Passage: The U.S. Army currently consists of 10 active divisions as well as several independent units. The force is in the process of contracting after several years of growth. In June 2013, the Army announced plans to downsize to 32 active combat brigade teams by 2015 to match a reduction in active duty strength to 490,000 soldiers. Army Chief of Staff Raymond Odierno has projected that by 2018 the Army will eventually shrink to "450,000 in the active component, 335,000 in the National Guard and 195,000 in U.S. Army Reserve."
How many divisions are there in the U.S. Navy?

Passage: 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.
When did the FDA Amendment become a law?

Passage: The sociology of culture concerns culture—usually understood as the ensemble of symbolic codes used by a society—as manifested in society. For Georg Simmel (1858–1918), culture referred to "the cultivation of individuals through the agency of external forms which have been objectified in the course of history". Culture in the sociological field can be defined as the ways of thinking, the ways of acting, and the material objects that together shape a people's way of life. Culture can be any of two types, non-material culture or material culture. Non-material culture refers to the non physical ideas that individuals have about their culture, including values, belief system, rules, norms, morals, language, organizations, and institutions. While Material culture is the physical evidence of a culture in the objects and architecture they make, or have made. The term tends to be relevant only in archeological and anthropological studies, but it specifically means all material evidence which can be attributed to culture past or present.

Who referred to culture as a cultivation of groups?
