READING I. Read the following text and answer the questions by choosing the option A, B, C or D. The Japanese have term , kenzoku, which translated literally means “family”. The connotation suggests a bond between people who’ve made a similar commitment and who possibly therefore share a similar destiny. It implies the presence of the deepest connection of friendship, of lives lived as comrades from the distant past. Many of us have people in our lives with whom we feel the bond described by the word kenzoku. They may be family members, a mother, a brother, a daughter, a cousin. Or a friend from grammar school with whom we haven’t take in decades. Time and distance do nothing to diminish the bond we have with these kinds of friends The question then arises: why do we have the kind of chemistry encapsulated by the word kenzoku with only a few people know and not score of others?
