Problem: Hellenistic period:

Under Ptolemy II, Callimachus, Apollonius of Rhodes, Theocritus and a host of other poets made the city a center of Hellenistic literature. Ptolemy himself was eager to patronise the library, scientific research and individual scholars who lived on the grounds of the library. He and his successors also fought a series of wars with the Seleucids, known as the Syrian wars, over the region of Coele-Syria. Ptolemy IV won the great battle of Raphia (217 BCE) against the Seleucids, using native Egyptians trained as phalangites. However these Egyptian soldiers revolted, eventually setting up a native breakaway Egyptian state in the Thebaid between 205-186/5 BCE, severely weakening the Ptolemaic state.

Who won the great battle of Raphia?

A: Ptolemy IV


Problem: Infection:

Thus, the technological ability to detect any infectious agent rapidly and specifically are currently available. The only remaining blockades to the use of PCR as a standard tool of diagnosis are in its cost and application, neither of which is insurmountable. The diagnosis of a few diseases will not benefit from the development of PCR methods, such as some of the clostridial diseases (tetanus and botulism). These diseases are fundamentally biological poisonings by relatively small numbers of infectious bacteria that produce extremely potent neurotoxins. A significant proliferation of the infectious agent does not occur, this limits the ability of PCR to detect the presence of any bacteria.

Which blockades to use PCR are currently insurmountable?

A: unanswerable


Problem: Gamal Abdel Nasser:

The Free Officers' intention was not to install themselves in government, but to re-establish a parliamentary democracy. Nasser did not believe that a low-ranking officer like himself (a lieutenant colonel) would be accepted by the Egyptian people, and so selected General Naguib to be his "boss" and lead the coup in name. The revolution they had long sought was launched on 22 July and was declared a success the next day. The Free Officers seized control of all government buildings, radio stations, and police stations, as well as army headquarters in Cairo. While many of the rebel officers were leading their units, Nasser donned civilian clothing to avoid detection by royalists and moved around Cairo monitoring the situation. In a move to stave off foreign intervention two days before the revolution, Nasser had notified the American and British governments of his intentions, and both had agreed not to aid Farouk. Under pressure from the Americans, Nasser had agreed to exile the deposed king with an honorary ceremony.

What day did the revolution begin?
---
A: 22 July


Problem: Biodiversity:

On the other hand, changes through the Phanerozoic correlate much better with the hyperbolic model (widely used in population biology, demography and macrosociology, as well as fossil biodiversity) than with exponential and logistic models. The latter models imply that changes in diversity are guided by a first-order positive feedback (more ancestors, more descendants) and/or a negative feedback arising from resource limitation. Hyperbolic model implies a second-order positive feedback. The hyperbolic pattern of the world population growth arises from a second-order positive feedback between the population size and the rate of technological growth. The hyperbolic character of biodiversity growth can be similarly accounted for by a feedback between diversity and community structure complexity. The similarity between the curves of biodiversity and human population probably comes from the fact that both are derived from the interference of the hyperbolic trend with cyclical and stochastic dynamics.

What can be accounted for by a feedback between diversity and macrosociology trends?
