EN： A non-defining relative clause (introduced by ', which...') adds supplementary, non-essential information about a preceding noun phrase. Because the subject 'Ava DuVernay's new documentary 14th' is already uniquely identified, commas are mandatory, separating the clause both prosodically and syntactically from the main assertion.
中文： 非限定关系子句（由“, which...”引导）为先行词提供补充性、非本质的信息。由于主语“艾娃·杜威纳的新纪录片《第十四修正案》”已经具体明确，因此必须使用逗号与主要子句隔开，在语音上需有停顿，语法上也不影响主要句意结构。

EN： The verb 'argued' introduces a nominal 'that'-clause containing an embedded present participle modifier: 'a clause [permitting involuntary servitude as criminal punishment] enabled...'.

EN： The documentary '13th' specifically targets the 'punishment clause' (or loophole) of the Thirteenth Amendment to the United States Constitution, which abolished slavery and involuntary servitude 'except as a punishment for crime whereof the party shall have been duly convicted.'

中文： 纪录片《第十三修正案》重点剖析美国宪法第十三条修正案中的“例外条款”（惩罚条款）。该条款废除了奴隶制与非自愿劳役，但保留了“作为犯罪惩罚且经合法定罪者”的例外。艾娃·杜威纳及诸多法律学者主张，这项历史漏洞促成了大规模监禁制度的扩张，使现代刑事司法体系在实质上延续了奴役体制的残余。

Board of Education to Obergefell v. Hodges) than almost any other constitutional provision.
