On April 4, 2008, Beyonce married Jay Z. She publicly revealed their marriage in a video montage at the listening party for her third studio album, I Am... Sasha Fierce, in Manhattan's Sony Club on October 22, 2008. I Am... Sasha Fierce was released on November 18, 2008 in the United States. The album formally introduces Beyonce's alter ego Sasha Fierce, conceived during the making of her 2003 single "Crazy in Love", selling 482,000 copies in its first week, debuting atop the Billboard 200, and giving Beyonce her third consecutive number-one album in the US. The album featured the number-one song "Single Ladies (Put a Ring on It)" and the top-five songs "If I Were a Boy" and "Halo". Achieving the accomplishment of becoming her longest-running Hot 100 single in her career, "Halo"'s success in the US helped Beyonce attain more top-ten singles on the list than any other woman during the 2000s. It also included the successful "Sweet Dreams", and singles "Diva", "Ego", "Broken-Hearted Girl" and "Video Phone". The music video for "Single Ladies" has been parodied and imitated around the world, spawning the "first major dance craze" of the Internet age according to the Toronto Star. The video has won several awards, including Best Video at the 2009 MTV Europe Music Awards, the 2009 Scottish MOBO Awards, and the 2009 BET Awards. At the 2009 MTV Video Music Awards, the video was nominated for nine awards, ultimately winning three including Video of the Year. Its failure to win the Best Female Video category, which went to American country pop singer Taylor Swift's "You Belong with Me", led to Kanye West interrupting the ceremony and Beyonce improvising a re-presentation of Swift's award during her own acceptance speech. In March 2009, Beyonce embarked on the I Am... World Tour, her second headlining worldwide concert tour, consisting of 108 shows, grossing $119.5 million.

When interviewed for Mojo magazine the band said the most amazing sight at Live Aid was to see the audience clapping to "Radio Ga Ga". Brian May stated: "I'd never seen anything like that in my life and it wasn't calculated either. We understood our audience and played to them but that was one of those weird accidents because of the (music) video. I remember thinking 'oh great, they've picked it up' and then I thought 'this is not a Queen audience'. This is a general audience who've bought tickets before they even knew we were on the bill. And they all did it. How did they know? Nobody told them to do it."

Application of electric motors revolutionized industry. Industrial processes were no longer limited by power transmission using line shafts, belts, compressed air or hydraulic pressure. Instead every machine could be equipped with its own electric motor, providing easy control at the point of use, and improving power transmission efficiency. Electric motors applied in agriculture eliminated human and animal muscle power from such tasks as handling grain or pumping water. Household uses of electric motors reduced heavy labor in the home and made higher standards of convenience, comfort and safety possible. Today, electric motors stand for more than half of the electric energy consumption in the US.
In what domain did electric motors reduce reliance on humans and animals?
****
The answer:
agriculture
