For each blank in the following passage there are four words or phrases marked A, B, C and D. Fill in each blank with the word or phrase that best fits the context.

Music is nice, people seem to say, but not important. When students and parents are asked to rate subjects according to their importance, the music arts are   50   at the bottom of the list. Too often, music is viewed as mere entertainment, but certainly not an education which should be first taken into account. This view is   51  . In fact, music education is beneficial and important for all students.

Music tells us who we are. Because music is an expression of the beings who create it, it    52   their thinking and values, as well as the social   53   it came from. Rock music   54   a lifestyle just as surely as does a Schubert song. The jazz influence that George Gershwin and other musicians introduced into their music is obviously American because it came from American musical   55  . Music expresses our character and values. It gives us identity as a society.

Music provides a kind of feeling that cannot be   56   any other way.   57   can explain how the sun rises and sets. The arts explore the emotional meaning of the same phenomenon. We need every possible way to discover and   58   to our world for one simple but powerful reason: No one way can get it all.

The arts are forms of thought as powerful in what they communicate as mathematical and scientific symbols. They are ways we human being “talk” to each other. They are the   59   of civilization through which we express our fears, our curiosities, our hungers, our discoveries, our hopes. The arts are ways we give form to our ideas and imagination so that they can be   60    others. When we do not give children   61   to an important way of expressing themselves such as music, we   62   from them the meanings that music expresses.

Science and technology do not tell us what it means to be human. The   63   do. Music is an important way we express the meaning and value of peace and love.

So music education is far more   64   than people seem to realize.
