Books, and other things etc.
An effective argument is established by taking the time to look at both sides of an issue.
Discrediting someone's argument or learning the popular opinion is not a good way of creating arguments, while it is not very subjective to decide what is better and what is worse.
Answer:
Mr Dunbar is using the tool of Association.
Explanation:
In psychology, Association simply refers to the practice of linking two or more information for ease of recall. This is the way the human brain is wired to recall.
Every information in the mind is an organisation of associated ideas, occurrences, things and so on.
So to help students learn and remember faster, good teachers use the power of association to help them recall easily.
For example, do you remember the song "Do-Re-Mi" from Sound of Music?
That song teaches one how to memorize the music sofa in a fun and easy to recall way using imagery and association.
Cheers!
