In the early 20th century came another turn toward nationalist politics with Solidaridad Gallega (1907–1912) modeled on Solidaritat Catalana in Catalonia. Solidaridad Gallega failed, but in 1916 Irmandades da Fala (Brotherhood of the Language) developed first as a cultural association but soon as a full-blown nationalist movement. Vicente Risco and Ramón Otero Pedrayo were outstanding cultural figures of this movement, and the magazine Nós ('Us'), founded 1920, its most notable cultural institution, Lois Peña Novo the outstanding political figure.
Which magazine advocated for Galician nationalism?
****
The answer: Nós


Problem: Please answer a question about the following article about Middle Ages:
By the end of the 5th century the western section of the empire was divided into smaller political units, ruled by the tribes that had invaded in the early part of the century. The deposition of the last emperor of the west, Romulus Augustus, in 476 has traditionally marked the end of the Western Roman Empire.[E] The Eastern Roman Empire, often referred to as the Byzantine Empire after the fall of its western counterpart, had little ability to assert control over the lost western territories. The Byzantine emperors maintained a claim over the territory, but none of the new kings in the west dared to elevate himself to the position of emperor of the west, Byzantine control of most of the Western Empire could not be sustained; the reconquest of the Italian peninsula and Mediterranean periphery by Justinian (r. 527–565) was the sole, and temporary, exception.
What Eastern Roman Emperor reconquered Italy?
A: Justinian


Question: Read this and answer the question

Capacitors may catastrophically fail when subjected to voltages or currents beyond their rating, or as they reach their normal end of life. Dielectric or metal interconnection failures may create arcing that vaporizes the dielectric fluid, resulting in case bulging, rupture, or even an explosion. Capacitors used in RF or sustained high-current applications can overheat, especially in the center of the capacitor rolls. Capacitors used within high-energy capacitor banks can violently explode when a short in one capacitor causes sudden dumping of energy stored in the rest of the bank into the failing unit. High voltage vacuum capacitors can generate soft X-rays even during normal operation. Proper containment, fusing, and preventive maintenance can help to minimize these hazards.

What type of capacitors can generate soft x-rays?
Answer: High voltage vacuum capacitors


Problem: Darwin had initially decided to call his book An abstract of an Essay on the Origin of Species and Varieties Through natural selection, but with Murray's persuasion it was eventually changed to the snappier title: On the Origin of Species, with the title page adding by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life. Here the term "races" is used as an alternative for "varieties" and does not carry the modern connotation of human races—the first use in the book refers to "the several races, for instance, of the cabbage" and proceeds to a discussion of "the hereditary varieties or races of our domestic animals and plants".
Who convinced Darwin that his book needed a shorter, more compelling title?
The answer is the following: Murray

Here is a question about this article: The scientific revolution is a convenient boundary between ancient thought and classical physics. Nicolaus Copernicus revived the heliocentric model of the solar system described by Aristarchus of Samos. This was followed by the first known model of planetary motion given by Johannes Kepler in the early 17th century, which proposed that the planets follow elliptical orbits, with the Sun at one focus of the ellipse. Galileo ("Father of Modern Physics") also made use of experiments to validate physical theories, a key element of the scientific method.
What is the answer to this question: Johannes Kepler created a model of what?
****
So...
planetary motion
