What process involves delving into a subject in detail to uncover underlying assumptions?

The process of examining a subject in detail is crucial for uncovering underlying assumptions. When we examine a topic, we dissect its components, analyzing each aspect critically to reveal insights that may not be immediately apparent. This involves questioning the validity of the information, evaluating evidence, and exploring the implications that arise from these assumptions.

In contrast, experimenting typically involves a trial-and-error approach to test hypotheses, and documenting refers to recording information without necessarily engaging in a critical analysis. Expressing, while important for communication, does not inherently involve the deeper level of scrutiny that examination entails. Therefore, the act of examining is clearly the most suitable process for revealing and understanding the foundational beliefs that influence a subject.
