What Did Whitmire's Study Uncover About Gender and Education

What did Whitmire's study uncover about gender and education?

A) Boys have short attention spans and do not like to listen to authority, so they tend to have a harder time conforming to school rules and norms.
B) Boys and girls have different learning styles and the school environment is more conducive or positive for girls than boys.
C) Teachers require less of male students than female students and focus instead on their social development and physical activities.
D) Boys tend to score dramatically lower on standardized tests than girls, which may have to do with testing bias or a lack of motivation for boys to do well.
