[考題] 王靖文法閱讀的問題

[rabbitcola ()]

各位英文版上的高手，小妹不才，
上王靖老師文法閱讀時有一題老師沒講到(也非常可能是我漏聽)
回家上網搜尋此題答案，有點疑問
原文：
For many years, sociologists and historians have referred to the United
States as a cultural “melting pot,” in order to suggest the successful
integration into American society of the massive waves of immigration which
have marked American history. This term has been primarily a complimentary
one, implying that immigrants invariably embrace not only American ideals,
but a pervasive “American” culture. Also, the term suggests that American
immigrants successfully leave behind the turmoil of their home countries
which has caused them to come to the United States, thus “melting” into
American society.
However, in recent years, this term has lost much of its popularity,
primarily because of an increasing emphasis on diversity among ethnic groups.
Ironically, this emphasis springs from another American ideal, strong
individuality. Instead, many prefer to refer to the U.S. as a “salad bowl,”
 viewing each of the many ethnic groups in America as a component of a salad,
thus preserving its own identity in the salad, but, at the same time,
interacting with the other vegetables to create a delightful mix and variety.
Certainly the term makes a great deal of sense with regard to geography, as
ethnic distribution in the United States is hardly uniform. New York, with
its Chinatown and Little Italy, is an excellent example of this separation.
However, the term is primarily used with reference to the various cultures
and sensibilities of ethnic groups in the U.S.
