Amusement parks often offer discounts to locals with IDs. This is an example of a. A direct discrimination scheme b. An indirect discrimination scheme c. Diminishing marginal returns d. Vertical integration

The correct answer is A. An direct discrimination scheme

Explanation:

Direct discrimination exists if certain individuals or groups are treated differently from most people, this includes favorable treatment such as benefits as well as unfavorable or negative treatments. Moreover, direct discrimination schemes differ from indirect discrimination schemes because these are supported by law, rules, etc. that directly define the difference in treatment and the groups or people affected by these.

The case presented is an example of an indirect discrimination scheme because the discounts to locals show a difference in treatment. Also, this difference is explicit because it is stated it only applies to locals, and this discrimination is supported by the policies or rules of the amusement park.
