Input: Read this: By 17 May, the main Austrian army under Charles had arrived on the Marchfeld. Charles kept the bulk of his troops several miles away from the river bank in hopes of concentrating them at the point where Napoleon decided to cross. On 21 May, the French made their first major effort to cross the Danube, precipitating the Battle of Aspern-Essling. The Austrians enjoyed a comfortable numerical superiority over the French throughout the battle; on the first day, Charles disposed of 110,000 soldiers against only 31,000 commanded by Napoleon. By the second day, reinforcements had boosted French numbers up to 70,000. The battle was characterized by a vicious back-and-forth struggle for the two villages of Aspern and Essling, the focal points of the French bridgehead. By the end of the fighting, the French had lost Aspern but still controlled Essling. A sustained Austrian artillery bombardment eventually convinced Napoleon to withdraw his forces back onto Lobau Island. Both sides inflicted about 23,000 casualties on each other. It was the first defeat Napoleon suffered in a major set-piece battle, and it caused excitement throughout many parts of Europe because it proved that he could be beaten on the battlefield.
Question: On what date did French forces make their first significant attempt to cross the Danube?

Output: 21 May

QUES: The per capita income of the Republic is often listed as being approximately $400 a year, one of the lowest in the world, but this figure is based mostly on reported sales of exports and largely ignores the unregistered sale of foods, locally produced alcoholic beverages, diamonds, ivory, bushmeat, and traditional medicine. For most Central Africans, the informal economy of the CAR is more important than the formal economy.[citation needed] Export trade is hindered by poor economic development and the country's landlocked position.[citation needed]

What is the unregistered sale of foods hindered by?

QUES: The U.S. dollar was created by the Constitution and defined by the Coinage Act of 1792. It specified a "dollar" to be based in the Spanish milled dollar and of 371 grains and 4 sixteenths part of a grain of pure or 416 grains (27.0 g) of standard silver and an "eagle" to be 247 and 4 eighths of a grain or 270 grains (17 g) of gold (again depending on purity). The choice of the value 371 grains arose from Alexander Hamilton's decision to base the new American unit on the average weight of a selection of worn Spanish dollars. Hamilton got the treasury to weigh a sample of Spanish dollars and the average weight came out to be 371 grains. A new Spanish dollar was usually about 377 grains in weight, and so the new U.S. dollar was at a slight discount in relation to the Spanish dollar.
What was the Hamilton based on?

Several Germanic tribes celebrated the returning of the daylight. A predominant deity was during this jubilee driven around in a noisy procession on a ship on wheels. The winter would be driven out, to make sure that fertility could return in spring. A central figure was possibly the fertility goddess Nerthus. Also there are some indications that the effigy of Nerthus or Freyr was placed on a ship with wheels and accompanied by a procession of people in animal disguise and men in women's clothes. Aboard the ship would the marriage of a man and woman be consummated as a fertility ritual.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Why was the winter driven out?
Ah, so.. to make sure that fertility could return in spring

Question: The legal administration of the death penalty in the United States is complex. Typically, it involves four critical steps: (1) sentencing, (2) direct review, (3) state collateral review, and (4) federal habeas corpus. Recently, a narrow and final fifth level of process (5) the Section 1983 challenge has become increasingly important. (Clemency or pardon, through which the Governor or President of the jurisdiction can unilaterally reduce or abrogate a death sentence, is an executive rather than judicial process.) The number of new death sentences handed down peaked in 19951996 (309). There were 73 new death sentences handed down in 2014, the lowest number since 1973 (44).
Try to answer this question if possible: How many death sentences were issued in the period 1995-1996?
Answer: 309

Context and question: Yale has numerous athletic facilities, including the Yale Bowl (the nation's first natural "bowl" stadium, and prototype for such stadiums as the Los Angeles Memorial Coliseum and the Rose Bowl), located at The Walter Camp Field athletic complex, and the Payne Whitney Gymnasium, the second-largest indoor athletic complex in the world.

Yale also maintains the Gales Ferry site where the heavyweight men's team trains for the Yale-Harvard Boat Race.
How much did the Richard Gilder Boathouse cost to construct?
Answer:
$7.5 million
