b. the majority of the 11-year-olds will state that the amount of water in the taller beaker is the same as in the original beaker.
c. the majority of the 9- and 11-year-olds will state that the amount of water in the taller beaker is greater in quantity.
d. the majority of the 7-year-olds will state that the amount of water in the taller beaker is the same as in the original beaker.
