Problem: Videoconferencing:

In the increasingly globalized film industry, videoconferencing has become useful as a method by which creative talent in many different locations can collaborate closely on the complex details of film production. For example, for the 2013 award-winning animated film Frozen, Burbank-based Walt Disney Animation Studios hired the New York City-based husband-and-wife songwriting team of Robert Lopez and Kristen Anderson-Lopez to write the songs, which required two-hour-long transcontinental videoconferences nearly every weekday for about 14 months.

In what industry has using different locations become useful?

A: unanswerable


Problem: A brief shoot at London's City Hall was filmed on 18 April 2015, while Mendes was on location. On 17 May 2015 filming took place on the Thames in London. Stunt scenes involving Craig and Seydoux on a speedboat as well as a low flying helicopter near Westminster Bridge were shot at night, with filming temporarily closing both Westminster and Lambeth Bridges. Scenes were also shot on the river near MI6's headquarters at Vauxhall Cross. The crew returned to the river less than a week later to film scenes solely set on Westminster Bridge. The London Fire Brigade was on set to simulate rain as well as monitor smoke used for filming. Craig, Seydoux, and Waltz, as well as Harris and Fiennes, were seen being filmed. Prior to this, scenes involving Fiennes were shot at a restaurant in Covent Garden. Filming then took place in Trafalgar Square. In early June, the crew, as well as Craig, Seydoux, and Waltz, returned to the Thames for a final time to continue filming scenes previously shot on the river.

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Athanasius's episcopate began on 9 May 328 as the Alexandrian Council elected Athanasius to succeed the aged Alexander. That council also denounced various heresies and schisms, many of which continued to preoccupy his 45-year-long episcopate (c. 8 June 328 – 2 May 373). Patriarch Athanasius spent over 17 years in five exiles ordered by four different Roman Emperors, not counting approximately six more incidents in which Athanasius fled Alexandria to escape people seeking to take his life. This gave rise to the expression "Athanasius contra mundum" or "Athanasius against the world". However, during his first years as bishop, Athanasius visited the churches of his territory, which at that time included all of Egypt and Libya. He established contacts with the hermits and monks of the desert, including Pachomius, which proved very valuable to him over the years. Shortly thereafter, Athanasius became occupied with the theological disputes against Arians within the Byzantine Empire that would occupy much of his life.
How many exiles did he endure?
A: five exiles


Context and question: In 1985, the combination of the Mac, Apple's LaserWriter printer, and Mac-specific software like Boston Software's MacPublisher and Aldus PageMaker enabled users to design, preview, and print page layouts complete with text and graphics—an activity to become known as desktop publishing. Initially, desktop publishing was unique to the Macintosh, but eventually became available for other platforms. Later, applications such as Macromedia FreeHand, QuarkXPress, and Adobe's Photoshop and Illustrator strengthened the Mac's position as a graphics computer and helped to expand the emerging desktop publishing market.
What did desktop publishing enable users to do?
Answer: design, preview, and print page layouts complete with text and graphics


Question: The creation of modern-day Eritrea is a result of the incorporation of independent, distinct kingdoms and sultanates (for example, Medri Bahri and the Sultanate of Aussa) eventually resulting in the formation of Italian Eritrea. In 1947 Eritrea became part of a federation with Ethiopia, the Federation of Ethiopia and Eritrea. Subsequent annexation into Ethiopia led to the Eritrean War of Independence, ending with Eritrean independence following a referendum in April 1993. Hostilities between Eritrea and Ethiopia persisted, leading to the Eritrean–Ethiopian War of 1998–2000 and further skirmishes with both Djibouti and Ethiopia.
Is there an answer to this question: In what year was the Sultanate of Aussa founded?

Answer: unanswerable


Problem: Richmond, Virginia:

Three years later, as March 1865 ended, the Confederate capitol became indefensible. On March 25, Confederate General John B. Gordon's desperate attack on Fort Stedman east of Petersburg failed. On April 1, General Philip Sheridan, assigned to interdict the Southside Railroad, met brigades commanded by George Pickett at the Five Forks junction, smashing them, taking thousands of prisoners, and encouraging General Grant to order a general advance. When the Union Sixth Corps broke through Confederate lines on Boydton Plank Road south of Petersburg, Confederate casualties exceeded 5000, or about a tenth of Lee's defending army. General Lee then informed Jefferson Davis that he was about to evacuate Richmond.

In what month of 1865 was Richmond judged to be no longer able to be defended?
---
A:
March
