Electric power utility companies use various fuel sources (e.g., coal, natural gas, nuclear) to generate electricity for their customers
What happens to the demand for natural gas used to generate electricity as we move from a short-run planning horizon to a long-run planning horizon? Why? A) Demand becomes more inelastic over time because the other fuel sources become more scarce, so there are fewer options available for electric power utilities in the long run.
B) Demand becomes more inelastic over time because all of the power generation plants tend to choose the same technology, which makes the industry less responsive to prices in the long run.
C) Demand becomes more elastic over time because the electric plant's technology becomes obsolete, and the power company has less flexibility to adjust to changes.
D) Demand becomes more elastic over time because the power companies have more options available and can adopt new generating technologies or substitutes for natural gas over the long run.

Jill Borts believes that the price elasticity of demand for her economics textbook is relatively inelastic. She argues "I was told I had to purchase a book written by Hubbard and O'Brien that is required by my instructor
If I wanted to buy a mystery novel I would have many authors to choose from. Therefore, the demand for mystery novels is more elastic than the demand for my textbook." Is Jill correct? A) She is correct that the textbook has a more inelastic demand, but that is because most students pay for their textbooks with credit cards. Most people pay for novels and other books with debit cards. B) She is correct. C) She is confused. She should have concluded that the textbook has a more elastic demand than a novel. D) The demand for the textbook is more inelastic, but Jill's reasoning is incorrect. The reason the textbook has an inelastic demand is that it is more expensive than any novel.
