The paragraph contains an analogy.
Explanation:
An analogy refers to when we draw up a comparison between two separate things or situations, to explain or clarify something. If certain significant aspects of two situations (even though the situations themselves may bevery different) are somewhat similar, an analogy can be drawn between them.
In the given paragraph, an analogy is drawn between two scenarios: One, wanting pizza for dinner but having chili since the other family members wanted it and two, similarly giving up certain rights for the good of a community or group.
Another popular example of an analogy is: Life is like a box of chocolates; you never know what you're going to get.
Here, our lives are being compared to an assorted box of chocolates, wherein lies the analogy.
