PROBLEM: An advantage of the universal motor is that AC supplies may be used on motors which have some characteristics more common in DC motors, specifically high starting torque and very compact design if high running speeds are used. The negative aspect is the maintenance and short life problems caused by the commutator. Such motors are used in devices such as food mixers and power tools which are used only intermittently, and often have high starting-torque demands. Multiple taps on the field coil provide (imprecise) stepped speed control. Household blenders that advertise many speeds frequently combine a field coil with several taps and a diode that can be inserted in series with the motor (causing the motor to run on half-wave rectified AC). Universal motors also lend themselves to electronic speed control and, as such, are an ideal choice for devices like domestic washing machines. The motor can be used to agitate the drum (both forwards and in reverse) by switching the field winding with respect to the armature.

SOLUTION: What kind of motor can employ both AC and DC?

PROBLEM: Though much of Enlightenment political thought was dominated by social contract theorists, both David Hume and Adam Ferguson criticized this camp. Hume's essay Of the Original Contract argues that governments derived from consent are rarely seen, and civil government is grounded in a ruler's habitual authority and force. It is precisely because of the ruler's authority over-and-against the subject, that the subject tacitly consents; Hume says that the subjects would "never imagine that their consent made him sovereign", rather the authority did so. Similarly, Ferguson did not believe citizens built the state, rather polities grew out of social development. In his 1767 An Essay on the History of Civil Society, Ferguson uses the four stages of progress, a theory that was very popular in Scotland at the time, to explain how humans advance from a hunting and gathering society to a commercial and civil society without "signing" a social contract.

SOLUTION: In what work did Ferguson explain how humans advanced from a hunting and gathering society to a commercial and civil society without "signing" a social contract?

PROBLEM: The Montana Territory was formed on April 26, 1864, when the U.S. passed the Organic Act. Schools started forming in the area before it was officially a territory as families started settling into the area. The first schools were subscription schools that typically held in the teacher's home. The first formal school on record was at Fort Owen in Bitterroot valley in 1862. The students were Indian children and the children of Fort Owen employees. The first school term started in early winter and only lasted until February 28. Classes were taught by Mr. Robinson. Another early subscription school was started by Thomas Dimsdale in Virginia City in 1863. In this school students were charged $1.75 per week. The Montana Territorial Legislative Assembly had its inaugural meeting in 1864. The first legislature authorized counties to levy taxes for schools, which set the foundations for public schooling. Madison County was the first to take advantage of the newly authorized taxes and it formed fhe first public school in Virginia City in 1886. The first school year was scheduled to begin in January 1866, but severe weather postponed its opening until March. The first school year ran through the summer and didn't end until August 17. One of the first teachers at the school was Sarah Raymond. She was a 25-year-old woman who had traveled to Virginia City via wagon train in 1865. To become a certified teacher, Raymond took a test in her home and paid a $6 fee in gold dust to obtain a teaching certificate. With the help of an assistant teacher, Mrs. Farley, Raymond was responsible for teaching 50 to 60 students each day out of the 81 students enrolled at the school. Sarah Raymond was paid at a rate of $125 per month, and Mrs. Farley was paid $75 per month. There were no textbooks used in the school. In their place was an assortment of books brought in by various emigrants. Sarah quit teaching the following year, but would later become the Madison County superintendent of schools.

SOLUTION:
When was the Montana Territory formed?
