Task: Question Generation
Input (English): The city is home to 15 am and FM radio stations, two of which are French-language stations. St. John's is the only Canadian city served by radio stations whose call letters do not all begin with the letter C. The ITU prefix VO was assigned to the Dominion of Newfoundland before the province joined Canadian Confederation in 1949, and three AM stations kept their existing call letters. However, other commercial radio stations in St. John's which went to air after 1949 use the same range of prefixes (CF–CK) currently in use elsewhere in Canada, with the exception of VOCM-FM, which was permitted to adopt the VOCM callsign because of its corporate association with the AM station that already bore that callsign. VO also remains in use in amateur radio.
Output (English): How many radio station does the city have?
