Q: Passage: CBC Television stations can be received in many United States communities along the Canadian border over-the-air and have a significant audience in those areas. Such a phenomenon can also take place within Great Lakes communities such as Ashtabula, Ohio, which received programming from the CBC's London, Ontario, transmitter, based upon prevailing atmospheric conditions over Lake Erie. As of September 2010 CBC shut down its analogue transmitter and decided not to replace it with a digital transmitter. As a result, there is now a giant hole in the coverage of CBC in South-Western Ontario. Both CBC - Toronto and CBC - Windsor are both over 100 miles from London, ON and out of range for even the largest antennas[citation needed].

A: What location in the United States has the highest viewership of CBC programming?
****
Q: Passage: The innovative production techniques devised by post-punk producers such as Martin Hannett and Dennis Bovell during this period would become an important element of the emerging music, with studio experimentation taking a central role. A variety of groups that predated punk, such as Cabaret Voltaire and Throbbing Gristle, experimented with crude production techniques and electronic instruments in tandem with performance art methods and influence from transgressive literature, ultimately helping to pioneer industrial music. Throbbing Gristle's independent label Industrial Records would become a hub for this scene and provide it with its namesake.

A: Who avoided post-punk production?

Q: Passage: Internal party disunity compounded the difficulty of identifying lawmakers who might have informally functioned as a minority leader. For instance, "seven of the fourteen speakership elections from 1834 through 1859 had at least twenty different candidates in the field. Thirty-six competed in 1839, ninety-seven in 1849, ninety-one in 1859, and 138 in 1855." With so many candidates competing for the speakership, it is not at all clear that one of the defeated lawmakers then assumed the mantle of "minority leader." The Democratic minority from 1861 to 1875 was so completely disorganized that they did not "nominate a candidate for Speaker in two of these seven Congresses and nominated no man more than once in the other five. The defeated candidates were not automatically looked to for leadership."

A:
What atmosphere was most prevalent in congress from 1834 through 1859?
