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 in\xef\xac\x82uenced by heredity and difcult 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.

Explanatory Answer
The last line of the paragraph states the main idea: 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. Option A rephrases this.
The second half of option B is incorrect. The paragraph says biologists question the validity of measures used to estimate heritability, not the ways in which intelligence is inherited. Options C is not as comprehensive as A. Option D is incorrect as it says intelligence is 'immutable' while the paragraph only says it is difficult to alter.
