Problem: Professional wrestling:

Fans of professional wrestling have their own subculture, comparable to those of science fiction, video games, or comic books (in some cases, the "fandoms" overlap; in recent years, some professional wrestlers, particularly those who nurture an anti-establishment rebel persona, such as CM Punk, have made guest appearances at comic book conventions). Those who are interested in the backstage occurrences, future storylines, and reasonings behind company decisions read newsletters written by journalists with inside ties to the wrestling industry. These "rags" or "dirt sheets" have expanded into the Internet, where their information can be dispensed on an up-to-the-minute basis. Some have expanded into radio shows.

Where have some wrestlers appeared?

Problem: To counter the trend towards low-density suburban residential growth, the government began a series of controversial public housing projects in the inner city by the Housing Commission of Victoria, which resulted in demolition of many neighbourhoods and a proliferation of high-rise towers. In later years, with the rapid rise of motor vehicle ownership, the investment in freeway and highway developments greatly accelerated the outward suburban sprawl and declining inner city population. The Bolte government sought to rapidly accelerate the modernisation of Melbourne. Major road projects including the remodelling of St Kilda Junction, the widening of Hoddle Street and then the extensive 1969 Melbourne Transportation Plan changed the face of the city into a car-dominated environment.
Did the rapid rise of motor vehicle ownership and highway developments lead to an increasing or declining inner city population?

Answer: declining

Context and question: The production arm of the studio still struggled. While there were to be a few hits like The Killers (1946) and The Naked City (1948), Universal-International's new theatrical films often met with disappointing response at the box office. By the late 1940s, Goetz was out, and the studio returned to low-budget films. The inexpensive Francis (1950), the first film of a series about a talking mule and Ma and Pa Kettle (1949), part of a series, became mainstays of the company. Once again, the films of Abbott and Costello, including Abbott and Costello Meet Frankenstein (1948), were among the studio's top-grossing productions. But at this point Rank lost interest and sold his shares to the investor Milton Rackmil, whose Decca Records would take full control of Universal in 1952. Besides Abbott and Costello, the studio retained the Walter Lantz cartoon studio, whose product was released with Universal-International's films.
Who left Universal in 1940?
Answer: unanswerable

Beyonce's first solo recording was a feature on Jay Z's "'03 Bonnie & Clyde" that was released in October 2002, peaking at number four on the U.S. Billboard Hot 100 chart. Her first solo album Dangerously in Love was released on June 24, 2003, after Michelle Williams and Kelly Rowland had released their solo efforts. The album sold 317,000 copies in its first week, debuted atop the Billboard 200, and has since sold 11 million copies worldwide. The album's lead single, "Crazy in Love", featuring Jay Z, became Beyonce's first number-one single as a solo artist in the US. The single "Baby Boy" also reached number one, and singles, "Me, Myself and I" and "Naughty Girl", both reached the top-five. The album earned Beyonce a then record-tying five awards at the 46th Annual Grammy Awards; Best Contemporary R&B Album, Best Female R&B Vocal Performance for "Dangerously in Love 2", Best R&B Song and Best Rap/Sung Collaboration for "Crazy in Love", and Best R&B Performance by a Duo or Group with Vocals for "The Closer I Get to You" with Luther Vandross.
