Nine-Year-Old Filipe and His Uncle Are Quite Knowledgeable About How

Nine-year-old Filipe and his uncle are quite knowledgeable about how to build a vehicle with a particular type of building toy. Filipe's mother asks Filipe and his uncle each to help one of Filipe's 6-year- old twin brothers make a vehicle from the building toy. How high-quality will Filipe's and his uncle's scaffolding be?

A) Filipe's scaffolding will be higher quality than his uncle's, because Filipe will be better able to relate to his brother.
B) Felipe's uncle's scaffolding will be higher quality than Filipe's because his uncle is older.
C) Filipe's and his uncle's scaffolding will be of the same quality since they both have the same level of knowledge about the task.
D) One cannot predict whose scaffolding will be of higher quality because quality of scaffolding has little to do with age or knowledge.
