Answer 1

I disagree.

Children who have very limited educational backgrounds will usually not score as well as those with rich learning experiences. Would you expect a five-year-old whose mother has a limited vocabulary and has not traveled more than a few blocks from home to do the same on a verbal IQ test as one from a home with educated parents?
