Problem: John von Neumann:

Such strategies, which minimize the maximum loss for each player, are called optimal. Von Neumann showed that their minimaxes are equal (in absolute value) and contrary (in sign). Von Neumann improved and extended the minimax theorem to include games involving imperfect information and games with more than two players, publishing this result in his 1944 Theory of Games and Economic Behavior (written with Oskar Morgenstern). Morgenstern wrote a paper on game theory and thought he would show it to von Neumann because of his interest in the subject. He read it and said to Morgenstern that he should put more in it. This was repeated a couple of times, and then von Neumann became a coauthor and the paper became 100 pages long. Then it became a book. The public interest in this work was such that The New York Times ran a front-page story. In this book, von Neumann declared that economic theory needed to use functional analytic methods, especially convex sets and topological fixed-point theorem, rather than the traditional differential calculus, because the maximum-operator did not preserve differentiable functions.

What is optimal strategy?
---
A: minimize the maximum loss for each player


Problem: The most obvious function of clothing is to improve the comfort of the wearer, by protecting the wearer from the elements. In hot climates, clothing provides protection from sunburn or wind damage, while in cold climates its thermal insulation properties are generally more important. Shelter usually reduces the functional need for clothing. For example, coats, hats, gloves, and other superficial layers are normally removed when entering a warm home, particularly if one is residing or sleeping there. Similarly, clothing has seasonal and regional aspects, so that thinner materials and fewer layers of clothing are generally worn in warmer seasons and regions than in colder ones.
In what type of climate does clothing protect against sunburn and wind damage?
---
Answer: hot

Health care delivery in Nigeria is a concurrent responsibility of the three tiers of government in the country, and the private sector. Nigeria has been reorganising its health system since the Bamako Initiative of 1987, which formally promoted community-based methods of increasing accessibility of drugs and health care services to the population, in part by implementing user fees. The new strategy dramatically increased accessibility through community-based healthcare reform, resulting in more efficient and equitable provision of services. A comprehensive approach strategy was extended to all areas of health care, with subsequent improvement in the health care indicators and improvement in health care efficiency and cost.
When did Nigeria start reorganizing its healthcare system?
A: 1987


Context and question: Widespread drought in North China, combined with the imperialist designs of European powers and the instability of the Qing government, created conditions that led to the emergence of the Righteous and Harmonious Fists, or "Boxers." In 1900, local groups of Boxers proclaiming support for the Qing dynasty murdered foreign missionaries and large numbers of Chinese Christians, then converged on Beijing to besiege the Foreign Legation Quarter. A coalition of European, Japanese, and Russian armies (the Eight-Nation Alliance) then entered China without diplomatic notice, much less permission. Cixi declared war on all of these nations, only to lose control of Beijing after a short, but hard-fought campaign. She fled to Xi'an. The victorious allies drew up scores of demands on the Qing government, including compensation for their expenses in invading China and execution of complicit officials.
What was another name for the Boxers?
Answer: Righteous and Harmonious Fists


Question: The proximity of the Palace of Westminster did not extend to providing monks or abbots with high royal connections; in social origin the Benedictines of Westminster were as modest as most of the order. The abbot remained Lord of the Manor of Westminster as a town of two to three thousand persons grew around it: as a consumer and employer on a grand scale the monastery helped fuel the town economy, and relations with the town remained unusually cordial, but no enfranchising charter was issued during the Middle Ages. The abbey built shops and dwellings on the west side, encroaching upon the sanctuary.[citation needed]
Is there an answer to this question: What did the abbot remain as a town built inside the abbey?

Answer: unanswerable


QUES: One of the few city states who managed to maintain full independence from the control of any Hellenistic kingdom was Rhodes. With a skilled navy to protect its trade fleets from pirates and an ideal strategic position covering the routes from the east into the Aegean, Rhodes prospered during the Hellenistic period. It became a center of culture and commerce, its coins were widely circulated and its philosophical schools became one of the best in the mediterranean. After holding out for one year under siege by Demetrius Poliorcetes (304-305 BCE), the Rhodians built the Colossus of Rhodes to commemorate their victory. They retained their independence by the maintenance of a powerful navy, by maintaining a carefully neutral posture and acting to preserve the balance of power between the major Hellenistic kingdoms.

What did Rhodians build to commemorate their victory over Demetrius Poliorcetes?
What is the answer?
ANS:
Colossus of Rhodes
