Input: Electric motor
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.

What component of a universal motor is most likely to fail?
Output: commutator

Input: Article: In the north, substantial efforts were made against Newcastle-upon-Tyne and Sunderland, which were large ports on the English east coast. On 9 April 1941 Luftflotte 2 dropped 150 tons of high explosives and 50,000 incendiaries from 120 bombers in a five-hour attack. Sewer, rail, docklands, and electric installations were damaged. In Sunderland on 25 April, Luftflotte 2 sent 60 bombers which dropped 80 tons of high explosive and 9,000 incendiaries. Much damage was done. A further attack on the Clyde, this time at Greenock, took place on 6 and 7 May. However, as with the attacks in the south, the Germans failed to prevent maritime movements or cripple industry in the regions.

Now answer this question: Sunderland saw how many incendiaries used against it on 25 April?

Output: 9,000 incendiaries

Article: Many scholars (including Makdisi) have argued that early medieval universities were influenced by the religious madrasahs in Al-Andalus, the Emirate of Sicily, and the Middle East (during the Crusades). Other scholars see this argument as overstated. Lowe and Yasuhara have recently drawn on the well-documented influences of scholarship from the Islamic world on the universities of Western Europe to call for a reconsideration of the development of higher education, turning away from a concern with local institutional structures to a broader consideration within a global context.

Question: Al-Andalus was an Emirate of which entity?
Ans: Sicily

Here is a question about this article: Racial discrimination continued to be enacted in new laws in the 20th century, for instance the one-drop rule was enacted in Virginia's 1924 Racial Integrity Law and in other southern states, in part influenced by the popularity of eugenics and ideas of racial purity. People buried fading memories that many whites had multiracial ancestry. Many families were multiracial. Similar laws had been proposed but not passed in the late nineteenth century in South Carolina and Virginia, for instance. After regaining political power in Southern states by disenfranchising blacks, white Democrats passed laws to impose Jim Crow and racial segregation to restore white supremacy. They maintained these until forced to change in the 1960s and after by enforcement of federal legislation authorizing oversight of practices to protect the constitutional rights of African Americans and other minority citizens.
What is the answer to this question: Why were laws limiting people of color passed?
****
So... to restore white supremacy

The problem: Answer a question about this article:
Ranthambore National Park is known worldwide for its tiger population and is considered by both wilderness lovers and photographers as one of the best place in India to spot tigers. At one point, due to poaching and negligence, tigers became extinct at Sariska, but five tigers have been relocated there. Prominent among the wildlife sanctuaries are Mount Abu Sanctuary, Bhensrod Garh Sanctuary, Darrah Sanctuary, Jaisamand Sanctuary, Kumbhalgarh Wildlife Sanctuary, Jawahar Sagar sanctuary, and Sita Mata Wildlife Sanctuary.
Ranthamb National Park is known by photographers as what?
****
The answer: one of the best place in India to spot tigers

The Marshall Islands, officially the Republic of the Marshall Islands (Marshallese: Aolepan Aorokin Majel),[note 1] is an island country located near the equator in the Pacific Ocean, slightly west of the International Date Line. Geographically, the country is part of the larger island group of Micronesia. The country's population of 53,158 people (at the 2011 Census) is spread out over 29 coral atolls, comprising 1,156 individual islands and islets. The islands share maritime boundaries with the Federated States of Micronesia to the west, Wake Island to the north,[note 2] Kiribati to the south-east, and Nauru to the south. About 27,797 of the islanders (at the 2011 Census) live on Majuro, which contains the capital.
In what ocean are the Marshall Islands located?
