Answer: (E)

Verified step by step guidance

1. Understand the four-stage hypothesis: This hypothesis suggests a sequence of stages that could have led to the origin of life from non-living matter. The stages include the formation of small organic molecules, the assembly of these molecules into polymers, the formation of protocells, and the development of self-replicating molecules.
2. Recognize the scientific method: In science, hypotheses are valuable because they lead to testable predictions. A hypothesis is not necessarily proven true or false but is useful if it can be tested through experiments and observations.
3. Identify the role of testable predictions: The four-stage hypothesis is useful because it generates specific predictions about the conditions and processes that could have led to the origin of life. These predictions can be tested in laboratory experiments or through observations of natural phenomena.
4. Consider the nature of scientific theories: Scientific theories are not proven in an absolute sense but are supported by evidence. Theories are considered useful if they provide a framework for understanding observations and making predictions.
5. Evaluate the hypothesis in the context of scientific inquiry: The value of the four-stage hypothesis lies in its ability to guide research and experimentation. By leading to testable predictions, it helps scientists explore the possible pathways for the origin of life and refine their understanding based on empirical evidence.
