Problem: Theologus Autodidactus, written by the Arabian polymath Ibn al-Nafis (12131288), is the first example of a science fiction novel. It deals with various science fiction elements such as spontaneous generation, futurology, the end of the world and doomsday, resurrection, and the afterlife. Rather than giving supernatural or mythological explanations for these events, Ibn al-Nafis attempted to explain these plot elements using the scientific knowledge of biology, astronomy, cosmology and geology known in his time. Ibn al-Nafis' fiction explained Islamic religious teachings via science and Islamic philosophy.

Problem: In brief, there is disagreement among historical analysts as to the exact time period when the minority leadership emerged officially as a party position. Nonetheless, it seems safe to conclude that the position emerged during the latter part of the 19th century, a period of strong party organization and professional politicians. This era was "marked by strong partisan attachments, resilient patronage-based party organizations, and...high levels of party voting in Congress." Plainly, these were conditions conducive to the establishment of a more highly differentiated House leadership structure.
When was House leadership structure first established?

Problem: Each republican magistrate held certain constitutional powers. Only the People of Rome (both plebeians and patricians) had the right to confer these powers on any individual magistrate. The most powerful constitutional power was imperium. Imperium was held by both consuls and praetors. Imperium gave a magistrate the authority to command a military force. All magistrates also had the power of coercion. This was used by magistrates to maintain public order. While in Rome, all citizens had a judgement against coercion. This protection was called provocatio (see below). Magistrates also had both the power and the duty to look for omens. This power would often be used to obstruct political opponents.
Who had the right to grant powers to a magistrate?

People of Rome
