Step-by-step explanation:
Swimming in a bathing suit instead of street clothes is an example of a social norm.
Social norms are informal understandings that govern the behavior of members of a society.
They guide actions and behaviors that are considered acceptable in a social group or culture.
For instance, when it comes to buying clothes, teenagers often follow social norms, which could include considerations such as following parents' rules, or saving money, as they choose clothing that aligns with peer expectations and social standards.
Similarly, during special events, people may dress according to cultural expectations, but this is different from their everyday wear, further illustrating that social norms vary by context.
In sports and athletics, wearing specific attire, like swimsuits for swimmers or bodysuits for cyclists, is also regulated by social norms and also involves practicality, as it helps to minimize drag forces and conform to rules that maintain the integrity of the sport.
The trend of high-tech swimsuits in the Beijing Olympics highlighted the influence of technology on societal expectations and standards in sports.
So, the correct answer is 1. Physical activity
