Provide complete answers to the following two questions.

1- For what types of activities are internal service funds used to account? Provide several examples. Is a government required to account for the activities you cite in an internal service fund, or may it account for them instead in its general fund?

2- What is the rationale for accounting for nonexpendable endowment funds on a full, rather than a modified, accrual basis? Why is it important that depreciation be charged on long-term assets held as fiduciary fund investments?
