Hi. Although you submitted a text, you did not submit any questions related to it. This prevents me from giving you any answers. However, when searching for your text on the internet, I was able to find it in a question that asked for the central idea of this text to be explained. If that's the case with your question, I hope the answer below can help you. If this is not the case with your question, the explanation below will make you better understand the text above, which will make your search for answers easier.
The main idea of a text is the message that the author expects you to understand after reading. After reading the text above, we can see that the main idea is the idea of how participation in a jury should be understood as something important and essential in our lives as citizens. This is because, according to the interpretation of the text, the author shows that the participation of a jury gives an example to children and young people, about how this participation is important and it is a social duty that allows the exercise of justice in the country. This is a duty to the country, society and citizens. Thus, when a citizen refuses the call to participate in a jury, he erases all the importance that this act means for everyone's life and acts as if the jury were something trivial, setting a bad example for the next generations.
