question:
One poem by this author claims that "there's nothing sentimental about the technique of writing," which can be mastered by "any young man with a mind bursting to get out." This author argued that "The United States without self- seeking has given more of material help to Europe and to the world than have all other nations of the world put together in the entire history of mankind" in the chapter "Jacataqua," from a book which contains short biographies of people like Eric the Red, Walter Raleigh, and Daniel Boone. Another book by him begins with the section "The Delineaments of the Giants," which mentions "blank faces of the houses and cylindrical trees" to reinforce that there are "no ideas but in things," and describes a place that  "lies in the valley under the Passaic Falls, its spent waters forming the outline of his back." For 10 points, name this author of In the American Grain and an epic about his New Jersey hometown, Paterson.
answer:
Literature


question:
The earliest discovered writings on these were in the Hittite language and were authored by Kikkuli of Mitanni, while Gryson, an expert on these, helped Xenophon to write two treatises on the subject. Tupac Amaru II and Francois Ravaillac were both executed using four of these, and one of these named Incitatus was legendarily appointed as a Roman senator by Caligula. The Avars brought an invention that eased their use to Europe, and huge masses of these were instrumental in saving the French army at Eylau. Many cities were named after of these owned by Alexander the Great, Bucephalus. For 10 points, name these animals used to transport hussars and knights.
answer:
Literature


question:
Although not a primary alcohol, only one of these compounds with a methyl group undergoes the iodoform reaction. Their simplest example is mixed with sulfuric acid to form Marquis' reagent, which can be used to identify alkaloids. LDA usually cannot be used to deprotonate these compounds to form enolates because self-condensation is too fast. These compounds are transformed into an alkyne by the Corey-Fuchs reaction. When these compounds lack an alpha-hydrogen, they can undergo disproportionation to yield an alcohol and a salt of a carboxylic acid in the Cannizzaro reaction. Unlike a similar organic compound, they have reducing properties, which results in their oxidation in Tollens' reagent, creating a silver mirror. That mirror distinguishes them from ketones. For 10 points, identify these compounds that contain a formyl group and whose simplest example has chemical formula CH2O.
