I want to know the answer to the following question:
Along with coal and grain, what was the most important import in 18th century Plymouth?
All the background I'm provided with is that "Foulston was important for both Devonport and Plymouth and was responsible for several grand public buildings, many now destroyed, including the Athenaeum, the Theatre Royal and Royal Hotel, and much of Union Street.". Is that enough to answer the question?
Answer: no
