以下两段都是“中华考试网”中“2019上半年CATTI二级笔译考试真题英文翻译中文（第二篇）”中的内容。
The scientific objectives of the research result in a better knowledge and understanding of the history of the site, and its inhabitants that constitute a rich exceptional legacy of the intangible heritage.
请问粗体字中的legacy和heritage都有“遗产”的意思，同时用是否重复了？
The site integrity however, is put under dual pressures: Endogenous: exerted by more than 100,000 inhabitants distributed over 112 historic settlements scattered over the site, who constantly try to expand their dwelling areas; exogenous: related to the proximity of the town of Siem Reap, the seat of the province and a tourism hub.
请问粗体字是否the town of Siem Reap的同位语，该怎么样翻译呢？
大定义中包括小定义，语义上需要重复这个定义，但语法上用近义词或同义词防止重复名词。这是非常正常的。比如无形遗产中的特殊遗产，语义上需要重复遗产，但语法上用不一样的词表达遗产，防止重复同一个名词。
the seat of the province and a tourism hub 是同位语。翻译为省府所在地和旅游中心。
