Answer:
Ralph is more stressed by the situation because Cory has a better set of social skills than Ralph.
Step-by-step explanation:
Social skills are attributes that make interactions with others easy and comfortable for people. The scenario shows that Cory is more lively and sociable, thus, his social skills are better than Ralph's. Ralph on the other hand is apprehensive because he is not very sociable and finds it difficult to manage his interactions with people.
Ralph's situation is worsened by the fact that he is unfamiliar with the people in the party.
