I want to know the answer to the following question:
What body of water affects Detroit's climate?
All the background I'm provided with is that "Detroit and the rest of southeastern Michigan have a humid continental climate (Köppen Dfa) which is influenced by the Great Lakes; the city and close-in suburbs are part of USDA Hardiness zone 6b, with farther-out northern and western suburbs generally falling in zone 6a.". Is that enough to answer the question?
Answer: yes
