Problem: Northwestern University:

Sherman Ave is a humor website that formed in January 2011. The website often publishes content about Northwestern student life, and most of Sherman Ave's staffed writers are current Northwestern undergraduate students writing under pseudonyms. The publication is well known among students for its interviews of prominent campus figures, its "Freshman Guide", its live-tweeting coverage of football games, and its satiric campaign in autumn 2012 to end the Vanderbilt University football team's clubbing of baby seals.

What do many of the singers staffed by Sherman Ave write under?

A: unanswerable

Problem: Kinect is a "controller-free gaming and entertainment experience" for the Xbox 360. It was first announced on June 1, 2009 at the Electronic Entertainment Expo, under the codename, Project Natal. The add-on peripheral enables users to control and interact with the Xbox 360 without a game controller by using gestures, spoken commands and presented objects and images. The Kinect accessory is compatible with all Xbox 360 models, connecting to new models via a custom connector, and to older ones via a USB and mains power adapter. During their CES 2010 keynote speech, Robbie Bach and Microsoft CEO Steve Ballmer went on to say that Kinect will be released during the holiday period (NovemberJanuary) and it will work with every 360 console. Its name and release date of 2010-11-04 were officially announced on 2010-06-13, prior to Microsoft's press conference at E3 2010.
What prevents older models from working with the Kinect?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The role of the gas is to prevent evaporation of the filament, without introducing significant heat losses. For these properties, chemical inertness and high atomic or molecular weight is desirable. The presence of gas molecules knocks the liberated tungsten atoms back to the filament, reducing its evaporation and allowing it to be operated at higher temperature without reducing its life (or, for operating at the same temperature, prolongs the filament life). It however introduces heat losses (and therefore efficiency loss) from the filament, by heat conduction and heat convection.
What is the purpose of the gas in a light bulb?
A: to prevent evaporation of the filament, without introducing significant heat losses

Context and question: Goetz set out an ambitious schedule. Universal-International became responsible for the American distribution of Rank's British productions, including such classics as David Lean's Great Expectations (1946) and Laurence Olivier's Hamlet (1948). Broadening its scope further, Universal-International branched out into the lucrative non-theatrical field, buying a majority stake in home-movie dealer Castle Films in 1947, and taking the company over entirely in 1951. For three decades, Castle would offer "highlights" reels from the Universal film library to home-movie enthusiasts and collectors. Goetz licensed Universal's preUniversal-International film library to Jack Broeder's Realart Pictures for cinema re-release but Realart was not allowed to show the films on television.
What year was David Lean's Hamlet produced?
Answer: unanswerable

Question: Inscriptions have been found beneath many of the rock paintings, but archaeologists have so far been unable to decipher this form of ancient writing. During the Stone age, the Doian culture and the Hargeisan culture flourished here with their respective industries and factories.
Is there an answer to this question: During what period did the Doian culture thrive?

Answer: the Stone age

Problem: Northwestern University:

Two annual productions are especially notable: the Waa-Mu show, and the Dolphin show. Waa-Mu is an original musical, written and produced almost entirely by students. Children's theater is represented on campus by Griffin's Tale and Purple Crayon Players. Its umbrella organizationthe Student Theatre Coalition, or StuCo, organizes nine student theatre companies, multiple performance groups and more than sixty independent productions each year. Many Northwestern alumni have used these productions as stepping stones to successful television and film careers. Chicago's Lookingglass Theatre Company, for example, which began life in the Great Room in Jones Residential College, was founded in 1988 by several alumni, including David Schwimmer; in 2011, it won the Regional Tony Award.

Which theater company was founded by several Northwestern alumni in 1988?

A:
Chicago's Lookingglass
