Four-year-old Sergei can tell his Poppa how to wash the clothes. Yesterday, Sergei told Poppa, "First, get the dirty clothes from the basket. Next, put them in the washing machine. Now, add some soapy stuff. Close the washer lid and press the button. When the buzzer rings, it's all done!" According to Piaget, Sergei has:
A. equilibrated his assimilation.
B. accommodated his laundry fixation.
