QUES: In his native Poland, in France, where he composed most of his works, and beyond, Chopin's music, his status as one of music's earliest superstars, his association (if only indirect) with political insurrection, his love life and his early death have made him, in the public consciousness, a leading symbol of the Romantic era. His works remain popular, and he has been the subject of numerous films and biographies of varying degrees of historical accuracy.

Chopin is considered a prominent symbol of what?
What is the answer?

QUES: Chopin seldom performed publicly in Paris. In later years he generally gave a single annual concert at the Salle Pleyel, a venue that seated three hundred. He played more frequently at salons, but preferred playing at his own Paris apartment for small groups of friends. The musicologist Arthur Hedley has observed that "As a pianist Chopin was unique in acquiring a reputation of the highest order on the basis of a minimum of public appearances—few more than thirty in the course of his lifetime." The list of musicians who took part in some of his concerts provides an indication of the richness of Parisian artistic life during this period. Examples include a concert on 23 March 1833, in which Chopin, Liszt and Hiller performed (on pianos) a concerto by J.S. Bach for three keyboards; and, on 3 March 1838, a concert in which Chopin, his pupil Adolphe Gutmann, Charles-Valentin Alkan, and Alkan's teacher Joseph Zimmermann performed Alkan's arrangement, for eight hands, of two movements from Beethoven's 7th symphony. Chopin was also involved in the composition of Liszt's Hexameron; he wrote the sixth (and final) variation on Bellini's theme. Chopin's music soon found success with publishers, and in 1833 he contracted with Maurice Schlesinger, who arranged for it to be published not only in France but, through his family connections, also in Germany and England.
Who did Chopin contract with for publishing his music?

ANS: Maurice Schlesinger

Question: In June 2006, Steven Spielberg announced he would direct a scientifically accurate film about "a group of explorers who travel through a worm hole and into another dimension", from a treatment by Kip Thorne and producer Lynda Obst. In January 2007, screenwriter Jonathan Nolan met with them to discuss adapting Obst and Thorne's treatment into a narrative screenplay. The screenwriter suggested the addition of a "time element" to the treatment's basic idea, which was welcomed by Obst and Thorne. In March of that year, Paramount hired Nolan, as well as scientists from Caltech, forming a workshop to adapt the treatment under the title Interstellar. The following July, Kip Thorne said there was a push by people for him to portray himself in the film. Spielberg later abandoned Interstellar, which was eventually directed by Christopher Nolan.
Try to answer this question if possible: In what year did Christopher Nolan become a director?
Answer: unanswerable


QUES: The Paris department store had its roots in the magasin de nouveautés, or novelty store; the first, the Tapis Rouge, was created in 1784. They flourished in the early 19th century, with La Belle Jardiniere (1824), Aux Trois Quartiers (1829), and Le Petit Saint Thomas (1830). Balzac described their functioning in his novel César Birotteau. In the 1840s, with the arrival of the railroads in Paris and the increased number of shoppers they brought, they grew in size, and began to have large plate glass display windows, fixed prices and price tags, and advertising in newspapers.
What factors influenced the increase of department stores in Paris?
