  b. Mary's baby has a 50-50 chance of having Klinefelter syndrome.
  c. Mary is expecting a girl.
  d. Mary is expecting a boy.

Question 2

Several teachers tell you that they are teaching to students' right brains by spending a lot of time on painting, map interpretation, geometry, and other highly visual and spatial activities. Critique their claim using what you have learned about how the human brain functions.

Answer to Question 1

D

Answer to Question 2

Although the two hemispheres tend have different strengths (e.g., the left hemisphere specializes in language and analytic thinking, the right hemisphere in visual-spatial tasks and other tasks requiring synthesis), they constantly collaborate in day-to-day tasks. Even very simple tasks recruit numerous areas of the brain. It is virtually impossible to teach exclusively to one hemisphere or the other.
