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, please exapain this

Quite possible your experiment is in error. I not sure how u can do your experiment without this coming to play.Take a string about 2 ft. long and tie the ends together. With gloves on so the string want cut your hand , separate your hands quickly , causing the string to break. I found that almost always the slipping of the string will cut the string at the knot.
Good luck

Even in sharp pull & steady pull thread breaks on top of the stone.
Longer the thread strength losess. sharter the thread strength increas. hence the pressure applied on sharp pull & steady pull will breaks the longer thread above the stone.

Pulling sharply brings the inertia of the stone into play while pulling gently lets the weight of the stone be a factor.
