Answer 1

Maybe you are thinking about the Memory System known as "The Journey System".  You remember things in order by visualizing a trip (journey) you are taking and see the answers as objects along the trip.  You then link each object to the previous one.  The more outrageous the visual (picture in your mind's eye), the more likely you are to recall them later.
