Ayaka and Ben were volunteers at a music festival. Ayaka noticed that Ben did not completed his share of the work on time. There
fore, Ayaka said to Ben, "I was wondering if you would like to have someone help you finish your task." Which kind of face was Ayaka trying to save for Ben
Positive face is defined as the concept in which a person tends to have a desire of appreciated in terms of personality and deeds by other people.The want that people should like and approve their work and acts.
According to the situation described in the question, Ayaka is trying to display positive face towards Ben so that he can complete his share of works with someone's or her help.In this way, she will get appreciated and liked by Ben for providing support to him .
I think it's trying to show the fact that you can't control something that is natural and the more you try to control it the more it comes for you if that makes sense like the states are trying to reopen but the virus in this case is coming for them
