Problem: Religion in ancient Rome:

In the early stages of the First Punic War (264 BC) the first known Roman gladiatorial munus was held, described as a funeral blood-rite to the manes of a Roman military aristocrat. The gladiator munus was never explicitly acknowledged as a human sacrifice, probably because death was not its inevitable outcome or purpose. Even so, the gladiators swore their lives to the infernal gods, and the combat was dedicated as an offering to the di manes or other gods. The event was therefore a sacrificium in the strict sense of the term, and Christian writers later condemned it as human sacrifice.

How was the gladiatorial combat described?

A: funeral blood-rite

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The 100th meridian roughly corresponds with the line that divides the Great Plains into an area that receive 20 inches (510 millimetres) or more of rainfall per year and an area that receives less than 20 in (510 mm). In this context, the High Plains, as well as Southern Alberta, south-western Saskatchewan and Eastern Montana are mainly semi hot steppe land and are generally characterised by rangeland or marginal farmland. The region (especially the High Plains) is periodically subjected to extended periods of drought; high winds in the region may then generate devastating dust storms. The eastern Great Plains near the eastern boundary falls in the humid subtropical climate zone in the southern areas, and the northern and central areas fall in the humid continental climate.
What would be a state that lies east of the Great Plains?
A: unanswerable

Context and question: To begin with, England had no permanent home stadium. They joined FIFA in 1906 and played their first ever games against countries other than the Home Nations on a tour of Central Europe in 1908. Wembley Stadium was opened in 1923 and became their home ground. The relationship between England and FIFA became strained, and this resulted in their departure from FIFA in 1928, before they rejoined in 1946. As a result, they did not compete in a World Cup until 1950, in which they were beaten in a 10 defeat by the United States, failing to get past the first round in one of the most embarrassing defeats in the team's history.
In what year did the United States join FIFA?
Answer: unanswerable

Question: Detroit has a Mexican-American population. In the early 20th century thousands of Mexicans came to Detroit to work in agricultural, automotive, and steel jobs. During the Mexican Repatriation of the 1930s many Mexicans in Detroit were willingly repatriated or forced to repatriate. By the 1940s the Mexican community began to settle what is now Mexicantown. The population significantly increased in the 1990s due to immigration from Jalisco. In 2010 Detroit had 48,679 Hispanics, including 36,452 Mexicans. The number of Hispanics was a 70% increase from the number in 1990.
Is there an answer to this question: When did Mexicantown start to grow?

Answer: 1940s

QUES: In July 1943, as a result of the American Federation of Musicians boycott of US recording studios, the a cappella vocal group The Song Spinners had a best-seller with "Comin' In On A Wing And A Prayer". In the 1950s several recording groups, notably The Hi-Los and the Four Freshmen, introduced complex jazz harmonies to a cappella performances. The King's Singers are credited with promoting interest in small-group a cappella performances in the 1960s. In 1983 an a cappella group known as The Flying Pickets had a Christmas 'number one' in the UK with a cover of Yazoo's (known in the US as Yaz) "Only You". A cappella music attained renewed prominence from the late 1980s onward, spurred by the success of Top 40 recordings by artists such as The Manhattan Transfer, Bobby McFerrin, Huey Lewis and the News, All-4-One, The Nylons, Backstreet Boys and Boyz II Men.[citation needed]
