The passage given below is followed by four alternate summaries. Choose the option that best captures the essence of the passage.
For nearly a century most psychologists have embraced one view of intelligence. Individuals are born with more or less intelligence potential (I.Q.); this potential is heavily influenced by heredity and difficult to alter; experts in measurement can determine a person's intelligence early in life, currently from paper-and-pencil measures, perhaps eventually from examining the brain in action or even scrutinizing his/her genome. Recently, criticism of this conventional wisdom has mounted. Biologists ask if speaking of a single entity called "intelligence" is coherent and question the validity of measures used to estimate heritability of a trait in humans, who, unlike plants or animals, are not conceived and bred under controlled conditions.
- A.
Biologists have questioned the long-standing view that 'intelligence' is a single entity and the attempts to estimate its heritability.
- B.
Biologists have questioned the view that 'intelligence' is a single entity and the ways in which what is inherited.
- C.
Biologists have criticised that conventional wisdom that individuals are born with more or less intelligence potential.
- D.
Biologists have started questioning psychologists' view of 'intelligence' as a measurable immutable characteristic of an individual.
A
Explanation
The paragraph contrasts the traditional psychological view of IQ as a single heritable trait with recent biological criticism. The core criticism is whether 'intelligence' is a single entity and whether heritability measures are valid in humans. Option A captures both key aspects accurately.
