Problem: Nanjing:

Under the Qing dynasty (16441911), the Nanjing area was known as Jiangning () and served as the seat of government for the Viceroy of Liangjiang. It had been visited by the Kangxi and Qianlong emperors a number of times on their tours of the southern provinces. Nanjing was invaded by British troops during the close of the First Opium War, which was ended by the Treaty of Nanjing in 1842. As the capital of the brief-lived rebel Taiping Heavenly Kingdom (founded by the Taiping rebels in the mid-19th century, Nanjing was known as Tianjing (, "Heavenly Capital" or "Capital of Heaven").

What emperors visited Nanjing more than once?
---
A: the Kangxi and Qianlong emperors

Problem: Anthropology:

Professional anthropological bodies often object to the use of anthropology for the benefit of the state. Their codes of ethics or statements may proscribe anthropologists from giving secret briefings. The Association of Social Anthropologists of the UK and Commonwealth (ASA) has called certain scholarship ethically dangerous. The AAA's current 'Statement of Professional Responsibility' clearly states that "in relation with their own government and with host governments ... no secret research, no secret reports or debriefings of any kind should be agreed to or given."

What permits antropologists to give secret briefings?
---
A: unanswerable

Problem: John von Neumann:

The reason for this is that a quantum disjunction, unlike the case for classical disjunction, can be true even when both of the disjuncts are false and this is, in turn, attributable to the fact that it is frequently the case, in quantum mechanics, that a pair of alternatives are semantically determinate, while each of its members are necessarily indeterminate. This latter property can be illustrated by a simple example. Suppose we are dealing with particles (such as electrons) of semi-integral spin (angular momentum) for which there are only two possible values: positive or negative. Then, a principle of indetermination establishes that the spin, relative to two different directions (e.g., x and y) results in a pair of incompatible quantities. Suppose that the state of a certain electron verifies the proposition "the spin of the electron in the x direction is positive." By the principle of indeterminacy, the value of the spin in the direction y will be completely indeterminate for . Hence, can verify neither the proposition "the spin in the direction of y is positive" nor the proposition "the spin in the direction of y is negative." Nevertheless, the disjunction of the propositions "the spin in the direction of y is positive or the spin in the direction of y is negative" must be true for . In the case of distribution, it is therefore possible to have a situation in which , while .

How can quantum disjuction be illustrated?
---
A: illustrated by a simple example

Problem: Political corruption:

In the context of political corruption, a bribe may involve a payment given to a government official in exchange of his use of official powers. Bribery requires two participants: one to give the bribe, and one to take it. Either may initiate the corrupt offering; for example, a customs official may demand bribes to let through allowed (or disallowed) goods, or a smuggler might offer bribes to gain passage. In some countries the culture of corruption extends to every aspect of public life, making it extremely difficult for individuals to operate without resorting to bribes. Bribes may be demanded in order for an official to do something he is already paid to do. They may also be demanded in order to bypass laws and regulations. In addition to their role in private financial gain, bribes are also used to intentionally and maliciously cause harm to another (i.e. no financial incentive).[citation needed] In some developing nations, up to half of the population has paid bribes during the past 12 months.

What do you call paying government officials to use their position in their office?
