Query: A family of freely slice good boundary links   We show that every good boundary link with a pair of derivative links on a
Seifert surface satisfying a homotopically trivial plus assumption is freely
slice. This subsumes all previously known methods for freely slicing good
boundary links with two or more components, and provides new freely slice
links.
