Problem: On 16 March 1934, President Franklin D. Roosevelt signed the Migratory Bird Hunting Stamp Act, which requires an annual stamp purchase by all hunters over the age of sixteen. The stamps are created on behalf of the program by the US Postal Service and depict wildlife artwork chosen through an annual contest. They play an important role in habitat conservation because ninety-eight percent of all funds generated by their sale go directly toward the purchase or lease of wetland habitat for protection in the National Wildlife Refuge System.[citation needed] In addition to waterfowl, it is estimated that one third of the nation's endangered species seek food and shelter in areas protected using Duck Stamp funds.[citation needed]
How much of the nation's endangered species is it estimated benefits from the protection afford by the Duck Stamp funds?
The answer is the following: one third

Problem: Between 1847 and 1850, when Blore was building the new east wing, the Brighton Pavilion was once again plundered of its fittings. As a result, many of the rooms in the new wing have a distinctly oriental atmosphere. The red and blue Chinese Luncheon Room is made up from parts of the Brighton Banqueting and Music Rooms with a large oriental chimney piece sculpted by Richard Westmacott. The Yellow Drawing Room has wallpaper supplied in 1817 for the Brighton Saloon, and a chimney piece which is a European vision of how the Chinese chimney piece may appear. It has nodding mandarins in niches and fearsome winged dragons, designed by Robert Jones.
The red and blue Chinese Luncheon Room has what as a main feature?
The answer is the following: large oriental chimney piece

Problem: Early research into circadian rhythms suggested that most people preferred a day closer to 25 hours when isolated from external stimuli like daylight and timekeeping. However, this research was faulty because it failed to shield the participants from artificial light. Although subjects were shielded from time cues (like clocks) and daylight, the researchers were not aware of the phase-delaying effects of indoor electric lights.[dubious discuss] The subjects were allowed to turn on light when they were awake and to turn it off when they wanted to sleep. Electric light in the evening delayed their circadian phase.[citation needed] A more stringent study conducted in 1999 by Harvard University estimated the natural human rhythm to be closer to 24 hours, 11 minutes: much closer to the solar day but still not perfectly in sync.
What did electric lighting in the evening do to the test subjects circadian phase?
The answer is the following: delayed

Problem: The Aeronautics Branch was renamed the Bureau of Air Commerce in 1934 to reflect its enhanced status within the Department. As commercial flying increased, the Bureau encouraged a group of airlines to establish the first three centers for providing air traffic control (ATC) along the airways. In 1936, the Bureau itself took over the centers and began to expand the ATC system. The pioneer air traffic controllers used maps, blackboards, and mental calculations to ensure the safe separation of aircraft traveling along designated routes between cities.
When did the Buerau take over and begin to expant the ATC system?
The answer is the following:
1936
