It is in the great churches and cathedrals and in a number of civic buildings that the Gothic style was expressed most powerfully, its characteristics lending themselves to appeals to the emotions, whether springing from faith or from civic pride. A great number of ecclesiastical buildings remain from this period, of which even the smallest are often structures of architectural distinction while many of the larger churches are considered priceless works of art and are listed with UNESCO as World Heritage Sites. For this reason a study of Gothic architecture is largely a study of cathedrals and churches.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Why are larger cathedrals and churches associated with the Gothic style?
Ah, so.. larger churches are considered priceless works of art

The era of manufactured fibers began with the development of rayon in France in the 1890s. Rayon is derived from a natural cellulose and cannot be considered synthetic, but requires extensive processing in a manufacturing process, and led the less expensive replacement of more naturally derived materials. A succession of new synthetic fibers were introduced by the chemicals industry in the following decades. Acetate in fiber form was developed in 1924. Nylon, the first fiber synthesized entirely from petrochemicals, was introduced as a sewing thread by DuPont in 1936, followed by DuPont's acrylic in 1944. Some garments were created from fabrics based on these fibers, such as women's hosiery from nylon, but it was not until the introduction of polyester into the fiber marketplace in the early 1950s that the market for cotton came under threat. The rapid uptake of polyester garments in the 1960s caused economic hardship in cotton-exporting economies, especially in Central American countries, such as Nicaragua, where cotton production had boomed tenfold between 1950 and 1965 with the advent of cheap chemical pesticides. Cotton production recovered in the 1970s, but crashed to pre-1960 levels in the early 1990s.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What company produced nylon and acrylic in the 1930s and 1940s?
Ah, so.. DuPont

Selfridges was established in 1909 by American-born Harry Gordon Selfridge on Oxford Street. The company's innovative marketing promoted the radical notion of shopping for pleasure rather than necessity and its techniques were adopted by modern department stores the world over. The store was extensively promoted through paid advertising. The shop floors were structured so that goods could be made more accessible to customers. There were elegant restaurants with modest prices, a library, reading and writing rooms, special reception rooms for French, German, American and "Colonial" customers, a First Aid Room, and a Silence Room, with soft lights, deep chairs, and double-glazing, all intended to keep customers in the store as long as possible. Staff members were taught to be on hand to assist customers, but not too aggressively, and to sell the merchandise. Selfridge attracted shoppers with educational and scientific exhibits; – in 1909, Louis Blériot's monoplane was exhibited at Selfridges (Blériot was the first to fly over the English Channel), and the first public demonstration of television by John Logie Baird took place in the department store in 1925.

Ah, so..
