B. Bisma’s performance intelligence score but not necessary her verbal intelligence score will be below average in both childhood and adult hood.
C. Bisma’s intelligence score will be below average in both childhood and adulthood.
D. Casual observation of Bisma’s behavior cannot be use to predict her later intelligence score.
