The first and the last sentences are placed correctly, arrange the remaining sentences to form the alogical sequence and then choose the correct option.
I. Pavlov and his studies of classical conditioning have become famous since his early work between 1890-1930.

  1. The unconditioned stimulus (or UCS) is the object or event that originally produces the reflexive/natural response
  2. To summarize, classical conditioning (later developed by John Watson) involves learning to associate an unconditioned stimulus that already brings about a particular response (i.e. a reflex) with a new (conditioned) stimulus, so that the new stimulus brings about the same response.
  3. Pavlov developed some rather unfriendly technical terms to describe this process.
  4. Classical conditioning is "classical" in that it is the first systematic study of basic laws of learning/conditioning.

II The response to this is called the unconditioned response (or UCR). The neutral stimulus (NS) is a new stimulus that does not produce a response.

The question refers to Pavlov’s famous “classical conditioning “and how his works became famous during a certain period of time (1890-1930).
Line D will be a logical continuation of line 1 as it describes the term as “classical”{ it is the first systematic study of basic laws of learning/conditioning)
Line B summarizes “classical conditioning".
Line A will come before the last line as it describes the unconditional response.
So, the correct sequence will be DBCA.
