The almost constant wars among the Sumerian city-states for 2000 years helped to develop the military technology and techniques of Sumer to a high level. The first war recorded in any detail was between Lagash and Umma in c. 2525 BC on a stele called the Stele of the Vultures. It shows the king of Lagash leading a Sumerian army consisting mostly of infantry. The infantrymen carried spears, wore copper helmets, and carried rectangular shields. The spearmen are shown arranged in what resembles the phalanx formation, which requires training and discipline; this implies that the Sumerians may have made use of professional soldiers.
What shape were the shields of the infantry of Lagash?
****
The answer: rectangular

Like other American research universities, Northwestern was transformed by World War II. Franklyn B. Snyder led the university from 1939 to 1949, when nearly 50,000 military officers and personnel were trained on the Evanston and Chicago campuses. After the war, surging enrollments under the G.I. Bill drove drastic expansion of both campuses. In 1948 prominent anthropologist Melville J. Herskovits founded the Program of African Studies at Northwestern, the first center of its kind at an American academic institution. J. Roscoe Miller's tenure as president from 1949 to 1970 was responsible for the expansion of the Evanston campus, with the construction of the lakefill on Lake Michigan, growth of the faculty and new academic programs, as well as polarizing Vietnam-era student protests. In 1978, the first and second Unabomber attacks occurred at Northwestern University. Relations between Evanston and Northwestern were strained throughout much of the post-war era because of episodes of disruptive student activism, disputes over municipal zoning, building codes, and law enforcement, as well as restrictions on the sale of alcohol near campus until 1972. Northwestern's exemption from state and municipal property tax obligations under its original charter has historically been a source of town and gown tension.
What center was founded by Melville J. Herskovits in 1948?
****
The answer: Program of African Studies at Northwestern

Tito's greatest strength, in the eyes of the western communists, had been in suppressing nationalist insurrections and maintaining unity throughout the country. It was Tito's call for unity, and related methods, that held together the people of Yugoslavia. This ability was put to a test several times during his reign, notably during the Croatian Spring (also referred as the Masovni pokret, maspok, meaning "Mass Movement") when the government suppressed both public demonstrations and dissenting opinions within the Communist Party. Despite this suppression, much of maspok's demands were later realized with the new constitution, heavily backed by Tito himself against opposition from the Serbian branch of the party.[citation needed] On 16 May 1974, the new Constitution was passed, and the aging Tito was named president for life, a status which he would enjoy for five years.
What was referred to as the "Mass Movement"?
****
The answer:
the Croatian Spring
