Problem: Please answer a question about the following article about Electric motor:
When optimally designed within a given core saturation constraint and for a given active current (i.e., torque current), voltage, pole-pair number, excitation frequency (i.e., synchronous speed), and air-gap flux density, all categories of electric motors or generators will exhibit virtually the same maximum continuous shaft torque (i.e., operating torque) within a given air-gap area with winding slots and back-iron depth, which determines the physical size of electromagnetic core. Some applications require bursts of torque beyond the maximum operating torque, such as short bursts of torque to accelerate an electric vehicle from standstill. Always limited by magnetic core saturation or safe operating temperature rise and voltage, the capacity for torque bursts beyond the maximum operating torque differs significantly between categories of electric motors or generators.
Whate decides the size of an electromagnetic core?
A: air-gap area with winding slots and back-iron depth
Problem: Please answer a question about the following article about United Nations Population Fund:
But Amnesty International found no evidence that UNFPA had supported the coercion. A 2001 study conducted by the pro-life Population Research Institute (PRI) falsely claimed that the UNFPA shared an office with the Chinese family planning officials who were carrying out forced abortions. "We located the family planning offices, and in that family planning office, we located the UNFPA office, and we confirmed from family planning officials there that there is no distinction between what the UNFPA does and what the Chinese Family Planning Office does," said Scott Weinberg, a spokesman for PRI. However, United Nations Members disagreed and approved UNFPA's new country program me in January 2006. The more than 130 members of the "Group of 77" developing countries in the United Nations expressed support for the UNFPA programmes. In addition, speaking for European democracies -- Norway, Denmark, Sweden, Finland, the Netherlands, France, Belgium, Switzerland and Germany -- the United Kingdom stated, "UNFPA's activities in China, as in the rest of the world, are in strict conformity with the unanimously adopted Programme of Action of the ICPD, and play a key role in supporting our common endeavor, the promotion and protection of all human rights and fundamental freedoms."
In January 2006, who approved UNFPA's new country programme?
A: United Nations Members
Problem: Please answer a question about the following article about Protestantism:
The necessity and inerrancy were well-established ideas, garnering little criticism, though they later came under debate from outside during the Enlightenment. The most contentious idea at the time though was the notion that anyone could simply pick up the Bible and learn enough to gain salvation. Though the reformers were concerned with ecclesiology (the doctrine of how the church as a body works), they had a different understanding of the process in which truths in scripture were applied to life of believers, compared to the Catholics' idea that certain people within the church, or ideas that were old enough, had a special status in giving understanding of the text.
What is the term for how the church as a whole works?
A: ecclesiology
Problem: Please answer a question about the following article about Middle Ages:
The first years of the 14th century were marked by famines, culminating in the Great Famine of 131517. The causes of the Great Famine included the slow transition from the Medieval Warm Period to the Little Ice Age, which left the population vulnerable when bad weather caused crop failures. The years 131314 and 131721 were excessively rainy throughout Europe, resulting in widespread crop failures. The climate changewhich resulted in a declining average annual temperature for Europe during the 14th centurywas accompanied by an economic downturn.
In what century did the European average annual temperature decrease?
A:
14th
