Here's how to break down the question and find the answer:

What is a scientific theory?

* A scientific theory is a well-substantiated explanation of some aspect of the natural world that can incorporate facts, laws, inferences, and tested hypotheses.

* It's not just a guess or a hunch; it's backed by a large body of evidence.

What are the results of scientific theories?

* Predictions: Scientific theories allow us to predict future events or phenomena.

* Explanations: Theories provide a framework for understanding observations.

* Technological advancements: Theories often lead to the development of new technologies.

* Improved understanding: Theories help us deepen our knowledge of the natural world.

What is NOT a result of scientific theory?

The answer is personal opinions or beliefs. Scientific theories are based on evidence and rigorous testing, not on personal feelings or opinions.

Important Note: While a scientific theory can be challenged and updated with new evidence, it's incorrect to say that a theory is just a "guess." It represents the best explanation we have based on the current scientific understanding.
