You conduct an experiment in which you expose a rat repeatedly to a 440 Hz tone and an electric shock. After a few trials, the rat begins to show signs of fear in response to the tone. In this paradigm, the electric shock is the , while the tone is the .

Explanation:

Classical Conditioning

This is a form of stimulus that does not bring about a new behavior but rather it makes an existing behaviour to resurface or occur.

Unconditioned Stimulus

This is often referred to as a natural stimulus that is brought about due to a response without prior learning such as food in the dog's mouth.

Unconditioned Response

They are simply unlearned, reflexive response such as dog's salivation

Conditioned Stimulus

In this type of stimulus, it is said to be originally neutral but comes to ignite or elicit a reflexive response such as the sound of bell. The Conditioned Response in this case is is commonly defined as a Learned reflexive response to a said or previous neutral stimulus. E.g Dog's salivation to sound of bell.
