Question

What Han invention was originally made using wood pulp?

Answer 1

I would say paper.If it is not paper then it is silk.

Answer 2

Well, think about it. You can just use process of elimination. Horse stirrups were made from brass and iron, and porcelain is ceramic. Silk came from silkworms so the only answer that makes sense is paper. Since this is the only logical response to your inquiry, the answer would be paper.
