Question

Quizplus · Accepted Answer

Seriation refers to the ability to arrange items or objects in a specific order based on a particular characteristic (in this case, height). Yael's class is being asked to line up in order of height which demonstrates their ability to use seriation. Conservation refers to understanding that the quantity of something remains the same despite any changes in appearance, reversibility pertains to the ability to mentally reverse a set of actions, and classification involves grouping items based on shared characteristics. None of these concepts are particularly relevant to the task of lining up by height.
