Student A:The three major constituents of air, and therefore of Earth's atmosphere, are nitrogen, oxygen, and argon. Water vapor accounts for roughly 0.25 % of the atmosphere by mass. The concentration of water vapor (a greenhouse gas) varies significantly from around 10 ppm by volume in the coldest portions of the atmosphere to as much as 5 % by volume in hot, humid air masses, and concentrations of other atmospheric gases are typically quoted in terms of dry air (without water vapor). The remaining gases are often referred to as trace gases, among which are the greenhouse gases, principally carbon dioxide, methane, nitrous oxide, and ozone. Filtered air includes trace amounts of many other chemical compounds. Many substances of natural origin may be present in locally and seasonally variable small amounts as aerosols in an unfiltered air sample, including dust of mineral and organic composition, pollen and spores, sea spray, and volcanic ash. Various industrial pollutants also may be present as gases or aerosols, such as chlorine (elemental or in compounds), fluorine compounds and elemental mercury vapor. Sulfur compounds such as hydrogen sulfide and sulfur dioxide (SO) may be derived from natural sources or from industrial air pollution.

Answer this question based on the passage: what are the main components of earth's atmosphere?
Student B:OK... This is the relevant information: The three major constituents of air, and therefore of Earth's atmosphere, are nitrogen, oxygen, and argon.

Problem:The just-world hypothesis or just-world fallacy is the cognitive bias (or assumption) that a person's actions are inherently inclined to bring morally fair and fitting consequences to that person, to the end of all noble actions being eventually rewarded and all evil actions eventually punished. In other words, the just-world hypothesis is the tendency to attribute consequences to -- or expect consequences as the result of -- a universal force that restores moral balance. This belief generally implies the existence of cosmic justice, destiny, divine providence, desert, stability, or order, and has high potential to result in fallacy, especially when used to rationalize people's misfortune on the grounds that they "deserve" it.

Problem:Passage: The first use of X-rays under clinical conditions was by John Hall-Edwards in Birmingham, England on 11 January 1896, when he radiographed a needle stuck in the hand of an associate. On February 14, 1896 Hall-Edwards was also the first to use X-rays in a surgical operation. In early 1896, several weeks after Röntgen's discovery, Ivan Romanovich Tarkhanov irradiated frogs and insects with X-rays, concluding that the rays "not only photograph, but also affect the living function".

Question: Based on this passage, when were x rays first used in medicine?
Solution:OK... The relevant information is: The first use of X-rays under clinical conditions was by John Hall-Edwards in Birmingham, England on 11 January 1896, when he radiographed a needle stuck in the hand of an associate.
11 January 1896.

Student A:Passage: Ancient Greece was a civilization belonging to a period of Greek history from the Greek Dark Ages of the 13th -- 9th centuries BC to the end of antiquity (c. 600 AD). Immediately following this period was the beginning of the Early Middle Ages and the Byzantine era. Roughly three centuries after the Late Bronze Age collapse of Mycenaean Greece, Greek urban poleis began to form in the 8th century BC, ushering in the period of Archaic Greece and colonization of the Mediterranean Basin. This was followed by the period of Classical Greece, an era that began with the Greco-Persian Wars, lasting from the 5th to 4th centuries BC. Due to the conquests by Alexander the Great of Macedonia, Hellenistic civilization flourished from Central Asia to the western end of the Mediterranean Sea. The Hellenistic period came to an end with the conquests and annexations of the eastern Mediterranean world by the Roman Republic, which established the Roman province of Macedonia in Roman Greece, and later the province of Achaea during the Roman Empire.
