The contents of packages can be shared by many applications. -2. you can achieve information hiding by making package constructs private-actually theses are some of the advantages of the package, sharing the package among applications and hide the logic of the procedures and function that are inside the package by declaring them in the package header and write the code of these procedures and functions inside the package body. incorrect answers: a: packages can not be nested b: parameters cant be passed to a package; parameters can be passed to procedures and functions only. c: by the first time you call a procedure, function, or reference a global variable within the package, the whole package will be loaded into the memory and stay there, so when ever you need to reference any of the packages constructs again you will find it in the memory
