Which of the following is not a way that the crusades affected european culture?

I think you forgot to add the optionsbut...this is what it DID to:
Th Crusades brought back loot, they brought back Muslim knowledge about medicine, science, and philosophy. They brought back the Arabic numerals that we still use today. The Crusades started and ended as a military effort to conquer distant lands, but they became a great cultural exchange program as well in the process.
