The correct option is: They are formulated after several repeated investigations produce the same or similar conclusions.
The correct option is: Theories are formulated after several repeated investigations produce the same or similar conclusions.
To determine this, we need to understand the process of theory formulation. A theory is a well-substantiated explanation of some aspect of the natural world that is based on a body of evidence. Theories are not formulated based solely on a single experiment or investigation. Instead, they are developed over time through many repeated investigations that produce consistent and reliable results.
Scientists conduct experiments or investigations to gather data and analyze the results. As they collect more data and conduct further investigations, patterns and trends may begin to emerge. These repeated investigations help scientists to build a body of evidence that supports or refutes certain explanations. Once multiple investigations have produced similar conclusions, scientists can then formulate a theory to explain the observed phenomena.
Therefore, the correct option is: Theories are formulated after several repeated investigations produce the same or similar conclusions.
