HOTSPOT You need to implement ribbon display rules to control availability for the scoring command button. Which rule types should you use? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point. 
EntityPrivilegeRule and FormStateRule. The key detail is they want to control the button by user permissions (so EntityPrivilegeRule) and whether the form is new or existing (FormStateRule), not a specific field's value. If they asked about a certain field value, then ValueRule would matter. I think that's what flips some people up here, agree?
Is this asking for rules to check both the user's rights and if the form is new or not? Just want to confirm if ValueRule applies or not here.
Is the display based on just user permissions and form mode, or does it depend on a field value too? If you only want to show the button for users with certain privileges and in certain form states, I'd think EntityPrivilegeRule and FormStateRule fit better.
