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).

`LANGUAGE` is a GNU extension that specifies a priority list of languages for message translation, but `LANG` and `LC_MESSAGES` are the more fundamental POSIX variables for setting the current locale and message language directly.

`MESSAGE` is not a standard environment variable used for controlling language settings in internationalized programs.

The `LANG` environment variable sets the overall locale, which includes the default language for all `LC_*` categories if they are not explicitly set, instructing internationalized programs to use Portuguese for messages.

The `LC_MESSAGES` environment variable specifically controls the language used for program messages, such as prompts, error messages, and status output, ensuring these are displayed in Portuguese.

`ALL_MESSAGES` is not a standard environment variable used for controlling language settings in internationalized programs.
