As the US court is long being criticized as being historically underrepresented by judges whose experience includes battling the government in court, Joe Biden’s team is now looking to appoint more judges who used to challenge the government, with an aim to bring more substantive diversity to the federal bench.
问题：
1. long 和 historically 是否语义重复？
2. substantive diversity 是批评者提出的概念，像我这样用在Biden’s team发出的动作（aim）里面，是否算是张冠李戴、偷换概念？
3. 句子是否太长，是否应该断句？
