> Which statements are true about GitHub Marketplace?
Honestly, I have never heard about the term GitHub Marketplace at all. Frankly, I don't want to relies on random proprietary SaaS apps somebody selling on random software distribution platforms.
> What is a workflow?
I don't know. Isn't it possible to (indirectly)achieve every candidates by GitHub Actions? Also, the term is used vague even by GitHub itself. The GitHub documents refer to flow or actions or whatever.
> Which statements are true about organizational membership
I don't know. Is reciting this knowledge helps on any way meaningful?
