I know, right? I mean, those are all important documents, but they'd hardly be recognizable. Would these contestants have been in the audience for the FJ with the Articles of Federation? That was on the 18th, but I don't know how many sit in the audience (if there is one at this time), and as I recall, they film a reduced number of shows a day. Not sure where I'm going with this except that perhaps it influenced them in some way.
The Ivies are familiar to me only as "the Ivies" - for the most part I couldn't tell you which universities were in them (though I would probably guess Yale), and I couldn't tell you where most of them are. I did think of Dartmouth, but I thought it was in Vermont. So there you go.
I had a memory related to where I lived as well, so I got it without a problem. I moved around a lot until my 30's, so I could tie events to where I lived. These days, it all blurs because I've lived in one place for so long.
