Problem: Please answer a question about the following article about Armenians:
Armenians have had a presence in the Armenian Highland for over four thousand years, since the time when Hayk, the legendary patriarch and founder of the first Armenian nation, led them to victory over Bel of Babylon. Today, with a population of 3.5 million, they not only constitute an overwhelming majority in Armenia, but also in the disputed region of Nagorno-Karabakh. Armenians in the diaspora informally refer to them as Hayastantsis (Հայաստանցի), meaning those that are from Armenia (that is, those born and raised in Armenia). They, as well as the Armenians of Iran and Russia speak the Eastern dialect of the Armenian language. The country itself is secular as a result of Soviet domination, but most of its citizens identify themselves as Apostolic Armenian Christian.
How long have Armenians lived in the highlands?
A: over four thousand years
Problem: Please answer a question about the following article about Neptune:
The formation of the ice giants, Neptune and Uranus, has proven difficult to model precisely. Current models suggest that the matter density in the outer regions of the Solar System was too low to account for the formation of such large bodies from the traditionally accepted method of core accretion, and various hypotheses have been advanced to explain their formation. One is that the ice giants were not formed by core accretion but from instabilities within the original protoplanetary disc and later had their atmospheres blasted away by radiation from a nearby massive OB star.
If Neptune was formed from instabilities within the original protoplanetary disc, what was it not formed by?
A: core accretion
Problem: Please answer a question about the following article about Religion in ancient Rome:
In the wake of the Republic's collapse, state religion had adapted to support the new regime of the emperors. Augustus, the first Roman emperor, justified the novelty of one-man rule with a vast program of religious revivalism and reform. Public vows formerly made for the security of the republic now were directed at the wellbeing of the emperor. So-called "emperor worship" expanded on a grand scale the traditional Roman veneration of the ancestral dead and of the Genius, the divine tutelary of every individual. Imperial cult became one of the major ways in which Rome advertised its presence in the provinces and cultivated shared cultural identity and loyalty throughout the Empire. Rejection of the state religion was tantamount to treason. This was the context for Rome's conflict with Christianity, which Romans variously regarded as a form of atheism and novel superstitio.
What did the Romans use as a means of expanding their rule throughout the empire?
A: Imperial cult
Problem: Please answer a question about the following article about Electric motor:
Stepper motors can be rotated to a specific angle in discrete steps with ease, and hence stepper motors are used for read/write head positioning in computer floppy diskette drives. They were used for the same purpose in pre-gigabyte era computer disk drives, where the precision and speed they offered was adequate for the correct positioning of the read/write head of a hard disk drive. As drive density increased, the precision and speed limitations of stepper motors made them obsolete for hard drives—the precision limitation made them unusable, and the speed limitation made them uncompetitive—thus newer hard disk drives use voice coil-based head actuator systems. (The term "voice coil" in this connection is historic; it refers to the structure in a typical (cone type) loudspeaker. This structure was used for a while to position the heads. Modern drives have a pivoted coil mount; the coil swings back and forth, something like a blade of a rotating fan. Nevertheless, like a voice coil, modern actuator coil conductors (the magnet wire) move perpendicular to the magnetic lines of force.)
What do newer computer drives use instead of stepper motors?
A:
voice coil-based head actuator systems
