Final answer:
Isabella Lockton's location during the British invasion of New York is not mentioned in the novel. Women during the Revolutionary War did not hold government offices, but they did perform tasks like maintaining homesteads, among other roles.
Step-by-step explanation:
The character Isabella Lockton from the novel Chains, set during the Revolutionary War, is actually not mentioned as being in a specific location when New York was invaded by the British. The choices given (at home, visiting a friend, working in the market) do not apply since the novel does not specify her whereabouts during the invasion. Instead, the book focuses on the perspective of Isabel, a different character, during these events.
Regarding the question about the roles of women during the American Revolution, holding government offices is not one of the tasks women performed during this time. Women were known to take on many crucial roles such as maintaining their homesteads, serving as messengers, nurses, and even spies, but they did not hold government office positions during the Revolution as that was not permitted for them in that era.
