Problem: Beyoncé:

Described as being "sexy, seductive and provocative" when performing on stage, Beyoncé has said that she originally created the alter ego "Sasha Fierce" to keep that stage persona separate from who she really is. She described Sasha as being "too aggressive, too strong, too sassy [and] too sexy", stating, "I'm not like her in real life at all." Sasha was conceived during the making of "Crazy in Love", and Beyoncé introduced her with the release of her 2008 album I Am... Sasha Fierce. In February 2010, she announced in an interview with Allure magazine that she was comfortable enough with herself to no longer need Sasha Fierce. However, Beyoncé announced in May 2012 that she would bring her back for her Revel Presents: Beyoncé Live shows later that month.

What year did Beyonce do away with Sasha Fierce?

A: 2010


Problem: Many mechanical aids to calculation and measurement were constructed for astronomical and navigation use. The planisphere was a star chart invented by Abū Rayhān al-Bīrūnī in the early 11th century. The astrolabe was invented in the Hellenistic world in either the 1st or 2nd centuries BC and is often attributed to Hipparchus. A combination of the planisphere and dioptra, the astrolabe was effectively an analog computer capable of working out several different kinds of problems in spherical astronomy. An astrolabe incorporating a mechanical calendar computer and gear-wheels was invented by Abi Bakr of Isfahan, Persia in 1235. Abū Rayhān al-Bīrūnī invented the first mechanical geared lunisolar calendar astrolabe, an early fixed-wired knowledge processing machine with a gear train and gear-wheels, circa 1000 AD.

Context and question: The earliest record of the location appears as São João on a Portuguese map by Pedro Reinel in 1519. When John Rut visited St. John's in 1527 he found Norman, Breton and Portuguese ships in the harbour. On 3 August 1527, Rut wrote a letter to King Henry on the findings of his voyage to North America; this was the first known letter sent from North America. St. Jehan is shown on Nicholas Desliens' world map of 1541 and San Joham is found in João Freire's Atlas of 1546. It was during this time that Water Street was first developed, making it the oldest street in North America.[dubious – discuss]

Question: Virgil's biographical tradition is thought to depend on a lost biography by Varius, Virgil's editor, which was incorporated into the biography by Suetonius and the commentaries of Servius and Donatus, the two great commentators on Virgil's poetry. Although the commentaries no doubt record much factual information about Virgil, some of their evidence can be shown to rely on inferences made from his poetry and allegorizing; thus, Virgil's biographical tradition remains problematic.
Is there an answer to this question: Who was Virgil's editor?

Answer: Varius
