Final answer:
Common terms used today are 'Indians' and 'New England,' while 'Western Hemisphereans' is not common and 'Norumbega' is historical. The author includes various terms to address historical usage and the changing landscape of cultural sensitivity.
Step-by-step explanation:
Of the terms listed in the question, 'Indians' and 'New England' are commonly used today. The term 'Indians' has been widely used historically to describe the indigenous peoples of the Americas, although it is based on a misconception by early European explorers like Christopher Columbus who thought they had reached India. The term 'New England' refers to a region in the northeastern United States and continues to be widely recognized. 'Western Hemisphereans' is not a commonly used term, and 'Norumbega' refers to a legendary region of the Northeast coast of North America that is no longer in common use.
The author might include both familiar and unfamiliar terms to enlighten the audience about historical nomenclature and provoke thought on the evolution of language and cultural sensitivity. Using terms such as 'Indians' may reflect historical usage or the preferences of certain indigenous communities, while acknowledging that other terms may be preferred or more accurate in different contexts.
