Final answer:
A crowd is more likely to get out of control at an event with a high potential for heightened emotions or specific objectives such as a hockey game, rock concert, or a protest rally, which correspond to the three options provided.
Step-by-step explanation:
A likely place for a crowd to get out of control? According to Turner and Killian (1993), there are four types of crowds: casual, conventional, expressive, and acting crowds. An acting crowd, which forms with a specific goal or action in mind, such as a protest or riot, often carries a higher potential for becoming out of control due to the heightened emotions and objectives of the participants. Therefore, among the options provided: a hockey game, a rock concert, and a protest rally, the correct answer is 'D. All of the above' as each event represents a scenario where crowds form for different reasons but can escalate to the point of losing control due to various factors like strong emotions, competition, or political fervor.
