Q: Passage: In 1994, several cable systems in Canada started carrying WUHF via the Cancom communications satellite in out-of-market areas where Fox was not otherwise available. However, it had been carried on cable in Belleville, Ontario and other communities on the north shore of Lake Ontario since the 1980s. It was formerly carried by Eastlink (in SD only) and on Bell Aliant FibreOP TV (in both SD and HD) for viewers in Atlantic Canada until late 2012 (January 30, 2013 in Eastlink's case), when it was replaced with WFXT in Boston, a former Fox O&O (now owned by Cox Media Group). The station is also carried in the Thousand Islands region of the North Country in the town of Hammond (via Citizens Cable TV) as well as in the provinces of Manitoba and Newfoundland and Labrador. WUHF has been carried on satellite systems since 1996 and it is currently the only Rochester-based television station seen in Canada on the Shaw Direct satellite provider

Q: Passage: Gray was called up for an England under-18s training camp in November 2013. He made his debut at that level on 18 February 2014, playing the whole of a 4–0 win against their Belgian counterparts in a friendly match at St George's Park. Two weeks later, he was involved in England's goal as they lost 2–1 to Croatia in the first match of a double-header. He received his first call-up to the under-19s for a friendly against Germany in September 2014, and made his debut as a second-half substitute. An ankle injury forced Gray's withdrawal from the squad for the 2015 European Under-19 Championship first qualifying round, but he was able to play his part in the elite round. He started the first match, against Denmark, and was involved in England's second goal in a 3–2 win, when his near-post flick was deflected over the line by a Danish player. The Football Association (the FA) credit Gray with the goal, although UEFA record it as an own goal. A substitute in the second group match, a win against Azerbaijan, he returned to the starting eleven for the final group match against France, but a 2–1 defeat meant England failed to qualify for the finals.
