When did steam engines all of a sudden become internal combustion engines?

I thought the steam engine was the answer to a question of what was NOT an internal combustion engine but I may not have remembered it right.

Not impressed with the thing either.

I miss read the answer, it said Stenson also built America's first steam engine. Also, it seems like only about half the questions were actually about engines.

I did the engines quiz after and got all of them.
