The immediate cause of the war resided in the candidacy of a Leopold of Hohenzollern-Sigmaringen, a Prussian prince, to the throne of Spain. France feared encirclement by an alliance between Prussia and Spain. The Hohenzollern prince's candidacy was withdrawn under French diplomatic pressure, but Otto von Bismarck goaded the French into declaring war by altering a telegram sent by William I. Releasing the Ems Dispatch to the public, Bismarck made it sound as if the king had treated the French envoy in a demeaning fashion, which inflamed public opinion in France.
What did France fear by an alliance between Prussia and Spain?

Input: Alexander Graham Bell
In 1865, when the Bell family moved to London, Bell returned to Weston House as an assistant master and, in his spare hours, continued experiments on sound using a minimum of laboratory equipment. Bell concentrated on experimenting with electricity to convey sound and later installed a telegraph wire from his room in Somerset College to that of a friend. Throughout late 1867, his health faltered mainly through exhaustion. His younger brother, Edward "Ted," was similarly bed-ridden, suffering from tuberculosis. While Bell recovered (by then referring to himself in correspondence as "A.G. Bell") and served the next year as an instructor at Somerset College, Bath, England, his brother's condition deteriorated. Edward would never recover. Upon his brother's death, Bell returned home in 1867. His older brother Melville had married and moved out. With aspirations to obtain a degree at University College London, Bell considered his next years as preparation for the degree examinations, devoting his spare time at his family's residence to studying.

Where did Bell go in work in 1865?

Input: Article: The island of Guam is 30 miles (50 km) long and 4 to 12 miles (6 to 19 km) wide, 3⁄4 the size of Singapore. The island experiences occasional earthquakes due to its location on the western edge of the Pacific Plate and near the Philippine Sea Plate. In recent years, earthquakes with epicenters near Guam have had magnitudes ranging from 5.0 to 8.7. Unlike the Anatahan volcano in the Northern Mariana Islands, Guam is not volcanically active. However, due to its proximity to Anatahan, vog (i.e. volcanic smog) does occasionally affect Guam.

Now answer this question: Due to Guam being so close to Anatahan, what dod they have to worry about?

Output: volcanic smog


Article: AOC Bomber Command Arthur Harris did see German morale as a major objective. However, he did not believe that the morale-collapse could occur without the destruction of the German economy. The primary goal of Bomber Command's offensives was to destroy the German industrial base (economic warfare), and in doing so reduce morale. In late 1943, just before the Battle of Berlin, he declared the power of Bomber Command would enable it to achieve "a state of devastation in which surrender is inevitable." A summary of Harris' strategic intentions was clear:

Question: Without what could morale collapse occur according to Arthur Harris?
Ans: without the destruction of the German economy.


Here is a question about this article: The Richmond area also has two railroad stations served by Amtrak. Each station receives regular service from north of Richmond including Washington, D.C., Philadelphia, and New York. The suburban Staples Mill Road Station is located on a major north-south freight line and receives all service to and from all points south including, Raleigh, Durham, Savannah, Newport News, Williamsburg and Florida. Richmond's only railway station located within the city limits, the historic Main Street Station, was renovated in 2004. As of 2010, the station only receives trains headed to and from Newport News and Williamsburg due to track layout. As a result, the Staples Mill Road station receives more trains and serves more passengers overall.
What is the answer to this question: What station services all southern rail traffic passing through Richmond?
****
So... Staples Mill Road Station


Article: The inventor Nicéphore Niépce produced the first permanent photograph on a polished pewter plate in Paris in 1825, and then developed the process with Louis Daguerre. The work of Étienne-Jules Marey in the 1880s contributed considerably to the development of modern photography. Photography came to occupy a central role in Parisian Surrealist activity, in the works of Man Ray and Maurice Tabard. Numerous photographers achieved renown for their photography of Paris, including Eugène Atget, noted for his depictions of street scenes, Robert Doisneau, noted for his playful pictures of people and market scenes (among which Le baiser de l'hôtel de ville has became iconic of the romantic vision of Paris), Marcel Bovis, noted for his night scenes, and others such as Jacques-Henri Lartigue and Cartier-Bresson. Poster art also became an important art form in Paris in the late nineteenth century, through the work of Henri de Toulouse-Lautrec, Jules Chéret, Eugène Grasset, Adolphe Willette, Pierre Bonnard, Georges de Feure, Henri-Gabriel Ibels, Gavarni, and Alphonse Mucha.

Question: When did poster art become an important art form?
Ans:
late nineteenth century
