Answer:
a. The residential property owner and developer have moved to the nuisance and remedies vary.
Step-by-step explanation:
Ergonomics was in the area(1967) before the residential properties or projects(1999) came about. Therefore the residential occupants could be said to have moved into the nuisance, knowing full(not being aware not an excuse however) well that Ergonomics was operation in the same area. They would based on this get a different remedial result from a law suit that would only based on consideration for safety of residential occupants of the area.
