Final answer:
Two changes that occurred when the British invaded New York City with the Lockton House were the arrival of the British fleet with over 100 ships and the occupation of Staten Island and Long Island by British troops.
Step-by-step explanation:
Two changes that occurred when the British invaded New York City with the Lockton House were:
1. The British fleet, commanded by Admiral Richard Howe, arrived with over 100 ships, causing concern and panic in the city. This display of British naval power heightened the threat of the invasion.
2. The British troops began arriving and landed on Staten Island, where they faced little opposition. They then moved to Long Island, which was well fortified and guarded, except for the Jamaica Pass, which was abandoned with only a token guard. These maneuvers allowed the British to establish a strong presence in New York City.
