Example Input: What feature allows the Sky system to distribute media among all 3 products?, Context: On 18 November 2015, Sky announced Sky Q, a range of products and services to be available in 2016. The Sky Q range consists of three set top boxes (Sky Q, Sky Q Silver and Sky Q Mini), a broadband router (Sky Q Hub) and mobile applications. The Sky Q set top boxes introduce a new user interface, Wi-Fi hotspot functionality, Power-line and Bluetooth connectivity and a new touch-sensitive remote control. The Sky Q Mini set top boxes connect to the Sky Q Silver set top boxes with a Wi-Fi or Power-line connection rather than receive their own satellite feeds. This allows all set top boxes in a household to share recordings and other media. The Sky Q Silver set top box is capable of receiving and displaying UHD broadcasts, which Sky will introduce later in 2016.
Example Output: a Wi-Fi or Power-line connection

Example Input: What did Kerry later run for?, Context: The junior U.S. Senator from Massachusetts, Paul Tsongas, announced in 1984 that he would be stepping down for health reasons. Kerry ran, and as in his 1982 race for Lieutenant Governor, he did not receive the endorsement of the party regulars at the state Democratic convention. Congressman James Shannon, a favorite of House Speaker Tip O'Neill, was the early favorite to win the nomination, and he "won broad establishment support and led in early polling." Again as in 1982, however, Kerry prevailed in a close primary.
Example Output: Senator

Example Input: How certain is it that Asian classroom goals are in line with western countries' goals?, Context: It's not clear, however that this stereotypical view reflects the reality of East Asian classrooms or that the educational goals in these countries are commensurable with those in Western countries. In Japan, for example, although average attainment on standardized tests may exceed those in Western countries, classroom discipline and behavior is highly problematic. Although, officially, schools have extremely rigid codes of behavior, in practice many teachers find the students unmanageable and do not enforce discipline at all.
Example Output:
