What is described as collections of facts and ideas that lead to change in mental development?

The correct answer, knowledge, refers to the accumulation of facts and ideas that contribute to a person's cognitive growth and mental development. Knowledge encompasses the information that has been processed, understood, and integrated into a person's understanding of a certain topic or concept. This process of accumulating knowledge is crucial because it not only involves memorization but also entails comprehension and the ability to apply the information in various contexts.

In educational settings, knowledge is often seen as the foundation upon which further learning takes place. It prepares individuals to make informed decisions, solve problems, and engage in critical thinking, which are all essential for driving changes in mental development. The other options relate to aspects of learning and mental processes but do not capture the full scope of how collections of facts and ideas specifically contribute to mental development in the same way that knowledge does.
