Problem: Exhibition game:

True exhibition games between opposing colleges at the highest level do not exist in college football; due to the importance of opinion polling in the top level of college football, even exhibition games would not truly be exhibitions because they could influence the opinions of those polled. Intramural games are possible because a team playing against itself leaves little ability for poll participants to make judgments, and at levels below the Football Bowl Subdivision (FBS), championships are decided by objective formulas and thus those teams can play non-league games without affecting their playoff hopes.

What kind of polling is not important in college football?

A: unanswerable


Problem: The most obvious link between modern and ancient Greeks is their language, which has a documented tradition from at least the 14th century BC to the present day, albeit with a break during the Greek Dark Ages (lasting from the 11th to the 8th century BC). Scholars compare its continuity of tradition to Chinese alone. Since its inception, Hellenism was primarily a matter of common culture and the national continuity of the Greek world is a lot more certain than its demographic. Yet, Hellenism also embodied an ancestral dimension through aspects of Athenian literature that developed and influenced ideas of descent based on autochthony. During the later years of the Eastern Roman Empire, areas such as Ionia and Constantinople experienced a Hellenic revival in language, philosophy, and literature and on classical models of thought and scholarship. This revival provided a powerful impetus to the sense of cultural affinity with ancient Greece and its classical heritage. The cultural changes undergone by the Greeks are, despite a surviving common sense of ethnicity, undeniable. At the same time, the Greeks have retained their language and alphabet, certain values and cultural traditions, customs, a sense of religious and cultural difference and exclusion, (the word barbarian was used by 12th-century historian Anna Komnene to describe non-Greek speakers), a sense of Greek identity and common sense of ethnicity despite the global political and social changes of the past two millennia.
What is the easiest connection between the Greeks of old and those of today ?

The city has a unique status in Brazil, as it is an administrative division rather than a legal municipality like other cities in Brazil. The name 'Brasília' is commonly used as a synonym for the Federal District through synecdoche; However, the Federal District is composed of 31 administrative regions, only one of which is Brasília proper, with a population of 209,926 in a 2011 survey; Demographic publications generally do not make this distinction and list the population of Brasília as synonymous with the population of the Federal District, considering the whole of it as its metropolitan area. The city was one of the main host cities of the 2014 FIFA World Cup. Additionally, Brasília hosted the 2013 FIFA Confederations Cup.
What was Brasil a main administrative division of in 2014?

Context and question: By 6000 BCE predynastic Egyptians in the southwestern corner of Egypt were herding cattle and constructing large buildings. Subsistence in organized and permanent settlements in predynastic Egypt by the middle of the 6th millennium BCE centered predominantly on cereal and animal agriculture: cattle, goats, pigs and sheep. Metal objects replaced prior ones of stone. Tanning of animal skins, pottery and weaving were commonplace in this era also. There are indications of seasonal or only temporary occupation of the Al Fayyum in the 6th millennium BCE, with food activities centering on fishing, hunting and food-gathering. Stone arrowheads, knives and scrapers from the era are commonly found. Burial items included pottery, jewelry, farming and hunting equipment, and assorted foods including dried meat and fruit. Burial in desert environments appears to enhance Egyptian preservation rites, and dead were buried facing due west.
What items replaced previously items made of stone?
Answer: Metal objects


Question: Towards the end of the 1990s and into the 2000s, producers such as Daft Punk, Stardust, Cassius, St. Germain and DJ Falcon began producing a new sound out of Paris's house scene.

By combining the harder-edged-yet-soulful philosophy of Chicago house with the melodies of obscure funk, state-of-the-art production techniques and the sound of analog synthesizers, they began to create the standards that would shape all house music.
Is there an answer to this question: What did Chicago's house scene lead to?
