Final answer:
An aquiclude prevents water movement and an aquifer allows it; the correct answer is a) Prevents, Allows.
Step-by-step explanation:
An aquiclude prevents water movement while an aquifer allows water to move. Therefore, the correct answer to the student's question is: a) Prevents, Allows.
An aquiclude, due to its impermeable nature, acts as a confining layer that inhibits the flow of groundwater.
Conversely, an aquifer has the permeability necessary to facilitate the movement of water, thus allowing it to be a significant reservoir of fresh water that can be used as a source of drinking or irrigation water when tapped through wells.
