Evidence suggests that blast furnaces, that convert raw iron ore into pig iron, which can be remelted in a cupola furnace to produce cast iron by means of a cold blast and hot blast, were operational in China by the late Spring and Autumn period (722481 BC). The bloomery was nonexistent in ancient China; however, the Han-era Chinese produced wrought iron by injecting excess oxygen into a furnace and causing decarburization. Cast iron and pig iron could be converted into wrought iron and steel using a fining process.
What type of iron could pig iron be converted into?
A: wrought

The poets generally associated with Cubism are Guillaume Apollinaire, Blaise Cendrars, Jean Cocteau, Max Jacob, Andre Salmon and Pierre Reverdy. As American poet Kenneth Rexroth explains, Cubism in poetry "is the conscious, deliberate dissociation and recombination of elements into a new artistic entity made self-sufficient by its rigorous architecture. This is quite different from the free association of the Surrealists and the combination of unconscious utterance and political nihilism of Dada." Nonetheless, the Cubist poets' influence on both Cubism and the later movements of Dada and Surrealism was profound; Louis Aragon, founding member of Surrealism, said that for Breton, Soupault, Eluard and himself, Reverdy was "our immediate elder, the exemplary poet." Though not as well remembered as the Cubist painters, these poets continue to influence and inspire; American poets John Ashbery and Ron Padgett have recently produced new translations of Reverdy's work. Wallace Stevens' "Thirteen Ways of Looking at a Blackbird" is also said to demonstrate how cubism's multiple perspectives can be translated into poetry.
Which three American poets have recently created new traslations of Reverdy's work?
A: unanswerable

On Sentinel Peak (also known as "'A' Mountain"), just west of downtown, there is a giant "A" in honor of the University of Arizona. Starting in about 1916, a yearly tradition developed for freshmen to whitewash the "A", which was visible for miles. However, at the beginning of the Iraq War, anti-war activists painted it black. This was followed by a paint scuffle where the "A" was painted various colors until the city council intervened. It is now red, white and blue except when it is white or another color decided by a biennial election. Because of the three-color paint scheme often used, the shape of the A can be vague and indistinguishable from the rest of the peak. The top of Sentinel Peak, which is accessible by road, offers an outstanding scenic view of the city looking eastward. A parking lot located near the summit of Sentinel Peak was formerly a popular place to watch sunsets or view the city lights at night.
What color did college freshmen paint the A?
A: white

Kievan Rus' also played an important genealogical role in European politics. Yaroslav the Wise, whose stepmother belonged to the Macedonian dynasty, the greatest one to rule Byzantium, married the only legitimate daughter of the king who Christianized Sweden. His daughters became queens of Hungary, France and Norway, his sons married the daughters of a Polish king and a Byzantine emperor (not to mention a niece of the Pope), while his granddaughters were a German Empress and (according to one theory) the queen of Scotland. A grandson married the only daughter of the last Anglo-Saxon king of England. Thus the Rurikids were a well-connected royal family of the time.
What did not play an important role in European politics?
A:
unanswerable
