In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

[EX Q]: Besides sheriffs and posses, who helped keep the peace?, Context: In the American Old West, policing was often of very poor quality.[citation needed] The Army often provided some policing alongside poorly resourced sheriffs and temporarily organized posses.[citation needed] Public organizations were supplemented by private contractors, notably the Pinkerton National Detective Agency, which was hired by individuals, businessmen, local governments and the federal government. At its height, the Pinkerton Agency's numbers exceeded those of the United States Army.[citation needed]
[EX A]: Army

[EX Q]: What will allow cellphones to share in the media of the 3 Sky 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.
[EX A]: mobile applications

[EX Q]: What additional point is made about the main subject discussed in the passage?, Context: The other Ancient Greek dialects, Ionic, Doric, Aeolic, and Arcadocypriot, likely had the same three-way distinction at one point, but Doric seems to have had a fricative in place of /t/ in the Classical period, and the Ionic and Aeolic dialects sometimes lost aspiration (psilosis).
[EX A]:
the Ionic and Aeolic dialects sometimes lost aspiration (psilosis)
