2. Brief Explanations

   To determine the correct word, we analyze the context. The steam engine was developed by enhancing or making better an original invention. "Improving" means making something better, which fits the context of developing the steam engine from a prior invention. "Scraping" (removing or rubbing off) and "mass producing" (producing in large quantities) do not fit the context of the steam engine's development from an original invention.
