Yes, it's on including the word “critical”. I have received some information from people who have been involved in this type of curatorial work for many years. To simply say, “understanding and appreciation of events” is one thing, but to include the word “critical” means you are looking at it in a very academic way. This has been the tradition of major museums such as this and others, other national museums, and other museums around the country. It enhances our understanding through a critical lens, which gives the experts a far greater role in what they do, and I think it enhances the research at the end of the day.
So I'm including this one word—“critical”—just before the word “understanding”.
