text_A: In the 20th century, many individuals with Down syndrome were institutionalized, few of the associated medical problems were treated, and most people died in infancy or early adulthood. With the rise of the eugenics movement, 33 of the then 48 U.S. states and several countries began programs of forced sterilization of individuals with Down syndrome and comparable degrees of disability. While registration of family members with Down Syndrome was involuntary in Nazi Germany, Action T4 made public a program of voluntary euthanization.
text_B: From the way that Action T4 was described in the passage, could you legitimately say that a majority of American states had acted in a worse manner than Nazi Germany, on this specific issue?
YES.
