Critical Reasoning

An anthropologist studying the social function of human skin has stated that tattoos are an ancient form of body art. Tattoos, she argues, function as a mode of self-identification: the placement and design of tattooed images communicate ideas of central importance to those who bear them. She hypothesizes that tattooing has surged in popularity in Western cultures over the last 10-15 years because of a desire to express individuality despite an increase in the mass production of other forms of personal decoration, such as clothing and jewelry.

Which of the following would be most useful to determine in evaluating the researcher's hypothesis?

(A) Whether the most popular tattoo designs are mass-produced
(B) Whether there has been in increase in the past 10-15 years in the number of people who wish to express individuality in their physical appearance, but feel that they cannot do so by other means
(C) Whether the ancient civilizations that developed tattoos used them to express individuality
(D) Whether people in Western cultures identify a desire to express individuality
(E) Whether attitudes toward mass-produced clothing and jewelry have changed in Western cultures over the last 10-15 years
