Question

1. what is the independent variable?

Explanation:

To determine the independent variable, we first need the context of the study or experiment (e.g., what factors are being manipulated or measured). Since that context is missing here, we can only provide the definition:

An independent variable is the variable that is manipulated or controlled by the researcher in an experiment or study. It is the factor hypothesized to cause changes in another variable (the dependent variable). For example, in a study testing how different amounts of fertilizer (independent variable) affect plant growth (dependent variable), the amount of fertilizer is the independent variable because it is the factor being changed to observe its impact.

If you provide the context of the problem (e.g., the experiment/study details), I can help identify the specific independent variable.
