Which of the following is NOT among Alaska's four largest industries?

• A. Oil and Gas
• B. Fishing and Seafood
• C. Software Development
• D. Tourism

Answer: (C)

The main idea here is understanding Alaska’s economic landscape and which industries have the biggest scale. Alaska’s largest industries by output and employment have traditionally been oil and gas, fishing and seafood, tourism, and government (federal/state). Oil and gas drive a lot of revenue and jobs, fishing and seafood are central to coastal communities and exports, tourism brings a wide range of seasonal and permanent jobs, and government payrolls support many residents as well. Software development exists and is important for diversification, but it does not reach the same scale as those four sectors. So software development is not among the top four industries in Alaska.
