Answer:
The answer is: B) The railroad felt that the demand for passenger service was inelastic and opponents of the rate increase felt it was elastic.
Explanation:
If the demand for a product or service is price inelastic, then if the price of that product or service increases, the quantity demanded will decrease at an smaller rate (e.g. price increases by 20%, quantity demanded decreases by 10%).
If the demand is price inelastic, the opposite happens. (e.g. if the price of a good increases by 10%, the quantity demanded for the product will decrease by 20%).
