I want to know the answer to the following question:
Which two Americans travelled to Europe during the Enlightenment and actively contributed to the scienific and political debate?
All the background I'm provided with is that "The Americans Benjamin Franklin and Thomas Jefferson came to Europe during the period and contributed actively to the scientific and political debate, and the ideals of the Enlightenment were incorporated into the United States Declaration of Independence and the Constitution of the United States.". Is that enough to answer the question?
