Problem: Simple stepper motor drivers entirely energize or entirely de-energize the field windings, leading the rotor to "cog" to a limited number of positions; more sophisticated drivers can proportionally control the power to the field windings, allowing the rotors to position between the cog points and thereby rotate extremely smoothly. This mode of operation is often called microstepping. Computer controlled stepper motors are one of the most versatile forms of positioning systems, particularly when part of a digital servo-controlled system.
With what other device are stepper motors most versatile?
The answer is the following: digital servo-controlled system

Problem: In the early 21st century the Cypriot economy has diversified and become prosperous. However, in 2012 it became affected by the Eurozone financial and banking crisis. In June 2012, the Cypriot government announced it would need 1.8 billion in foreign aid to support the Cyprus Popular Bank, and this was followed by Fitch downgrading Cyprus's credit rating to junk status. Fitch said Cyprus would need an additional 4 billion to support its banks and the downgrade was mainly due to the exposure of Bank of Cyprus, Cyprus Popular Bank and Hellenic Bank, Cyprus's three largest banks, to the Greek financial crisis.
How much many did the Cypriot government initially announce it needed?
The answer is the following: 1.8 billion

Problem: The Jamahiriya's radical direction earned the government many enemies. In February 1978, Gaddafi discovered that his head of military intelligence was plotting to kill him, and began to increasingly entrust security to his Qaddadfa tribe. Many who had seen their wealth and property confiscated turned against the administration, and a number of western-funded opposition groups were founded by exiles. Most prominent was the National Front for the Salvation of Libya (NFSL), founded in 1981 by Mohammed Magariaf, which orchestrated militant attacks against Libya's government, while another, al-Borkan, began killing Libyan diplomats abroad. Following Gaddafi's command to kill these "stray dogs", under Colonel Younis Bilgasim's leadership, the Revolutionary Committees set up overseas branches to suppress counter-revolutionary activity, assassinating various dissidents. Although nearby nations like Syria also used hit squads, Gaddafi was unusual in publicly bragging about his administration's use of them; in June 1980, he ordered all dissidents to return home or be "liquidated wherever you are."
Who founded the NFSL?
The answer is the following:
Mohammed Magariaf
