Answer:
The detail in this excerpt that further complicates Neto’s conflict is The school board does not respond to Neto.
Step-by-step explanation:
In the excerpt, we have some lines that clearly demonstrate that the school board does not respond to Neto when he said "Only one of them looked like he was really listening. When I was finished, they thanked me for coming, but they didn't say they would do anything about it." this means that even when he tried his best and explained his perspective of the situation nobody actually cared about his speech.
