 The Unmarked Clock: Chloe is looking at an unmarked clock with just a minute hand, which jumps discretely between its positions. The hand is pointing somewhere around where the 4 would be, if it were marked, which of course it isn’t. Chloe is wondering: is the hand pointing to the 19? The 20? The 21? (call those propositions “P19”, “P20”, and “P21”).
