Problem: In the Papal States, which existed until 1870, Jews were required to live only in specified neighborhoods called ghettos. In the 19th and (before the end of World War II) 20th centuries, the Roman Catholic Church adhered to a distinction between "good antisemitism" and "bad antisemitism". The "bad" kind promoted hatred of Jews because of their descent. This was considered un-Christian because the Christian message was intended for all of humanity regardless of ethnicity; anyone could become a Christian. The "good" kind criticized alleged Jewish conspiracies to control newspapers, banks, and other institutions, to care only about accumulation of wealth, etc.
In the Papal States, what is the name for the specified neighborhoods where Jews were required to live?
The answer is the following: ghettos

Problem: In 1827, Hungarian physicist Anyos Jedlik started experimenting with electromagnetic coils. After Jedlik solved the technical problems of the continuous rotation with the invention of the commutator, he called his early devices "electromagnetic self-rotors". Although they were used only for instructional purposes, in 1828 Jedlik demonstrated the first device to contain the three main components of practical DC motors: the stator, rotor and commutator. The device employed no permanent magnets, as the magnetic fields of both the stationary and revolving components were produced solely by the currents flowing through their windings.
What did Jedlik's improved device eliminate the need for?
The answer is the following: permanent magnets

Problem: Albon Man, a New York lawyer, started Electro-Dynamic Light Company in 1878 to exploit his patents and those of William Sawyer. Weeks later the United States Electric Lighting Company was organized. This company didn't made their first commercial installation of incandescent lamps until the fall of 1880 at the Mercantile Safe Deposit Company in New York City, about six months after the Edison incandescent lamps had been installed on the Columbia. Hiram S. Maxim was the chief engineer at the United States Electric Lighting Company.
Which company was organized first, Electro-Dynamic Light Company or United States Electric Lighting Company?
The answer is the following: Electro-Dynamic Light Company

Problem: Transparency International, an anti-corruption NGO, pioneered this field with the CPI, first released in 1995. This work is often credited with breaking a taboo and forcing the issue of corruption into high level development policy discourse. Transparency International currently publishes three measures, updated annually: a CPI (based on aggregating third-party polling of public perceptions of how corrupt different countries are); a Global Corruption Barometer (based on a survey of general public attitudes toward and experience of corruption); and a Bribe Payers Index, looking at the willingness of foreign firms to pay bribes. The Corruption Perceptions Index is the best known of these metrics, though it has drawn much criticism and may be declining in influence. In 2013 Transparency International published a report on the "Government Defence Anti-corruption Index". This index evaluates the risk of corruption in countries' military sector.
Which index studies the correlation of corruption and military in a country?
The answer is the following:
Government Defence Anti-corruption Index
