Article: Li Zicheng then led a coalition of rebel forces numbering 200,000[a] to confront Wu Sangui, the general commanding the Ming garrison at Shanhai Pass. Shanhai Pass is a pivotal pass of the Great Wall, located fifty miles northeast of Beijing, and for years its defenses kept the Manchus from directly raiding the Ming capital. Wu Sangui, caught between a rebel army twice his size and a foreign enemy he had fought for years, decided to cast his lot with the Manchus, with whom he was familiar. Wu Sangui may have been influenced by Li Zicheng's mistreatment of his family and other wealthy and cultured officials; it was said that Li also took Wu's concubine Chen Yuanyuan for himself. Wu and Dorgon allied in the name of avenging the death of the Chongzhen Emperor. Together, the two former enemies met and defeated Li Zicheng's rebel forces in battle on May 27, 1644.

Question: How big was Li Zicheng's army?
Ans: 200,000

Article: The period saw the growth of a distinct and trained architectural profession; before the mid-century "the high-sounding title, 'architect' was adopted by anyone who could get away with it". But most buildings were still designed by builders and landlords together, and the wide spread of Georgian architecture, and the Georgian styles of design more generally, came from dissemination through pattern books and inexpensive suites of engravings. This contrasted with earlier styles, which were primarily disseminated among craftsmen through the direct experience of the apprenticeship system. Authors such as the prolific William Halfpenny (active 17231755) received editions in America as well as Britain. From the mid-18th century, Georgian styles were assimilated into an architectural vernacular that became part and parcel of the training of every architect, designer, builder, carpenter, mason and plasterer, from Edinburgh to Maryland.

Question: How did most Georgian design styles disseminate?
Ans: pattern books and inexpensive suites of engravings

Article: Neolithic peoples in the Levant, Anatolia, Syria, northern Mesopotamia and Central Asia were also accomplished builders, utilizing mud-brick to construct houses and villages. At Catal hoyuk, houses were plastered and painted with elaborate scenes of humans and animals. In Europe, long houses built from wattle and daub were constructed. Elaborate tombs were built for the dead. These tombs are particularly numerous in Ireland, where there are many thousand still in existence. Neolithic people in the British Isles built long barrows and chamber tombs for their dead and causewayed camps, henges, flint mines and cursus monuments. It was also important to figure out ways of preserving food for future months, such as fashioning relatively airtight containers, and using substances like salt as preservatives.

Question: What types of sites were built for the deceased?
Ans: Elaborate tombs

Article: Except for a few primitive organisms such as sponges (which have no nervous system) and cnidarians (which have a nervous system consisting of a diffuse nerve net), all living multicellular animals are bilaterians, meaning animals with a bilaterally symmetric body shape (that is, left and right sides that are approximate mirror images of each other). All bilaterians are thought to have descended from a common ancestor that appeared early in the Cambrian period, 485-540 million years ago, and it has been hypothesized that this common ancestor had the shape of a simple tubeworm with a segmented body. At a schematic level, that basic worm-shape continues to be reflected in the body and nervous system architecture of all modern bilaterians, including vertebrates. The fundamental bilateral body form is a tube with a hollow gut cavity running from the mouth to the anus, and a nerve cord with an enlargement (a ganglion) for each body segment, with an especially large ganglion at the front, called the brain. The brain is small and simple in some species, such as nematode worms; in other species, including vertebrates, it is the most complex organ in the body. Some types of worms, such as leeches, also have an enlarged ganglion at the back end of the nerve cord, known as a "tail brain".

Question: Creatures that have a diffuse nerve net are called what?
Ans:
cnidarians
