Question: Once regarded as plants constituting the class Schizomycetes, bacteria are now classified as prokaryotes. Unlike cells of animals and other eukaryotes, bacterial cells do not contain a nucleus and rarely harbour membrane-bound organelles. Although the term bacteria traditionally included all prokaryotes, the scientific classification changed after the discovery in the 1990s that prokaryotes consist of two very different groups of organisms that evolved from an ancient common ancestor. These evolutionary domains are called Bacteria and Archaea.
Is there an answer to this question: What are two main groups prokaryotes can be divided into?

Answer: Bacteria and Archaea

Question: Meteorites from Antarctica are an important area of study of material formed early in the solar system; most are thought to come from asteroids, but some may have originated on larger planets. The first meteorite was found in 1912, and named the Adelie Land meteorite. In 1969, a Japanese expedition discovered nine meteorites. Most of these meteorites have fallen onto the ice sheet in the last million years. Motion of the ice sheet tends to concentrate the meteorites at blocking locations such as mountain ranges, with wind erosion bringing them to the surface after centuries beneath accumulated snowfall. Compared with meteorites collected in more temperate regions on Earth, the Antarctic meteorites are well-preserved.
Is there an answer to this question: What is it about Antarctic meteorites that is different form meteorites found in other places?

Answer: well-preserved.

Question: The Saint Helena Constitution took effect in 1989 and provided that the island would be governed by a Governor and Commander-in-Chief, and an elected Executive and Legislative Council. In 2002, the British Overseas Territories Act 2002 granted full British citizenship to the islanders, and renamed the Dependent Territories (including Saint Helena) the British Overseas Territories. In 2009, Saint Helena and its two territories received equal status under a new constitution, and the British Overseas Territory was renamed Saint Helena, Ascension and Tristan da Cunha.
Is there an answer to this question: In 2002 what act granted full British citizenship to the citizens of the islands?

Answer: British Overseas Territories Act 2002

Question: The advent of the Industrial Revolution in Britain provided a great boost to cotton manufacture, as textiles emerged as Britain's leading export. In 1738, Lewis Paul and John Wyatt, of Birmingham, England, patented the roller spinning machine, as well as the flyer-and-bobbin system for drawing cotton to a more even thickness using two sets of rollers that traveled at different speeds. Later, the invention of the James Hargreaves' spinning jenny in 1764, Richard Arkwright's spinning frame in 1769 and Samuel Crompton's spinning mule in 1775 enabled British spinners to produce cotton yarn at much higher rates. From the late 18th century on, the British city of Manchester acquired the nickname "Cottonopolis" due to the cotton industry's omnipresence within the city, and Manchester's role as the heart of the global cotton trade.
Is there an answer to this question: What event produced an expansion of John Wyatt's cotton industry?

Answer:
