Problem: Electric motor:

A servo system differs from some stepper motor applications in that the position feedback is continuous while the motor is running; a stepper system relies on the motor not to "miss steps" for short term accuracy, although a stepper system may include a "home" switch or other element to provide long-term stability of control. For instance, when a typical dot matrix computer printer starts up, its controller makes the print head stepper motor drive to its left-hand limit, where a position sensor defines home position and stops stepping. As long as power is on, a bidirectional counter in the printer's microprocessor keeps track of print-head position.

 A stepper system's motor is unrelied on to not do what?

Problem: History of India:

The Arthashastra and the Edicts of Ashoka are the primary written records of the Mauryan times. Archaeologically, this period falls into the era of Northern Black Polished Ware (NBPW). The Mauryan Empire was based on a modern and efficient economy and society. However, the sale of merchandise was closely regulated by the government. Although there was no banking in the Mauryan society, usury was customary. A significant amount of written records on slavery are found, suggesting a prevalence thereof. During this period, a high quality steel called Wootz steel was developed in south India and was later exported to China and Arabia.

What is the archaeological period of the Mauryan Empire?
---
A: Northern Black Polished Ware


Problem: Namibia:

Up to 1990, English, German and Afrikaans were official languages. Long before Namibia's independence from South Africa, SWAPO was of the opinion that the country should become officially monolingual, choosing this approach in contrast to that of its neighbour South Africa (which granted all 11 of its major languages official status), which was seen by them as "a deliberate policy of ethnolinguistic fragmentation." Consequently, SWAPO instituted English as the sole official language of Namibia though only about 3% of the population speaks it as a home language. Its implementation is focused on the civil service, education and the broadcasting system. Some other languages have received semi-official recognition by being allowed as medium of instruction in primary schools. It is expected of private schools to follow the same policy as state schools, and "English language" is a compulsory subject. As in other postcolonial African societies, the push for monolingual instruction and policy has resulted in a high rate of school drop-outs and of individuals whose academic competence in any language is low.

There was a high rate of what due to monolingual instruction?
---
A: school drop-outs


Problem: CBC Television:

Until 1998, the network carried a variety of American programs in addition to its core Canadian programming, directly competing with private Canadian broadcasters such as CTV and Global. Since then, it has restricted itself to Canadian programs, a handful of British programs, and a few American movies and off-network repeats. Since this change, the CBC has sometimes struggled to maintain ratings comparable to those it achieved before 1995, although it has seen somewhat of a ratings resurgence in recent years. In the 2007-08 season, hit series such as Little Mosque on the Prairie and The Border helped the network achieve its strongest ratings performance in over half a decade.

What type of programming is permitted to be broadcast in Canada?

A:
unanswerable
