Dr Stanley conducted an experiment regarding the effect that various colors have on
  mood.
 
  His original hypothesis stated that colors on the lower end of the electromagnetic
  spectrum (approximately 450nm-550nm) would produce the greatest levels of elation
  (good mood) whereas colors on the higher end of the spectrum (approximately 600nm-700nm) would produce the lowest levels of elation (bad mood). Dr Stanley put one
  group of participants in a room in which the only colors were those which exist on the
  spectrum between 450nm-550nm. Then he put another group of people in a room in
  which the only colors were those which exist on the spectrum between 600nm-700nm.
  He then personally interviewed each of the participants and rated their subsequent level
  of elation (mood). His findings, which support his hypothesis, indicate that participants
  who were in the room with colors between 450nm-550nm were subsequently found to
  have greater levels of elation (better mood) than those in the 600nm-700nm colored
  room. A potential problem with this experiment may be ________________, and one
  way that Dr Stanley could have prevented this may have been to use a ______________.
  A) Placebo effect :: Double blind design
  B) Experimenter bias ::Double blind design
  C) Placebo effect :: Placebo control group
  D) Experimenter bias:: Single blind design
