Input: Article: Technological developments by videoconferencing developers in the 2010s have extended the capabilities of video conferencing systems beyond the boardroom for use with hand-held mobile devices that combine the use of video, audio and on-screen drawing capabilities broadcasting in real-time over secure networks, independent of location. Mobile collaboration systems now allow multiple people in previously unreachable locations, such as workers on an off-shore oil rig, the ability to view and discuss issues with colleagues thousands of miles away. Traditional videoconferencing system manufacturers have begun providing mobile applications as well, such as those that allow for live and still image streaming.

Now answer this question: In what decade did developers extend the capabilities of videoconferencing to more devices?

Output: the 2010s

Input: Article: Linking the information back together is the key to this system. In the relational model, some bit of information was used as a "key", uniquely defining a particular record. When information was being collected about a user, information stored in the optional tables would be found by searching for this key. For instance, if the login name of a user is unique, addresses and phone numbers for that user would be recorded with the login name as its key. This simple "re-linking" of related data back into a single collection is something that traditional computer languages are not designed for.

Now answer this question: How is information accessed in a relational model?

Output: a "key"

Input: Article: Beyoncé's lighter skin color and costuming has drawn criticism from some in the African-American community. Emmett Price, a professor of music at Northeastern University, wrote in 2007, that he thinks race plays a role in many of these criticisms, saying white celebrities who dress similarly do not attract as many comments. In 2008, L'Oréal was accused of whitening her skin in their Feria hair color advertisements, responding that "it is categorically untrue", and in 2013, Beyoncé herself criticized H&M for their proposed "retouching" of promotional images of her, and according to Vogue requested that only "natural pictures be used".

Now answer this question: Which company was accused of coloring Beyonce's hair?

Output:
L'Oréal
