Problem: Please answer a question about the following article about Tucson, Arizona:
At the end of the first decade of the 21st century, downtown Tucson underwent a revitalization effort by city planners and the business community. The primary project was Rio Nuevo, a large retail and community center that has been stalled in planning for more than ten years. Downtown is generally regarded as the area bordered by 17th Street to the south, I-10 to the west, and 6th Street to the north, and Toole Avenue and the Union Pacific (formerly Southern Pacific) railroad tracks, site of the historic train depot and "Locomotive #1673", built in 1900. Downtown is divided into the Presidio District, the Barrio Viejo, and the Congress Street Arts and Entertainment District. Some authorities include the 4th Avenue shopping district, which is set just northeast of the rest of downtown and connected by an underpass beneath the UPRR tracks.
What was the name of the retail and community center that took longer than a decade to build?
A: Rio Nuevo
Problem: Please answer a question about the following article about Seven Years%27 War:
Realizing that war was imminent, Prussia preemptively struck Saxony and quickly overran it. The result caused uproar across Europe. Because of Prussia's alliance with Britain, Austria formed an alliance with France, seeing an opportunity to recapture Silesia, which had been lost in a previous war. Reluctantly, by following the imperial diet, most of the states of the empire joined Austria's cause. The Anglo-Prussian alliance was joined by smaller German states (especially Hanover). Sweden, fearing Prussia's expansionist tendencies, went to war in 1757 to protect its Baltic dominions, seeing its chance when virtually all of Europe opposed Prussia. Spain, bound by the Pacte de Famille, intervened on behalf of France and together they launched an utterly unsuccessful invasion of Portugal in 1762. The Russian Empire was originally aligned with Austria, fearing Prussia's ambition on the Polish-Lithuanian Commonwealth, but switched sides upon the succession of Tsar Peter III in 1762.
What was the initial country to ally with France?
A: Austria formed an alliance with France
Problem: Please answer a question about the following article about Alps:
Jean-Jacques Rousseau was the first of many to present the Alps as a place of allure and beauty, banishing the prevalent conception of the mountains as a hellish wasteland inhabited by demons. Rousseau's conception of alpine purity was later emphasized with the publication of Albrecht von Haller's poem Die Alpen that described the mountains as an area of mythical purity. Late in the 18th century the first wave of Romantics such as Goethe and Turner came to admire the scenery; Wordsworth visited the area in 1790, writing of his experiences in The Prelude. Schiller later wrote the play William Tell romanticising Swiss independence. After the end of the Napoleonic Wars, the Alpine countries began to see an influx of poets, artists, and musicians, as visitors came to experience the sublime effects of monumental nature.
What did the visitors come to experience in the Alpine countries?
A: the sublime effects of monumental nature
Problem: Please answer a question about the following article about Geological history of Earth:
Earth was initially molten due to extreme volcanism and frequent collisions with other bodies. Eventually, the outer layer of the planet cooled to form a solid crust when water began accumulating in the atmosphere. The Moon formed soon afterwards, possibly as the result of a Mars-sized object with about 10% of the Earth's mass impacting the planet in a glancing blow. Some of this object's mass merged with the Earth, significantly altering its internal composition, and a portion was ejected into space. Some of the material survived to form an orbiting moon. Outgassing and volcanic activity produced the primordial atmosphere. Condensing water vapor, augmented by ice delivered from comets, produced the oceans.
What created a primordial atmosphere on earth?
A:
Outgassing and volcanic activity
