Problem: Indigenous peoples of the Americas:

Many pre-Columbian civilizations established characteristics and hallmarks which included permanent or urban settlements, agriculture, civic and monumental architecture, and complex societal hierarchies. Some of these civilizations had long faded by the time of the first significant European and African arrivals (ca. late 15thearly 16th centuries), and are known only through oral history and through archaeological investigations. Others were contemporary with this period, and are also known from historical accounts of the time. A few, such as the Mayan, Olmec, Mixtec, and Nahua peoples, had their own written records. However, the European colonists of the time worked to eliminate non-Christian beliefs, and Christian pyres destroyed many pre-Columbian written records. Only a few documents remained hidden and survived, leaving contemporary historians with glimpses of ancient culture and knowledge.

What gave today's historians a glimpse of the culture and knowledge of the indigenous civilizations?

A: a few documents

Problem: United States presidential election, 2004:

On March 10, 2004, Bush officially clinched the number of delegates needed to be nominated at the 2004 Republican National Convention in New York City. Bush accepted the nomination on September 2, 2004, and selected Vice President Dick Cheney as his running mate. (In New York, the ticket was also on the ballot as candidates of the Conservative Party of New York State.) During the convention and throughout the campaign, Bush focused on two themes: defending America against terrorism and building an ownership society. The ownership society included allowing people to invest some of their Social Security in the stock market, increasing home and stock ownership, and encouraging more people to buy their own health insurance.

When did Dick Cheney get enough delegates to be nominated at the RNC?

Problem: Serbo-Croatian:

The opinion of the majority of Croatian linguists[citation needed] is that there has never been a Serbo-Croatian language, but two different standard languages that overlapped sometime in the course of history. However, Croatian linguist Snjezana Kordic has been leading an academic discussion on that issue in the Croatian journal Knjizevna republika from 2001 to 2010. In the discussion, she shows that linguistic criteria such as mutual intelligibility, huge overlap in linguistic system, and the same dialectic basis of standard language provide evidence that Croatian, Serbian, Bosnian and Montenegrin are four national variants of the pluricentric Serbo-Croatian language. Igor Mandic states: "During the last ten years, it has been the longest, the most serious and most acrid discussion () in 21st-century Croatian culture". Inspired by that discussion, a monograph on language and nationalism has been published.

What has been published based on mutual intelligibility?

A: unanswerable

Problem: CBC Television:

One of the most popular shows on CBC Television is the weekly Saturday night broadcast of NHL hockey games, Hockey Night in Canada. It has been televised by the network since 1952. During the NHL lockout and subsequent cancellation of the 2004-2005 hockey season, CBC instead aired various recent and classic movies, branded as Movie Night in Canada, on Saturday nights. Many cultural groups criticized this and suggested the CBC air games from minor hockey leagues; the CBC responded that most such broadcast rights were already held by other groups, but it did base each Movie Night broadcast from a different Canadian hockey venue. Other than hockey, CBC Sports properties include Toronto Raptors basketball, Toronto FC Soccer, and various other amateur and professional events.

What did CBC air during the NHL lockout?

A:
various recent and classic movies
