Resistance to authority
C
Drop in performance during change
D
Confusion over adopter roles
Correct Answer: C
A: Incorrect – That refers to cumulative adoption.
B: Incorrect – Resistance is part of the dip, but not the full concept.
C: Correct – It’s a temporary performance decline during early implementation.
D: Incorrect – Adopter confusion is not the focus.
Q13
Which of the following best describes the role of mass media in diffusion?

B
Peer negotiation and consensus
D
Direct persuasion by managers
Correct Answer: C
A: Incorrect – That describes interpersonal channels.
B: Incorrect – That aligns with collective decision-making.
C: Correct – Mass media spreads awareness widely and quickly.
D: Incorrect – That relates more to authority decisions.
Q14
Which type of innovation decision is most susceptible to internal power dynamics?
Correct Answer: B
A: Incorrect – Optional decisions are made individually.
B: Correct – Authority decisions involve top-down mandates, often linked to power structures.
C: Incorrect – Collective decisions involve shared consensus, not just authority.
D: Incorrect – Contingent decisions depend on others but not necessarily on authority.
Q15
Which adopter group helps bridge early and late adopters through cautious but timely adoption?
Correct Answer: B
A: Incorrect – They lead innovation but aren’t the bridge group.
B: Correct – The early majority adopts just before average and reduces uncertainty.
