Problem: Royal Dutch Shell:

Traditionally, Shell was a heavily decentralised business worldwide (especially in the downstream) with companies in over 100 countries, each of which operated with a high degree of independence. The upstream tended to be far more centralised with much of the technical and financial direction coming from the central offices in The Hague. Nevertheless, there were very large "exploration and production" companies in a few major oil and gas production centres such as the United Kingdom (Shell Expro, a Joint Venture with Exxon), Nigeria, Brunei, and Oman.

How many countries were large exploration and production companies in?

A: unanswerable

Problem: The high-speed observation deck elevators accelerate to a world-record certified speed of 1,010 metres per minute (61 km/h) in 16 seconds, and then it slows down for arrival with subtle air pressure sensations. The door opens after 37 seconds from the 5th floor. Special features include aerodynamic car and counterweights, and cabin pressure control to help passengers adapt smoothly to pressure changes. The downwards journey is completed at a reduced speed of 600 meters per minute, with the doors opening at the 52nd second.
This speed holds what record?

The Dominican friars quickly spread, including to England, where they appeared in Oxford in 1221. In the 13th century the order reached all classes of Christian society, fought heresy, schism, and paganism by word and book, and by its missions to the north of Europe, to Africa, and Asia passed beyond the frontiers of Christendom. Its schools spread throughout the entire Church; its doctors wrote monumental works in all branches of knowledge, including the extremely important Albertus Magnus and Thomas Aquinas. Its members included popes, cardinals, bishops, legates, inquisitors, confessors of princes, ambassadors, and paciarii (enforcers of the peace decreed by popes or councils). The order was appointed by Pope Gregory IX the duty to carry out the Inquisition. In his Papal Bull Ad extirpanda of 1252, Pope Innocent IV authorised the Dominicans' use of torture under prescribed circumstances.
Who appointed the Benedictine Order to begin the inquisition?
A: unanswerable

Context and question: The troops were reembarked and moved to the Bay of St. Lunaire in Brittany where, on 3 September, they were landed to operate against St. Malo; however, this action proved impractical. Worsening weather forced the two armies to separate: the ships sailed for the safer anchorage of St. Cast, while the army proceeded overland. The tardiness of Bligh in moving his forces allowed a French force of 10,000 from Brest to catch up with him and open fire on the reembarkation troops. A rear-guard of 1,400 under General Dury held off the French while the rest of the army embarked. They could not be saved; 750, including Dury, were killed and the rest captured.
How did the British army escape
Answer: A rear-guard of 1,400 under General Dury held off the French while the rest of the army embarked

Question: The Eastern Han, also known as the Later Han, formally began on 5 August 25, when Liu Xiu became Emperor Guangwu of Han. During the widespread rebellion against Wang Mang, the state of Goguryeo was free to raid Han's Korean commanderies; Han did not reaffirm its control over the region until AD 30. The Trung Sisters of Vietnam rebelled against Han in AD 40. Their rebellion was crushed by Han general Ma Yuan (d. AD 49) in a campaign from AD 4243. Wang Mang renewed hostilities against the Xiongnu, who were estranged from Han until their leader Bi (), a rival claimant to the throne against his cousin Punu (), submitted to Han as a tributary vassal in AD 50. This created two rival Xiongnu states: the Southern Xiongnu led by Bi, an ally of Han, and the Northern Xiongnu led by Punu, an enemy of Han.
Is there an answer to this question: Who was the leader of the Xiongnu?

Answer: Bi
