Final answer:
As exposure to the material increases over time, understanding of a subject generally 3) increases.
Step-by-step explanation:
When students are exposed to material over time, their understanding of the subject typically increases. The more they engage with the material, the more familiar they become with its concepts, principles, and applications. This increased exposure allows students to deepen their understanding, make connections between different topics, and apply their knowledge to solve more complex problems. For example, in mathematics, as students practice solving various types of equations and work on challenging problems, their understanding of mathematical concepts and problem-solving strategies improves over time.
