Debutantes wore full court dress, with three tall ostrich feathers in their hair.

Problem: Given the question: Extract the answer to the question from the following context. Question: What is the fastest these elevators go? Context: Passenger elevators capacity is related to the available floor space. Generally passenger elevators are available in capacities from 500 to 2,700 kg (1,0006,000 lb) in 230 kg (500 lb) increments.[citation needed] Generally passenger elevators in buildings of eight floors or fewer are hydraulic or electric, which can reach speeds up to 1 m/s (200 ft/min) hydraulic and up to 152 m/min (500 ft/min) electric. In buildings up to ten floors, electric and gearless elevators are likely to have speeds up to 3 m/s (500 ft/min), and above ten floors speeds range 3 to 10 m/s (5002,000 ft/min).[citation needed]

Problem: Extract the answer to the question from the following context. Question: Near which river did Charles keep his troops? Context: 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.

Danube
