I want to know the answer to the following question:
When did Lieutenant-Governor of New South Wales Francis Grose start suggesting Norfolk Island be closed as a penal settlement?
All the background I'm provided with is that "As early as 1794, Lieutenant-Governor of New South Wales Francis Grose suggested its closure as a penal settlement, as it was too remote and difficult for shipping and too costly to maintain.". Is that enough to answer the question?
Answer: yes
