定语从句是就近原则吗？

Question

Ideally, anel members have a knowledge of international trade and are either lawyers or trade specialists who have been active in the field.
很大的问题就是
who have been active in the field 是修饰specialists（就近原则） 还是lawyers，specialists两个词都修饰？

Answer 1

两个都修饰，这个不是就近原则关系代词和先行词指的是相同的对象。他们的数量是一致的。

Answer 2

就近原则。
这句话就是修饰specialists得。
