I'm going to say False but I think the person gets a foul.
Answer:
The scientific method is the process in which, ideas in form of hypotheses, are tested against the real world through evidence which is obtained from observation of phenomena.
Explanation:
The scientific method is self correcting in the sense that, it involves coming up with an idea, then making an hypothesis, then making the observation which shall be tested against the idea. Further there is experimentation to confirm the validity of the hypothesis.
All of the above are testing mechanisms, that scientist use to provoke their idea with the real world facts, in the process, the idea might prove wrong and thereby shall have self corrected.
Scientific knowledge is cynical in the sense that, at each stage, we expect to prove the hypotheses wrong.
If dichloromethane is swapped out and ethyl acetate is used in its place, the extracts then obtained would be highly anti-radical and would be more efficient than dichloromethane.
Since "like dissolves like," ethyl acetate is a polar molecule that works well as a solvent to extract the polar caffeine molecules from coffee beans. The ethyl acetate molecules bind to the caffeine molecules, which then move through the bean cells' cell membranes. After all, the ethanol:water (1:1) solvent combination has been demonstrated to be the best for recovering catechins and delivering extracts with the highest antiradical activity.
Dichloromethane is a volatile colourless liquid used as an organic solvent in many industries. One of its main application is that it used to extract caffeine because of its highly effective solvent nature. Because DCM is a non-polar solvent and caffeine is readily soluble in DCM, it can easily be extracted without losing its aroma.

Tom refused to accept Sam's input and change his attitude. Interestingly, the input provided by Sam further strengthened Tom's initial attitude. This is an example of a: <u>contrast effect</u>.
<u>Explanation</u>:
A contrast effect is the term used in psychology to explain the aggravation or decline, cognition or related performance as a result of consecutive or simultaneous exposure to a stimulus of lesser or greater value in the same dimension.
The type of contrast depends upon the how the participant considers a situation. There are two types of contrast effect. They are
i) Positive contrast effect
ii) Negative contrast effect
In the above scenario, Tom and Sam were discussing about the tax rates. Conflict arises between them when Sam objects Tom’s view on tax rates. Tom got aggravated and strengthened his attitude.
