Answer:
Putting together a model train set is an example of working with Things
Step-by-step explanation:
A model train set comes with a kit of many things that you must assemble. The items inside the kid are classified as "things" and therefore when you assemble the train, you are working with things.
You are not necessarily working with people when modeling this train set. There is a chance you could be, but that is unspecified and therefore un applicable.
You will be reading information, not working with it. The information is known as the instructions. You are reading and using the instructions, but that does not mean you are working with information.
You are not working with energy. Energy is not relevant when assembling this train kit. Energy has everything to do with science and physics, not assembling this train kit.
