Tod, here are my 2 cents:
For example 1, I don’t see this as an Agile vs. Predictive issue but more about sequence. “Inform the team” would be premature because you haven’t analyzed the impact yet. Regardless of your approach (agile or predictive), the next logical step is to assess the scope change first, then communicate based on that analysis. If the option had said “review the change with the team,” that would be different, but simply informing them skips proper evaluation. You need to be mindful of the wording in the questions.
Regarding example 2, I understand why retrospective was chosen, but since the question says “after completing a project,” lessons learned feels more aligned. Retrospectives are typically Agile iteration ceremonies, while lessons learned meetings apply to all project types at closure. While retrospectives include lessons learned and improvements, in my opinion, the broader and more approach-neutral answer here would be lessons learned. That said, it's also a tricky question.
