The Han dynasty was an age of economic prosperity and saw a significant growth of the money economy first established during the Zhou dynasty (c. 1050256 BC). The coinage issued by the central government mint in 119 BC remained the standard coinage of China until the Tang dynasty (618907 AD). The period saw a number of limited institutional innovations. To pay for its military campaigns and the settlement of newly conquered frontier territories, the government nationalized the private salt and iron industries in 117 BC, but these government monopolies were repealed during the Eastern Han period. Science and technology during the Han period saw significant advances, including papermaking, the nautical steering rudder, the use of negative numbers in mathematics, the raised-relief map, the hydraulic-powered armillary sphere for astronomy, and a seismometer employing an inverted pendulum.
In what year did the central government issue coins?
A: 119 BC

While the decision (with four dissents) ultimately upheld the state law allowing the funding of transportation of students to religious schools, the majority opinion (by Justice Hugo Black) and the dissenting opinions (by Justice Wiley Blount Rutledge and Justice Robert H. Jackson) each explicitly stated that the Constitution has erected a "wall between church and state" or a "separation of Church from State": their disagreement was limited to whether this case of state funding of transportation to religious schools breached that wall. Rutledge, on behalf of the four dissenting justices, took the position that the majority had indeed permitted a violation of the wall of separation in this case: "Neither so high nor so impregnable today as yesterday is the wall raised between church and state by Virginia's great statute of religious freedom and the First Amendment, now made applicable to all the states by the Fourteenth." Writing separately, Justice Jackson argued that "[T]here are no good grounds upon which to support the present legislation. In fact, the undertones of the opinion, advocating complete and uncompromising separation of Church from State, seem utterly discordant with its conclusion yielding support to their commingling in educational matters."
What was the state allowed to continue to fund?
A: transportation of students to religious schools

Virgil's biographical tradition is thought to depend on a lost biography by Varius, Virgil's editor, which was incorporated into the biography by Suetonius and the commentaries of Servius and Donatus, the two great commentators on Virgil's poetry. Although the commentaries no doubt record much factual information about Virgil, some of their evidence can be shown to rely on inferences made from his poetry and allegorizing; thus, Virgil's biographical tradition remains problematic.
What was Varius most famous for?
A:
