Question 2
After the devastating tsunami of December 2004, dozens of Scientologists mobilized to effected regions of south Asia to join in the relief effort.
Instead of traditional medical aid, however, these pseudo scientists provided pamphlets along with touch assist treatment in which they touch wounded areas with a fingertip. What might the victims have thought about the efforts of the Scientologists? A) The victims might perceive their efforts as admirable if the Scientologists were also assisting in the distribution of food and clothing.
B) The relief efforts of the scientologists may have been perceived as questionable if they consisted only of passing out pamphlets and practicing their touch assist healing.
C) If the victims' wounds healed within a few days, it's possible that the victims may have attributed the healing to the touch assist.
D) All of the above are likely thoughts by the victims of the devastating tsunami.
