premise: The blond-haired and blue eyed child holds the wooden airplane in his hands.

explanation_2: We have no idea if it was made by his grandfather, it could be made by anyone.
explanation_3: Just because a child is playing with a toy airplane does not infer that it was made by his grandfather.
