Emma was asked to volunteer at the senior center after school a few times a week. She was reluctant to do so because even though she loves seeing her own grandparents, she views the elderly as old-fashioned, senile, and embittered. Emma’s stereotypes of the elderly were most likely learned from:
a. mass media and popular entertainment
b. her parents
c. her grandparents
d. the elderly she meets on the street
e. other volunteer activities
