Which of the following observations of children is the most objective? A. Chris took a toy truck from Alex. Alex cried, became angry because Chris took the truck, and then stamped his feet on the floor. He snatched the truck back from Chris, and ran to the caregiver. B. Joan was playing with blocks, building a structure, when Missy joined her. Joan looked afraid because Missy was much larger than she. But she eventually overcame her fear and let Missy play with the blocks. C. When Ann finished drawing with crayons, she put them back in the box and returned the box to the shelf, whereas Sue, obviously less disciplined, left hers scattered on the table. D. Eddie went to the shelf and chose a teddy bear to play with. He took a plastic spoon and bowl and repeatedly moved the spoon from the bowl to the bear's mouth.
