Analyzing the 'Insight Theory of Learning' under the 'Gestalt Theory of Learning' proposed by Max Wertheimer, Koffka, and Köhler, which of the following main characteristics highlights the fundamental and cognitive difference between the famous experiment conducted on the chimpanzee named Sultan and Thorndike's 'Trial and Error Theory'?

According to Gestalt Psychology, learning is not merely the result of mechanical or sequential efforts, but is based on the ability to view a problematic situation as a whole and suddenly understand its internal relationships. Wolfgang Köhler proved through his experiments that when the chimpanzee (Sultan) obtained bananas by using sticks or boxes, he mentally restructured the entire situation in a single stroke rather than partially analyzing the problem, which is called 'insight'. In contrast, Thorndike's trial and error theory emphasizes reducing sequential errors.
