In the Personal Application,Evaluating the Concept of "Two Minds in One," what was the conclusion regarding left-brain and right-brain thinking

A)  Right-brain people benefit most from learning to do more left-brain activities. 
B)  There is strong evidence to support modification of school curriculum to support both types of thinking. 
C)  Career choice is strongly correlated with which side of the brain is most dominant. 
D)  The link between hemispheric lateralization and ability is speculative and unsupported.

The conclusion of the Personal Application evaluating the concept of "Two Minds in One" was that the link between hemispheric lateralization (left-brain and right-brain thinking) and ability is speculative and unsupported. Therefore, option D is the correct answer. The article suggests that there is no scientific evidence to support the idea that people have a dominant side of the brain and that different kinds of thinking are linked to different sides of the brain. Instead, research suggests that both hemispheres of the brain are always working together to handle most mental tasks.
