The text adds the reader's synthesis of Stephenson's invention by showing that he implemented improvements that would double the speed of his first engine, as shown in option B.

We can arrive at this answer because:

  • The text shows how Stephenson produced an improved boiler from an old boiler he had already created.
  • This improved boiler was a success and allowed for faster and more efficient work.
  • One of the improvements was the increased engine speed compared to the engine speed of the old boiler.

The increase in speed was what motivated Stephenson to make new creations for the boiler. He wanted the new boiler to be faster and shorten the working time, allowing more products to be produced.
