TOEFL TPO -1 Writing Task 2 Sample: Scientific method consists of the process of observing things, raising some problems, proposing the underlying principles as hypotheses, planning and executing experiments to verify them, analyzing the results, and drawing conclusions. Concepts established by scientific methods are verifiable by others, and the experimental results are reproducible. However, there are/were so-called pseudoscience-level theories, well-known but not scientifically verified, and medical treatments whose effectiveness has/had not been scientifically confirmed. In addition, even some research results published as verified by scientific methods are/were not actually verified due to artificial data manipulation or some experimental errors.
Give an example of such theory, medical treatment, or research result that was not/has not been scientifically verified. Outline that example from a scientific point of view (not from an ethical point of view) and describe specifically how it has not been scientifically verified. • LingoLeap
