The correct answer to this open question is the following.
Although the question seems to be incomplete and no reference is attached, we can say that at Yankee Stadium, 200 people who had purchased food were asked to rate the quality of the food. The responses included a series of adjectives to qualify the food and the service of the concessions in the stand. People had to answer the questionary selecting adjectives such as 1. Poor. 2. Fair. 3. Good. 4. Very Good. 5. Excellent. This serves the concessions to know the opinion of the public and interpret the results in order to make decisions and offer a better service.
