Therefore, most infants hate living in homes with green wallpaper.” What is the original source of this stat? How might this affect its reliability?

• What missing information may be relevant to interpreting the statistic?
• Could any of the words surrounding the statistic have more complicated meanings than what’s in the dictionary? What could they also mean?
