Which example best describes the zone of proximal development?

The zone of proximal development, often abbreviated as ZPD, is the difference between what a learner can do without help, and what they can't do.

For instance, an instructor is instructing students regarding the water cycle. If an instructor has already instructed a lesson on the thought of evaporation, the teacher ought to use this previous information of evaporation once introducing info regarding condensation. The kid can then be ready to build connections between the various phases of the water cycle.
