Question: CBC announced on April 4, 2012, that it will shut down all of its approximately 620 analogue television transmitters on July 31, 2012 with no plans to install digital transmitters in their place, thus reducing the total number of the corporation's television transmitters across the country down to 27. According to the CBC, this would reduce the corporation's yearly costs by $10 million. No plans have been announced to use subchannels to maintain over-the-air signals for both CBC and Radio-Canada in markets where the corporation has one digital transmitter. In fact, in its CRTC application to shut down all of its analogue television transmitters, the CBC communicated its opposition to use of subchannels, citing costs, amongst other reasons.
Is there an answer to this question: The CRTC has limited the CBC to operating how many digital transmitters?

Answer: unanswerable


Question: There are more than 200 thermochemical cycles which can be used for water splitting, around a dozen of these cycles such as the iron oxide cycle, cerium(IV) oxide–cerium(III) oxide cycle, zinc zinc-oxide cycle, sulfur-iodine cycle, copper-chlorine cycle and hybrid sulfur cycle are under research and in testing phase to produce hydrogen and oxygen from water and heat without using electricity. A number of laboratories (including in France, Germany, Greece, Japan, and the USA) are developing thermochemical methods to produce hydrogen from solar energy and water.
Is there an answer to this question: What are the thermochemical cycyles in a testing phase for?

Answer: produce hydrogen and oxygen from water and heat without using electricity
