Problem: Anti-aircraft warfare:

AAA battalions were also used to help suppress ground targets. Their larger 90 mm M3 gun would prove, as did the eighty-eight, to make an excellent anti-tank gun as well, and was widely used late in the war in this role. Also available to the Americans at the start of the war was the 120 mm M1 gun stratosphere gun, which was the most powerful AA gun with an impressive 60,000 ft (18 km) altitude capability. No 120 M1 was ever fired at an enemy aircraft. The 90 mm and 120 mm guns would continue to be used into the 1950s.

What did the Americans use at the beginning of the war?

A: 120 mm M1 gun stratosphere gun


Problem: The biographical tradition asserts that Virgil began the hexameter Eclogues (or Bucolics) in 42 BC and it is thought that the collection was published around 39–38 BC, although this is controversial. The Eclogues (from the Greek for "selections") are a group of ten poems roughly modeled on the bucolic hexameter poetry ("pastoral poetry") of the Hellenistic poet Theocritus. After his victory in the Battle of Philippi in 42 BC, fought against the army led by the assassins of Julius Caesar, Octavian tried to pay off his veterans with land expropriated from towns in northern Italy, supposedly including, according to the tradition, an estate near Mantua belonging to Virgil. The loss of his family farm and the attempt through poetic petitions to regain his property have traditionally been seen as Virgil's motives in the composition of the Eclogues. This is now thought to be an unsupported inference from interpretations of the Eclogues. In Eclogues 1 and 9, Virgil indeed dramatizes the contrasting feelings caused by the brutality of the land expropriations through pastoral idiom, but offers no indisputable evidence of the supposed biographic incident. While some readers have identified the poet himself with various characters and their vicissitudes, whether gratitude by an old rustic to a new god (Ecl. 1), frustrated love by a rustic singer for a distant boy (his master's pet, Ecl. 2), or a master singer's claim to have composed several eclogues (Ecl. 5), modern scholars largely reject such efforts to garner biographical details from works of fiction, preferring to interpret an author's characters and themes as illustrations of contemporary life and thought. The ten Eclogues present traditional pastoral themes with a fresh perspective. Eclogues 1 and 9 address the land confiscations and their effects on the Italian countryside. 2 and 3 are pastoral and erotic, discussing both homosexual love (Ecl. 2) and attraction toward people of any gender (Ecl. 3). Eclogue 4, addressed to Asinius Pollio, the so-called "Messianic Eclogue" uses the imagery of the golden age in connection with the birth of a child (who the child was meant to be has been subject to debate). 5 and 8 describe the myth of Daphnis in a song contest, 6, the cosmic and mythological song of Silenus; 7, a heated poetic contest, and 10 the sufferings of the contemporary elegiac poet Cornelius Gallus. Virgil is credited[by whom?] in the Eclogues with establishing Arcadia as a poetic ideal that still resonates in Western literature and visual arts and setting the stage for the development of Latin pastoral by Calpurnius Siculus, Nemesianus, and later writers.

Other historians find incongruity in the proposition that the very place where the vast number of the scholars that influenced the scientific revolution received their education should also be the place that inhibits their research and the advancement of science. In fact, more than 80% of the European scientists between 1450–1650 included in the Dictionary of Scientific Biography were university trained, of which approximately 45% held university posts. It was the case that the academic foundations remaining from the Middle Ages were stable, and they did provide for an environment that fostered considerable growth and development. There was considerable reluctance on the part of universities to relinquish the symmetry and comprehensiveness provided by the Aristotelian system, which was effective as a coherent system for understanding and interpreting the world. However, university professors still utilized some autonomy, at least in the sciences, to choose epistemological foundations and methods. For instance, Melanchthon and his disciples at University of Wittenberg were instrumental for integrating Copernican mathematical constructs into astronomical debate and instruction. Another example was the short-lived but fairly rapid adoption of Cartesian epistemology and methodology in European universities, and the debates surrounding that adoption, which led to more mechanistic approaches to scientific problems as well as demonstrated an openness to change. There are many examples which belie the commonly perceived intransigence of universities. Although universities may have been slow to accept new sciences and methodologies as they emerged, when they did accept new ideas it helped to convey legitimacy and respectability, and supported the scientific changes through providing a stable environment for instruction and material resources.
What type of epistemology was adopted for a short period of time in European universities?
A: Cartesian


Context and question: On 27 June, Rhee evacuated from Seoul with some of the government. On 28 June, at 2 am, the South Korean Army blew up the highway bridge across the Han River in an attempt to stop the North Korean army. The bridge was detonated while 4,000 refugees were crossing the bridge, and hundreds were killed. Destroying the bridge also trapped many South Korean military units north of the Han River. In spite of such desperate measures, Seoul fell that same day. A number of South Korean National Assemblymen remained in Seoul when it fell, and forty-eight subsequently pledged allegiance to the North.
What bridge were refugees attempting to cross when it was blown up by the South Korean Army?
Answer: Han River


Question: Corruption is often most evident in countries with the smallest per capita incomes, relying on foreign aid for health services. Local political interception of donated money from overseas is especially prevalent in Sub-Saharan African nations, where it was reported in the 2006 World Bank Report that about half of the funds that were donated for health usages were never invested into the health sectors or given to those needing medical attention.
Is there an answer to this question: How many funds did not reach their intended recipients who needed medical attention?

Answer: about half

Microbiological culture is a principal tool used to diagnose infectious disease. In a microbial culture, a growth medium is provided for a specific agent. A sample taken from potentially diseased tissue or fluid is then tested for the presence of an infectious agent able to grow within that medium. Most pathogenic bacteria are easily grown on nutrient agar, a form of solid medium that supplies carbohydrates and proteins necessary for growth of a bacterium, along with copious amounts of water. A single bacterium will grow into a visible mound on the surface of the plate called a colony, which may be separated from other colonies or melded together into a "lawn". The size, color, shape and form of a colony is characteristic of the bacterial species, its specific genetic makeup (its strain), and the environment that supports its growth. Other ingredients are often added to the plate to aid in identification. Plates may contain substances that permit the growth of some bacteria and not others, or that change color in response to certain bacteria and not others. Bacteriological plates such as these are commonly used in the clinical identification of infectious bacterium. Microbial culture may also be used in the identification of viruses: the medium in this case being cells grown in culture that the virus can infect, and then alter or kill. In the case of viral identification, a region of dead cells results from viral growth, and is called a "plaque". Eukaryotic parasites may also be grown in culture as a means of identifying a particular agent.
What is a planet of dead cells resulting from viral growth called?
A:
