Which of the following is true about scientific theories?
I. New research is often done to learn more about existing scientific theories.
II. Scientific theories can be revised, changed, or even rejected.
III. Scientific theories are considered to be facts and cannot ever be modified.
IV. New scientific theories can be formed to explain new phenomena.
Answer (3)
Well surely 1, 2 and 4 are true, e.g, it was once thought that earth was the centre of the universe, this was revised and rejected. Scientists are still researching the existence of the universe using more advanced technology to test old theories. There are also new phenomena in which cannot be explained but there are theories to suggest why. But 3 is completely wrong as they are not treated as facts but a prediction until proven.
Scientific theories are regularly explored through new research, can be revised or even replaced, and new theories can be developed to explain new phenomena. However, while theories are evidence-based, they are not unchangeable facts. ;
Statements I, II, and IV are true while statement III is false regarding scientific theories. Scientific theories are dynamic and can change over time as new research and discoveries occur. They provide a framework for understanding a wide range of phenomena but are always subject to further testing and revision.
