Context and question: In 1875, blacks made up 57% of the city's population, and 73% of Charleston County. With leadership by members of the antebellum free black community, historian Melinda Meeks Hennessy described the community as "unique" in being able to defend themselves without provoking "massive white retaliation", as occurred in numerous other areas during Reconstruction. In the 1876 election cycle, two major riots between black Republicans and white Democrats occurred in the city, in September and the day after the election in November, as well as a violent incident in Cainhoy at an October joint discussion meeting.
What percentage of Charleston County's was black in 1857?
Answer: unanswerable
Context and question: In a WRIM, the rotor winding is made of many turns of insulated wire and is connected to slip rings on the motor shaft. An external resistor or other control devices can be connected in the rotor circuit. Resistors allow control of the motor speed, although significant power is dissipated in the external resistance. A converter can be fed from the rotor circuit and return the slip-frequency power that would otherwise be wasted back into the power system through an inverter or separate motor-generator.
What can a resistor control?
Answer: motor speed
Context and question: Internationally, Nigeria is infamous for a form of bank fraud dubbed 419, a type of advance fee fraud (named after Section 419 of the Nigerian Penal Code) along with the "Nigerian scam", a form of confidence trick practised by individuals and criminal syndicates. These scams involve a complicit Nigerian bank (the laws being set up loosely to allow it) and a scammer who claims to have money he needs to obtain from that bank. The victim is talked into exchanging bank account information on the premise that the money will be transferred to him, and then he'll get to keep a cut. In reality, money is taken out instead, and/or large fees (which seem small in comparison with the imaginary wealth he awaits) are deducted. In 2003, the Nigerian Economic and Financial Crimes Commission (or EFCC) was created, ostensibly to combat this and other forms of organised financial crime.
When was the Nigerian EFCC created?
Answer:
2003
