答案是B还是C 呀?

      Some historians contend that con-

       ditions in the United States during the

       Second World War gave rise to a

Line       dynamic wartime alliance between

  (5)      trade unions and the African American

community, an alliance that advanced

the cause of civil rights.  They con-

clude that the postwar demise of this

vital alliance constituted a lost oppor-

 (10)      tunity for the civil rights movement that

followed the war.  Other scholars,

however, have portrayed organized

labor as defending all along the rela-

tively privileged position of White

 (15)      workers relative to African American

workers.  Clearly, these two perspec-

tives are not easily reconcilable, but

the historical reality is not reducible

to one or the other.

 (20)            Unions faced a choice between

       either maintaining the prewar status

       quo or promoting a more inclusive

approach that sought for all members

the right to participate in the internal

 (25)      affairs of unions, access to skilled

and high-paying positions within the

occupational hierarchy, and protec-

tion against management’s arbitrary

authority in the workplace.  While

 (30)      union representatives often voiced

this inclusive ideal, in practice unions

far more often favored entrenched

       interests.  The accelerating develop-

ment of the civil rights movement

 (35)
                       following the Second World War

exacerbated the unions’ dilemma,

forcing trade unionists to confront

contradictions in their own practices.
