A stone hangs by a fine thread from the ceiling, and a section of the same thread dangles from the bottom of the stone. If a person gives
a sharp pull on the dangling thread, where is the thread likely to break : below the stone or above it? What if the person gives a slow and steady pull?

I would say in a slow pull, the upper thread would break first, because it always has the additional weight of the stone being applied to it, that the lower thread does not.
In a sharp pull, the stone acts as a dampener, and is the force to hold the upper thread in place, so the lower thread breaks.
That's my guess and reasons. (And I didn't go look anything up.)

it depends on the direction in which the string is pulled: horizontally or vertically
