<image> There is a brown object that is the same shape as the large yellow object; what material is it?
gpt
The brown object shares its spherical shape with the larger yellow object, suggesting they could be made of similar materials. Without additional information, it's challenging to determine the exact material from a visual inspection, but common possibilities for such objects include rubber, plastic, or even wood, given the matte finish and shadow indicative of a solid, non-metallic material.
