Pinker and Bloom suggest that language is an evolutionary adaptation.What does language allow us to do,in their theory

A)  avoid heuristic fallacies 
B)  acquire information about the world second-hand 
C)  engage in more efficient introspection 
D)  use trial-and-error learning more effectively

According to Pinker and Bloom, language allows us to acquire information about the world second-hand, through communication with others. This allows us to benefit from the knowledge and experiences of others, which is a key advantage of language as an evolutionary adaptation. While language may also help us avoid heuristic fallacies or engage in more efficient introspection, these are not the primary benefits discussed by Pinker and Bloom. The idea that language helps us use trial-and-error learning more effectively is not mentioned in the passage.
