Problem: Please answer a question about the following article about Pharmaceutical industry:
The thalidomide tragedy resurrected Kefauver's bill to enhance drug regulation that had stalled in Congress, and the Kefauver-Harris Amendment became law on 10 October 1962. Manufacturers henceforth had to prove to FDA that their drugs were effective as well as safe before they could go on the US market. The FDA received authority to regulate advertising of prescription drugs and to establish good manufacturing practices. The law required that all drugs introduced between 1938 and 1962 had to be effective. An FDA - National Academy of Sciences collaborative study showed that nearly 40 percent of these products were not effective. A similarly comprehensive study of over-the-counter products began ten years later.
What did this new law require?
A: all drugs introduced between 1938 and 1962 had to be effective
Problem: Please answer a question about the following article about Culture:
Cultural sociology first emerged in Weimar Germany (1918–1933), where sociologists such as Alfred Weber used the term Kultursoziologie (cultural sociology). Cultural sociology was then "reinvented" in the English-speaking world as a product of the "cultural turn" of the 1960s, which ushered in structuralist and postmodern approaches to social science. This type of cultural sociology may loosely be regarded as an approach incorporating cultural analysis and critical theory. Cultural sociologists tend to reject scientific methods,[citation needed] instead hermeneutically focusing on words, artifacts and symbols. "Culture" has since become an important concept across many branches of sociology, including resolutely scientific fields like social stratification and social network analysis. As a result, there has been a recent influx of quantitative sociologists to the field. Thus there is now a growing group of sociologists of culture who are, confusingly, not cultural sociologists. These scholars reject the abstracted postmodern aspects of cultural sociology, and instead look for a theoretical backing in the more scientific vein of social psychology and cognitive science. "Cultural sociology" is one of the largest sections of the American Sociological Association. The British establishment of cultural studies means the latter is often taught as a loosely distinct discipline in the UK.
Who was the first to refer to culture as sociology?
A: Alfred Weber
Problem: Please answer a question about the following article about Alloy:
When the alloy cools and solidifies (crystallizes), its mechanical properties will often be quite different from those of its individual constituents. A metal that is normally very soft and malleable, such as aluminium, can be altered by alloying it with another soft metal, like copper. Although both metals are very soft and ductile, the resulting aluminium alloy will be much harder and stronger. Adding a small amount of non-metallic carbon to iron produces an alloy called steel. Due to its very-high strength and toughness (which is much higher than pure iron), and its ability to be greatly altered by heat treatment, steel is one of the most common alloys in modern use. By adding chromium to steel, its resistance to corrosion can be enhanced, creating stainless steel, while adding silicon will alter its electrical characteristics, producing silicon steel.
What is superior to pure iron?
A: steel
Problem: Please answer a question about the following article about Botany:
Phytochemistry is a branch of plant biochemistry primarily concerned with the chemical substances produced by plants during secondary metabolism. Some of these compounds are toxins such as the alkaloid coniine from hemlock. Others, such as the essential oils peppermint oil and lemon oil are useful for their aroma, as flavourings and spices (e.g., capsaicin), and in medicine as pharmaceuticals as in opium from opium poppies. Many medicinal and recreational drugs, such as tetrahydrocannabinol (active ingredient in cannabis), caffeine, morphine and nicotine come directly from plants. Others are simple derivatives of botanical natural products. For example, the pain killer aspirin is the acetyl ester of salicylic acid, originally isolated from the bark of willow trees, and a wide range of opiate painkillers like heroin are obtained by chemical modification of morphine obtained from the opium poppy. Popular stimulants come from plants, such as caffeine from coffee, tea and chocolate, and nicotine from tobacco. Most alcoholic beverages come from fermentation of carbohydrate-rich plant products such as barley (beer), rice (sake) and grapes (wine).
Hemlock is what kind of chemical produced from a plant?
A:
toxins
