Final answer:
The provided text describes the experimentation phase of the scientific method, where scientists test their hypothesis by collecting and analyzing data from experiments to draw conclusions.
Step-by-step explanation:
Understanding the Mentioned Part of the Scientific Method
The text provided describes the process whereby scientists test the hypothesis through experimentation. Specifically, conducting an experiment involves collecting data, analyzing it (often with statistical or mathematical methods), and drawing conclusions based on the results. This step is crucial because it determines whether the hypothesis is supported or rejected. Subsequent actions depend on these results, including refining the hypothesis or developing a new one if necessary. The experimentation step in the scientific method also includes the repetition of experiments to confirm the findings, making the results more reliable.
In light of this, the part of the scientific method that the text explains is A. Experimentation.
