Which of the following commands should be added to /etc/bash_profile to change the language of messages from an internationalised program to Portuguese (pt)? (Select TWO).

The `LANGUAGE` environment variable is a GNU extension for specifying a search path for message catalogs, but `LANG` and `LC_MESSAGES` are the primary POSIX variables for setting the locale and message language.

`MESSAGE` is not a standard environment variable used for locale or language configuration in Linux.

The `LANG` environment variable sets the primary locale for the system, which includes the language. Exporting `LANG="pt"` sets Portuguese as the default language for all locale categories.

The `LC_MESSAGES` environment variable specifically controls the language used for program messages, error outputs, and menus, allowing for fine-grained control over message localization by overriding the general `LANG` setting for this category.

`ALL_MESSAGES` is not a standard environment variable used for locale or language configuration in Linux.
