Question 3

Minneapolis business Rogue Chocolatier sells specialty chocolate bars with a high cocoa content. Most chocolate companies use already processed chocolate to craft their sweets.

For the past 15 years the American public has wanted to buy big trucks. The Big Three automakers delivered, investing billions in plants that build gas guzzlers. Now, when customers walk into showrooms, gas mileage is on their mind. Retooling the industry will take years, so in the meantime GM, Ford and Chrysler are tweaking their existing models. They're changing tires, adjusting transmissions and exhaust valves in hopes of getting one or maybe two more miles per gallon. Which of the decisions by the Big Three to gain gas mileage is a short run decision?
A) adjusting exhaust valves
B) adjusting transmissions
C) changing tires
D) All of these decisions are short run decisions.
