[Q]: I know that the answer to the question "What was the other half of roman population alongside the non-citizens?" is in "Rome's government, politics and religion were dominated by an educated, male, landowning military aristocracy. Approximately half Rome's population were slave or free non-citizens. Most others were plebeians, the lowest class of Roman citizens. Less than a quarter of adult males had voting rights; far fewer could actually exercise them. Women had no vote. However, all official business was conducted under the divine gaze and auspices, in the name of the senate and people of Rome. "In a very real sense the senate was the caretaker of the Romans' relationship with the divine, just as it was the caretaker of their relationship with other humans".". Can you tell me what it is?

[A]: citizens

[Q]: I know that the answer to the question "What was the logic behind the leap year put forth in 1560?" is in "Ancient tables provided the sun's mean longitude. Christopher Clavius, the architect of the Gregorian calendar, noted that the tables agreed neither on the time when the sun passed through the vernal equinox nor on the length of the mean tropical year. Tycho Brahe also noticed discrepancies. The Gregorian leap year rule (97 leap years in 400 years) was put forward by Petrus Pitatus of Verona in 1560. He noted that it is consistent with the tropical year of the Alfonsine tables and with the mean tropical year of Copernicus (De revolutionibus) and Reinhold (Prutenic tables). The three mean tropical years in Babylonian sexagesimals as the excess over 365 days (the way they would have been extracted from the tables of mean longitude) were 14,33,9,57 (Alphonsine), 14,33,11,12 (Copernicus) and 14,33,9,24 (Reinhold). All values are the same to two places (14:33) and this is also the mean length of the Gregorian year. Thus Pitatus' solution would have commended itself to the astronomers.".

[Q]: I know that the answer to the question "Which position came into existence later, DNI or president?" is in "The FBI director is responsible for the day-to-day operations at the FBI. Along with his deputies, the director makes sure cases and operations are handled correctly. The director also is in charge of making sure the leadership in any one of the FBI field offices is manned with qualified agents. Before the Intelligence Reform and Terrorism Prevention Act was passed in the wake of the September 11 attacks, the FBI director would directly brief the President of the United States on any issues that arise from within the FBI. Since then, the director now reports to the Director of National Intelligence (DNI), who in turn reports to the President.". Can you tell me what it is?
