Context and question: A significant and far-reaching shift in human subsistence and lifestyle was to be brought about in areas where crop farming and cultivation were first developed: the previous reliance on an essentially nomadic hunter-gatherer subsistence technique or pastoral transhumance was at first supplemented, and then increasingly replaced by, a reliance upon the foods produced from cultivated lands. These developments are also believed to have greatly encouraged the growth of settlements, since it may be supposed that the increased need to spend more time and labor in tending crop fields required more localized dwellings. This trend would continue into the Bronze Age, eventually giving rise to permanently settled farming towns, and later cities and states whose larger populations could be sustained by the increased productivity from cultivated lands.
What trend led to a major shift in the livelihoods of early cultures?
Answer: crop farming and cultivation
Context and question: Non-Australian citizens who are Australian permanent residents should be aware that during their stay on Norfolk Island they are "outside of Australia" for the purposes of the Migration Act. This means that not only will they need a still-valid migrant visa or Resident return visa to return from Norfolk Island to the mainland, but also the time spent in Norfolk Island will not be counted for satisfying the residence requirement for obtaining a Resident return visa in the future. On the other hand, as far as Australian nationality law is concerned, Norfolk Island is a part of Australia, and any time spent by an Australian permanent resident on Norfolk Island will count as time spent in Australia for the purpose of applying for Australian citizenship.
What does a Non-American citizen who is a resident need to return from Norfolk Island to the mainland?
Answer: unanswerable
