I need help for the following assignment.

In the microeconomics book section 7.2,it states: "The pattern of costs varies among industries and even among firms in the same industry. Some businesses have high fixed costs, but low marginal costs." Aside from the examples cited in the book, identify one industry with high fixed costs in the short run. Then, identify an industry with high marginal costs in the short run. Be sure to analyze specific examples of costs to justify your choices.
