I believe the answer is: Naturalistic theory
Naturalistic theory refers to the theory which see that everything that happen in universe could always be explained by logical approach. In research, having this theory would make researchers reluctant to make conclusion without objective evidence.
Answer: Unconditioned Stimulus
B) Conditioned Stimulus
Explanation:
In Classical conditioning, learning occurs when a neutral stimulus is paired with an unconditioned stimulus, the neutral stimulus becomes a conditioned stimulus which can bring about conditioned responses.
For example, unconditioned stimulus (food) is presented repeatedly just after the presentation of the neutral stimulus (bell). After conditioning, the neutral stimulus alone produces a conditioned response (salivation), thereby becoming a conditioned stimulus. From this example, if a dog salivates whenever it sees food but a bell is rung before the food is presented, Overtime just ringing the bell will make the dog to salivate.
The Gettysburg Address was given by Abraham Lincoln, no doubt. It was given at the Gettysburg National Cemetery, which is around 90 miles from the White House, so my best guess would be on a battlefield.
