Problem: Federalism:

In Brazil, the fall of the monarchy in 1889 by a military coup d'etat led to the rise of the presidential system, headed by Deodoro da Fonseca. Aided by well-known jurist Ruy Barbosa, Fonseca established federalism in Brazil by decree, but this system of government would be confirmed by every Brazilian constitution since 1891, although some of them would distort some of the federalist principles. The 1937 Constitution, for example, granted the federal government the authority to appoint State Governors (called interventors) at will, thus centralizing power in the hands of President Getulio Vargas. Brazil also uses the Fonseca system to regulate interstate trade. Brazil is one of the biggest federal governments.

Problem: Religion in ancient Rome:

Imported mystery religions, which offered initiates salvation in the afterlife, were a matter of personal choice for an individual, practiced in addition to carrying on one's family rites and participating in public religion. The mysteries, however, involved exclusive oaths and secrecy, conditions that conservative Romans viewed with suspicion as characteristic of "magic", conspiratorial (coniuratio), or subversive activity. Sporadic and sometimes brutal attempts were made to suppress religionists who seemed to threaten traditional morality and unity, as with the senate's efforts to restrict the Bacchanals in 186 BC.

What did the mysteries seem to threaten that made the Romans occasionally attempt to ban them?

A: morality and unity

Problem: Gramophone record:

Flexible or so-called "unbreakable" records made of unusual materials were introduced by a number of manufacturers at various times during the 78 rpm era. In the UK, Nicole records, made of celluloid or a similar substance coated onto a cardboard core disc, were produced for a few years beginning in 1904, but they suffered from an exceptionally high level of surface noise. In the United States, Columbia Records introduced flexible, fiber-cored "Marconi Velvet Tone Record" pressings in 1907, but the advantages and longevity of their relatively noiseless surfaces depended on the scrupulous use of special gold-plated Marconi Needles and the product was not a success. Thin, flexible plastic records such as the German Phonycord and the British Filmophone and Goodson records appeared around 1930 but also did not last long. The contemporary French Pathe Cellodiscs, made of a very thin black plastic, which uncannily resembles the vinyl "sound sheet" magazine inserts of the 19651985 era, were similarly short-lived. In the US, Hit of the Week records, made of a patented translucent plastic called Durium coated on a heavy brown paper base, were introduced in early 1930. A new issue came out every week and they were sold at newsstands like a weekly magazine. Although inexpensive and commercially successful at first, they soon fell victim to the Great Depression and production in the US ended in 1932. Related Durium records continued to be made somewhat later in the UK and elsewhere, and as remarkably late as 1950 in Italy, where the name "Durium" survived far into the LP era as a trademark on ordinary vinyl records. Despite all these attempts at innovation, shellac compounds continued to be used for the overwhelming majority of commercial 78 rpm records during the lifetime of the format.

What was a major downfall of the success of Durium records?
---
A: Great Depression

Problem: Edmund Burke:

Burke's religious writing comprises published works and commentary on the subject of religion. Burke's religious thought was grounded in the belief that religion is the foundation of civil society. He sharply criticised deism and atheism, and emphasised Christianity as a vehicle of social progress. Born in Ireland to a Catholic mother and a Protestant father, Burke vigorously defended the Anglican Church, but also demonstrated sensitivity to Catholic concerns. He linked the conservation of a state (established) religion with the preservation of citizens' constitutional liberties and highlighted Christianity's benefit not only to the believer's soul, but also to political arrangements.

What did Burke believe was the foundation of religion?
