What is the main purpose of the text discussing the behavior of the experimental group in Hanel's study?

• A. To describe a historical context
• B. To compare different experimental designs
• C. To explain a study's conclusion and how a research team arrived at that conclusion
• D. To present unrelated data

Answer: (C)

The main aim is to show how the study’s conclusion was reached, using the behavior of the experimental group as the central evidence and then explaining the reasoning that connects those observations to the conclusion. The text walks through what was observed, how those observations support the researchers’ interpretation, and the data and analyses that link results to the final takeaway. This helps you see why the conclusion follows from the evidence and how the researchers arrived at it, rather than merely describing events. It’s not about historical background, it doesn’t compare different experimental designs, and it doesn’t present unrelated data.
