During the 1930s, parts of the state began suffering the consequences of poor farming practices, extended drought and high winds. Known as the Dust Bowl, areas of Kansas, Texas, New Mexico and northwestern Oklahoma were hampered by long periods of little rainfall and abnormally high temperatures, sending thousands of farmers into poverty and forcing them to relocate to more fertile areas of the western United States. Over a twenty-year period ending in 1950, the state saw its only historical decline in population, dropping 6.9 percent as impoverished families migrated out of the state after the Dust Bowl.
When did the Dust Bowl begin?

The answer: 1930s

The problem: Answer a question about this article:
The senate's ultimate authority derived from the esteem and prestige of the senators. This esteem and prestige was based on both precedent and custom, as well as the caliber and reputation of the senators. The senate passed decrees, which were called senatus consulta. These were officially "advice" from the senate to a magistrate. In practice, however, they were usually followed by the magistrates. The focus of the Roman senate was usually directed towards foreign policy. Though it technically had no official role in the management of military conflict, the senate ultimately was the force that oversaw such affairs. The power of the senate expanded over time as the power of the legislative assemblies declined, and the senate took a greater role in ordinary law-making. Its members were usually appointed by Roman Censors, who ordinarily selected newly elected magistrates for membership in the senate, making the senate a partially elected body. During times of military emergency, such as the civil wars of the 1st century BC, this practice became less prevalent, as the Roman Dictator, Triumvir or the senate itself would select its members.
What governing Roman body would self-select their own members during times of great distress?
****
The answer: the senate itself would select its members

The Albanian bitumen extraction has a long history and was practiced in an organized way by the Romans. After centuries of silence, the first mentions of Albanian bitumen appeared only in 1868, when the Frenchman Coquand published the first geological description of the deposits of Albanian bitumen. In 1875, the exploitation rights were granted to the Ottoman government and in 1912, they were transferred to the Italian company Simsa. Since 1945, the mine was exploited by the Albanian government and from 2001 to date, the management passed to a French company, which organized the mining process for the manufacture of the natural bitumen on an industrial scale.
When were the first published reports of bitumen extraction in Albania?
****
The answer:
1868
