(A) Some people are born with greater possibilities or ‘potential intelligence’ than others.
(B) Intelligence is improved by learning.
(C) It is no longer thought that intelligence is a general quality, underlying all behaviour and inherited wholly from our parents.
(D) However, this potential may not develop unless it is encouraged and stimulated by influences surrounding the child from birth.
Choose the correct option :

After reading all the sentences, it can be inferred that the passage talks about how intelligence develops and is not an acquired quality.

Sentence C clears a misconception that intelligence is wholly inherited from our parents. Hence, it forms the introductory lines of the passage.

Sentence B clarifies the statement made in sentence C. Hence, it should be the second sentence of the passage.

Sentence A gives the idea that some people are born with greater possibilities than others. Sentece D follows this idea and gives the conclusion that though this is the case, the potential would develop only with the right influences.

Hence, the correct ordering of the sentences is CBAD
