Problem: Botany:

Physician Valerius Cordus (15151544) authored a botanically and pharmacologically important herbal Historia Plantarum in 1544 and a pharmacopoeia of lasting importance, the Dispensatorium in 1546. Naturalist Conrad von Gesner (15161565) and herbalist John Gerard (1545c. 1611) published herbals covering the medicinal uses of plants. Naturalist Ulisse Aldrovandi (15221605) was considered the father of natural history, which included the study of plants. In 1665, using an early microscope, Polymath Robert Hooke discovered cells, a term he coined, in cork, and a short time later in living plant tissue.

Who is considered the father of natural history?

Problem: In the 1950s after PRC was established by CPC, the government invested heavily in the city to build a series of state-owned heavy industries, as part of the national plan of rapid industrialization, converting it into a heavy industry production centre of East China. Overenthusiastic in building a "world-class" industrial city, the government also made many disastrous mistakes during development, such as spending hundreds of millions of yuan to mine for non-existent coal, resulting in negative economic growth in the late 1960s. From 1960s to 1980s there were Five Pillar Industries, namely, electronics, cars, petrochemical, iron and steel, and power, each with big state-owned firms. After the Reform and Opening recovering market economy, the state-owned enterprises found themselves incapable of competing with efficient multinational firms and local private firms, hence were either mired in heavy debt or forced into bankruptcy or privatization and this resulted in large numbers of layoff workers who were technically not unemployed but effectively jobless.
What did the government build in Nanjing during the 1950's?

Although most of the simplified Chinese characters in use today are the result of the works moderated by the government of the People's Republic of China in the 1950s and 60s, character simplification predates the republic's formation in 1949. One of the earliest proponents of character simplification was Lufei Kui, who proposed in 1909 that simplified characters should be used in education. In the years following the May Fourth Movement in 1919, many anti-imperialist Chinese intellectuals sought ways to modernise China. In the 1930s and 1940s, discussions on character simplification took place within the Kuomintang government, and many Chinese intellectuals and writers have long maintained that character simplification would help boost literacy in China. In many world languages, literacy has been promoted as a justification for spelling reforms. The People's Republic of China issued its first round of official character simplifications in two documents, the first in 1956 and the second in 1964. In the 1950s and 1960s, while confusion about simplified characters was still rampant, transitional characters that mixed simplified parts with yet-to-be simplified parts of characters together appeared briefly, then disappeared.
Character simplification predated the republic's formation in what year?
A: 1949

Context and question: The influence of cubism extended to other artistic fields, outside painting and sculpture. In literature, the written works of Gertrude Stein employ repetition and repetitive phrases as building blocks in both passages and whole chapters. Most of Stein's important works utilize this technique, including the novel The Making of Americans (190608). Not only were they the first important patrons of Cubism, Gertrude Stein and her brother Leo were also important influences on Cubism as well. Picasso in turn was an important influence on Stein's writing.
Did cubism influence other fields outside of painting and scuplture?
Answer: The influence of cubism extended to other artistic fields,

Guinea fowl originated in southern Africa, and the species most often kept as poultry is the helmeted guineafowl (Numida meleagris). It is a medium-sized grey or speckled bird with a small naked head with colourful wattles and a knob on top, and was domesticated by the time of the ancient Greeks and Romans. Guinea fowl are hardy, sociable birds that subsist mainly on insects, but also consume grasses and seeds. They will keep a vegetable garden clear of pests and will eat the ticks that carry Lyme disease. They happily roost in trees and give a loud vocal warning of the approach of predators. Their flesh and eggs can be eaten in the same way as chickens, young birds being ready for the table at the age of about four months.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Aside from consumption how are Guinea fowl useful to humans.
Ah, so..
They will keep a vegetable garden clear of pests and will eat the ticks that carry Lyme disease.
