What is the term used for a basic question or problem?

The term "stem" refers to the basic question or problem presented in an assessment or examination context. It serves as the foundation for what the respondent is required to address or solve. In a multiple-choice setting, the stem poses the question that guides the choice of answers, framing the context for the options available. Utilizing the term "stem" in educational and testing environments underscores its role in conveying the primary query or issue that needs resolution.

In contrast, a hypothesis is a proposed explanation that can be tested and explored, an argument represents a statement or series of statements intended to persuade, and a conclusion is the final statement or summary derived from an analysis or argument. These terms are related to different aspects of reasoning or inquiry, making "stem" uniquely appropriate for identifying the fundamental question or problem at hand.
