gothic in the Battle of the Styles of the early Victorian period. In the United States the Federalist Style contained many elements of Georgian style, but incorporated revolutionary symbols.

Question: When was the Battle of the Styles contested?
Ans: early Victorian period

Article: Under the provisions of the 1833 India Act, control of Saint Helena was passed from the East India Company to the British Crown, becoming a crown colony. Subsequent administrative cost-cutting triggered the start of a long-term population decline whereby those who could afford to do so tended to leave the island for better opportunities elsewhere. The latter half of the 19th century saw the advent of steam ships not reliant on trade winds, as well as the diversion of Far East trade away from the traditional South Atlantic shipping lanes to a route via the Red Sea (which, prior to the building of the Suez Canal, involved a short overland section). These factors contributed to a decline in the number of ships calling at the island from 1,100 in 1855 to only 288 in 1889.

Question: Who turned over control of Saint Helena to the British Crown?
Ans: East India Company

Article: Genetically modified (GM) cotton was developed to reduce the heavy reliance on pesticides. The bacterium Bacillus thuringiensis (Bt) naturally produces a chemical harmful only to a small fraction of insects, most notably the larvae of moths and butterflies, beetles, and flies, and harmless to other forms of life. The gene coding for Bt toxin has been inserted into cotton, causing cotton, called Bt cotton, to produce this natural insecticide in its tissues. In many regions, the main pests in commercial cotton are lepidopteran larvae, which are killed by the Bt protein in the transgenic cotton they eat. This eliminates the need to use large amounts of broad-spectrum insecticides to kill lepidopteran pests (some of which have developed pyrethroid resistance). This spares natural insect predators in the farm ecology and further contributes to noninsecticide pest management.

Question: What bacterium is used to produced GM cotton?
Ans:
Bacillus thuringiensis
