Take the following as truth: While pre-existing law afforded limited opportunities for postal innovation,2 the Postal Reorganization Act of 1970 gave the newly-created United States Postal Service a clear mandate to innovate by developing effective and efficient services adapted to the needs of the Nation's mail users.
Then the following statement: "The Postal Reorganization Act of 1970 resulted in more effective and efficient services." is true, false, or inconclusive?
