When forking an dual-licensed permissive/GPL project, can I drop one of the licenses?

문제

Consider an existing project that is dual-licensed GPL + either MIT or BSD.

Since it's dual-licensed, when I fork, can I pick one license in the fork? Or do my forked files need to continue to be dual-licensed?

It sure would be simpler to track only one license.
