Final answer:
Sitcoms often use humor to discuss controversial topics, which allows for a less serious approach that can open up conversations and increase awareness among viewers.
Step-by-step explanation:
Sitcoms often 'get away with' talking about controversial topics because they use humor to diffuse tension (b). By incorporating humor into their narratives, sitcoms create an environment where sensitive issues can be presented in a less serious and more palatable manner. Comedy has a long tradition of dealing with practical choices over ethical ones, depicting common people in various - often humorous - situations that resonate with larger audiences. Shows like The Daily Show and The Simpsons tackle controversial topics through a comedic lens, making viewers more receptive.
Furthermore, sitcoms have evolved over time to feature less traditional family structures, reflecting and sometimes challenging societal norms. By portraying a wide range of family dynamics, they open up conversations on topics that might otherwise be considered taboo. Also, according to research, viewers of political comedy shows may actually be more politically knowledgeable, indicating that humor can be an effective vehicle for raising awareness and understanding of complex issues.
