Final answer:
The statement about bubble sort is false; larger elements bubble up to the top, and smaller ones sink to the bottom. On the other hand, when a magnet shatters, all pieces will have north and south poles.
Step-by-step explanation:
The statement that in a bubble sort, the smaller elements move toward the bottom, and the larger elements move toward the top of the list is false.
Bubble sort is a comparison-based algorithm in which adjacent elements are compared and swapped if they are in the wrong order. This process is repeated until the list is sorted. In bubble sort, it's actually the larger elements that tend to 'bubble up' to the top of the list (end of the array), while the smaller elements 'sink' toward the bottom (beginning of the array) with each iteration.
However, the statement provided in the question seems to be a mix-up of concepts. The true statement is: If a magnet shatters into many small pieces, all the pieces will have north and south poles. Each piece of a shattered magnet will indeed retain a north and a south pole, no matter how small it is.
