Which price discrimination condition was satisfied by requiring students to show their ID card for their initial ticket purchase?

Question

Quizplus · Accepted Answer

Requiring students to show their ID card for their initial ticket purchase allowed the concert promoter to easily distinguish among groups of buyers with different price elasticities of demand. Students, who are typically on a tighter budget, were offered a lower price in the hope that they would be more likely to attend the concert. Requiring ID cards for the initial purchase allowed the promoter to ensure that only students were receiving the lower price, while still offering the higher price to other buyers who may be more willing to pay. This is an example of price discrimination based on the buyer's characteristics.
