Which two statements are accurate descriptions of how process data objects or project data objects...

Basic and complex data types can both be defined as either process or project data objects. 

Although project data objects allow you to define data objects that are used by all processes in a project, they are not global data objects. Each process within your project uses its own version of the data object. Project data objects are not used to share data between processes. To share data between processes, you must create data associations.
