Historical story

Which event could not be placed in the second slot?

Event that cannot be placed second:

- "Drank coffee"

Reason:

The first event is "Brushing teeth". It makes most sense to place an event related to the morning/breakfast routine in the second slot. "Went for a walk" and "Read the newspaper" are common morning activities. "Drank coffee" can occur at any time during the day, so it doesn't fit as well in the second slot.
