Article: In non-relativistic classical mechanics, Newton's concept of "relative, apparent, and common time" can be used in the formulation of a prescription for the synchronization of clocks. Events seen by two different observers in motion relative to each other produce a mathematical concept of time that works sufficiently well for describing the everyday phenomena of most people's experience. In the late nineteenth century, physicists encountered problems with the classical understanding of time, in connection with the behavior of electricity and magnetism. Einstein resolved these problems by invoking a method of synchronizing clocks using the constant, finite speed of light as the maximum signal velocity. This led directly to the result that observers in motion relative to one another measure different elapsed times for the same event.

Question: The behavior of which two phenomena caused physicists to encounter problems with their understanding of time in the late 19th century?
Ans: the behavior of electricity and magnetism

Article: Modern standard Italian itself is heavily based on the Latin-derived Florentine Tuscan language. The Tuscan-based language that would eventually become modern standard Italian had been used in poetry and literature since at least the 12th century, and it first became widely known in Italy through the works of authors such as Dante Alighieri, Giovanni Boccaccio, Niccolo Machiavelli, and Petrarch. Dante's Florentine-Tuscan literary Italian thus became the language of the literate and upper class in Italy, and it spread throughout the peninsula as the lingua franca among the Italian educated class as well as Italian traveling merchants. The economic prowess and cultural and artistic importance of Tuscany in the Late Middle Ages and the Renaissance further encouraged the diffusion of the Florentine-Tuscan Italian throughout Italy and among the educated and powerful, though local and regional languages remained the main languages of the common people.

Question: What language is Florentine Tuscan based on?
Ans: Latin

Article: The community was established by several shiploads of settlers from Bermuda (which lies due east of South Carolina, although at 1,030 km or 640 mi, it is closest to Cape Hatteras, North Carolina), under the leadership of governor William Sayle, on the west bank of the Ashley River, a few miles northwest of the present-day city center. It was soon predicted by the Earl of Shaftesbury, one of the Lords Proprietors, to become a "great port towne", a destiny the city quickly fulfilled. In 1680, the settlement was moved east of the Ashley River to the peninsula between the Ashley and Cooper Rivers. Not only was this location more defensible, but it also offered access to a fine natural harbor.

Question: The settlement was relocated east to what river?
Ans: Ashley River

Article: United States President Barack Obama and key advisers introduced a series of regulatory proposals in June 2009. The proposals address consumer protection, executive pay, bank financial cushions or capital requirements, expanded regulation of the shadow banking system and derivatives, and enhanced authority for the Federal Reserve to safely wind-down systemically important institutions, among others. In January 2010, Obama proposed additional regulations limiting the ability of banks to engage in proprietary trading. The proposals were dubbed "The Volcker Rule", in recognition of Paul Volcker, who has publicly argued for the proposed changes.

Question: What was introduced by President Barack Obama in June 2009?
Ans:
a series of regulatory proposals
