Andrea grew up enjoying her Italian grandmother's homecooked meals. Chicken
and pasta with meatballs were her favorite foods. But after Andrea graduated
from college, found a job, and got married, she became a vegetarian and no
longer ate chicken or meatballs. Briefly explain which of the following
statements provides the most likely explanation of Andrea's decision to become
a vegetarian:
\(\bullet\) When Andrea was young, she was unrealistic about her future
behavior. Therefore, she did not act rationally.
\(\bullet\) Andrea was not working when she was young. After she graduated from
college and became employed, her income rose. We can conclude that for Andrea,
chicken, meatballs, and other meat products are inferior goods.
\(\bullet\) Social influences explain Andrea's decision to become a vegetarian.
More people, including celebrities from the entertainment field, have become
vegetarians. Andrea became a vegetarian because she now feels a kinship with
these celebrities, and being a vegetarian makes her appear to be fashionable.
