Michael Moore’s film Sicko explores the U. S. health-care system and compares it to other nations’ health-care systems through the eyes of everyday people. One segment tells the story of a little girl in the United States who needed an expensive surgery to restore her hearing. The insurance company agreed to perform the surgery on one ear, but not both. They reasoned that the child would be able to hear out of one ear and did not really need to have hearing in both. The child’s parents sent a letter to the insurance company explaining that they were being interviewed by Moore for the film, adding, "Has your CEO ever been in a film before?" Shortly after this, the insurance company notified the family that the child’s surgery had been approved. Which theory best explains this family’s experience?

a. socialized medicine theory
b. structural functionalism
c. conflict
d. symbolic interactionism
