The way we consume and acquire it, the fashion in which it gets cooked and by whom, who is invited to the table and who eats first, such tradition is a form of nonverbal communication – a social code abundant with meaning.

译文：我们消费和获取食物的途径、烹饪食物的方式、厨师是何人、受邀宾客都有谁，以及谁最先动筷子，这些传统是一种非语言的交流——一种富有含义的社交准则。

曹老师好，

1.原文中by whom 前面有部分被省略了？还原后应该是：The way we consume and acquire it, the fashion in which it gets cooked and the fashion in which it gets cooked by whom, who is invited to the table and who eats first, such tradition is a form of nonverbal communication – a social code abundant with meaning.  是这样吗？

2.such tradition 指代 (1) the way we consume ... , (2) the fashion …, (3) who is invited…, (4) who eats first，所以，such tradition可以称作是这4部分的“同位语”吗？其次，如果指代这4部分，tradition 为何不用复数？

谢谢老师。
