Which event is mentioned as illustrating the effects of discrimination on society?

The choice highlighting the 2011 London riots illustrates the effects of discrimination on society particularly well. The riots were largely fueled by a backdrop of social inequality, racial tension, and police-community relations. Triggered by the police shooting of Mark Duggan, the events escalated into widespread unrest that exposed deeper issues of disenfranchisement and frustration among marginalized groups in London. These riots revealed how feelings of discrimination and social exclusion can lead to civil unrest, making this event a representative example of the societal impact of discrimination.

Other options, while significant, relate to broader themes that might not directly illustrate the immediate effects of discrimination as specifically as the 2011 London riots. For instance, the Brexit vote involved a national debate on immigration and national identity but was not directly a response to a specific discriminatory act. Similarly, World War II, while encompassing genocide and discrimination on a massive scale, primarily focused on global conflict rather than a localized societal response. The civil rights movement, although it dealt explicitly with discrimination, was more about the struggle against these injustices rather than an instance illustrating immediate societal effects in a specific event like the riots.
