Answer to Question 1

C

Answer to Question 2

Eminem likely wants to allow his most enthusiastic fans the op-portunity to see him in concert. He also has the incentive to promote his album by the publicity he gets from having the free concert and the re-sulting massive demand for tickets. This publicity will lead to increased sales of his album and increased income to him.
Eminem's decision to give a free concert had elements of both self-interest and social interest. To the extent that his decision was motivated by the free publicity and rise in album sales, the decision was motivated by self-interest. However to the extent that a desire to allow his most enthusiastic fans the chance to see him perform, the decision also had elements of social interest.
