How do you prioritize multiple assignments from different people?

I took a test on the computer where there were a series of legal terms I needed to know. There was also scenario-based questions about prioritizing work and in what order I would do this, with no other details. Question was something like what would you do first? Deal with the Subpoena just delivered, work on brief, file Summons and Complaint.

Deadlines are the general rule. Exception is, if high dollar amount, do first.
