A defect in the human homologue of the Drosophila "period" gene was identified as a cause of the sleep disorder FASPS (Familial advanced sleep phase syndrome), underscoring the conserved nature of the molecular circadian clock through evolution. Many more genetic components of the biological clock are now known. Their interactions result in an interlocked feedback loop of gene products resulting in periodic fluctuations that the cells of the body interpret as a specific time of the day.[citation needed]
What is the Drosophila gene the cause of?
****
The answer: sleep disorder FASPS

In The New Yorker music critic Jody Rosen described Beyonce as "the most important and compelling popular musician of the twenty-first century..... the result, the logical end point, of a century-plus of pop." When The Guardian named her Artist of the Decade, Llewyn-Smith wrote, "Why Beyonce? [...] Because she made not one but two of the decade's greatest singles, with Crazy in Love and Single Ladies (Put a Ring on It), not to mention her hits with Destiny's Child; and this was the decade when singles particularly R&B singles regained their status as pop's favourite medium. [...] [She] and not any superannuated rock star was arguably the greatest live performer of the past 10 years." In 2013, Beyonce made the Time 100 list, Baz Luhrmann writing "no one has that voice, no one moves the way she moves, no one can hold an audience the way she does... When Beyonce does an album, when Beyonce sings a song, when Beyonce does anything, it's an event, and it's broadly influential. Right now, she is the heir-apparent diva of the USA the reigning national voice." In 2014, Beyonce was listed again on the Time 100 and also featured on the cover of the issue.
Who said that she is the reigning national voice?
****
The answer: Baz Luhrmann

Indigenous peoples of Brazil make up 0.4% of Brazil's population, or about 700,000 people, even though millions of Brazilians have some indigenous ancestry. Indigenous peoples are found in the entire territory of Brazil, although the majority of them live in Indian reservations in the North and Center-Western part of the country. On January 18, 2007, FUNAI reported that it had confirmed the presence of 67 different uncontacted tribes in Brazil, up from 40 in 2005. With this addition Brazil has now overtaken the island of New Guinea as the country having the largest number of uncontacted tribes.
How many different uncontacted tribes were confirmed in Brazil in 2007?
****
The answer: 67

The problem: Answer a question about this article:
Tennessee is known as the "Volunteer State", a nickname some claimed was earned during the War of 1812 because of the prominent role played by volunteer soldiers from Tennessee, especially during the Battle of New Orleans. Other sources differ on the origin of the state nickname; according to the Columbia Encyclopedia, the name refers to volunteers for the MexicanAmerican War. This explanation is more likely, because President Polk's call for 2,600 nationwide volunteers at the beginning of the Mexican-American War resulted in 30,000 volunteers from Tennessee alone, largely in response to the death of Davy Crockett and appeals by former Tennessee Governor and now Texas politician, Sam Houston.
Which major conflict that included the Battle of New Orleans is said to have given Tennessee its nickname?
****
The answer:
War of 1812
