Problem: Korean War:

The on-again, off-again armistice negotiations continued for two years, first at Kaesong, on the border between North and South Korea, and then at the neighbouring village of Panmunjom. A major, problematic negotiation point was prisoner of war (POW) repatriation. The PVA, KPA, and UN Command could not agree on a system of repatriation because many PVA and KPA soldiers refused to be repatriated back to the north, which was unacceptable to the Chinese and North Koreans. In the final armistice agreement, signed on 27 July 1953, a Neutral Nations Repatriation Commission, under the chairman Indian General K. S. Thimayya, was set up to handle the matter.

When was the armistice agreement finally signed?

A: 27 July 1953

Problem: Robert S. Wood has argued that the United States is a model for the world in terms of how a separation of church and stateno state-run or state-established churchis good for both the church and the state, allowing a variety of religions to flourish. Speaking at the Toronto-based Center for New Religions, Wood said that the freedom of conscience and assembly allowed under such a system has led to a "remarkable religiosity" in the United States that isn't present in other industrialized nations. Wood believes that the U.S. operates on "a sort of civic religion," which includes a generally-shared belief in a creator who "expects better of us." Beyond that, individuals are free to decide how they want to believe and fill in their own creeds and express their conscience. He calls this approach the "genius of religious sentiment in the United States."
What does having no state-run or state-established allow a variety of non-religions to do?

In 1904, a British expedition to Tibet, spurred in part by a fear that Russia was extending its power into Tibet as part of The Great Game, invaded the country, hoping that negotiations with the 13th Dalai Lama would be more effective than with Chinese representatives. When the British-led invasion reached Tibet on December 12, 1903, an armed confrontation with the ethnic Tibetans resulted in the Massacre of Chumik Shenko, which resulted in 600 fatalities amongst the Tibetan forces, compared to only 12 on the British side. Afterwards, in 1904 Francis Younghusband imposed a treaty known as the Treaty of Lhasa, which was subsequently repudiated and was succeeded by a 1906 treaty signed between Britain and China.
Who did the 12th Dalai Lama negotiate with?
A: unanswerable

Context and question: Ducks are medium-sized aquatic birds with broad bills, eyes on the side of the head, fairly long necks, short legs set far back on the body, and webbed feet. Males, known as drakes, are often larger than females (simply known as ducks) and are differently coloured in some breeds. Domestic ducks are omnivores, eating a variety of animal and plant materials such as aquatic insects, molluscs, worms, small amphibians, waterweeds, and grasses. They feed in shallow water by dabbling, with their heads underwater and their tails upended. Most domestic ducks are too heavy to fly, and they are social birds, preferring to live and move around together in groups. They keep their plumage waterproof by preening, a process that spreads the secretions of the preen gland over their feathers.
What do you call a male duck?
Answer: drakes

Question: On May 15, 2013, Resident Commissioner Pierluisi introduced H.R. 2000 to Congress to "set forth the process for Puerto Rico to be admitted as a state of the Union," asking for Congress to vote on ratifying Puerto Rico as the 51st state. On February 12, 2014, Senator Martin Heinrich introduced a bill in the US Senate.

The cathedral has a heliometer (solar "observatory") of 1690, one of a number built in Italy in the 17th and 18th centuries. The device itself is quite simple: a tiny hole in one of the minor domes acts as pinhole camera, projecting an image of the sun onto the floor at solar noon (12:00 in winter, 13:00 in summer). There is a bronze line, la Meridiana on the floor, running precisely N/S. The ends of the line mark the positions as at the summer and winter solstices; signs of the zodiac show the various other dates throughout the year.
What image is projected on the floor of the heliometer?
A:
the sun
