Explanation:

First Question (about classical conditioning pioneer)

To determine who is famous for classical conditioning: B.F. Skinner is known for operant conditioning, Edward Thorndike for trial - and - error learning, Sigmund Freud for psychoanalysis. Ivan Pavlov is renowned for his work on classical conditioning (like the dog - bell experiment).

• Option 1: A neutral stimulus is not about an animal's response.
• Option 2: A response that happens automatically is an unconditioned response, not related to a neutral stimulus.
• Option 3: Something that naturally brings a response is an unconditioned stimulus.
• Option 4: A neutral stimulus is a stimulus that, in the beginning, does not elicit a natural (unconditioned) response. So "Something that wouldn't normally cause a natural response" matches the definition of a neutral stimulus.

Answer:

Ivan Pavlov
