英文文法疑難

Q.: given are two figures concering criminality in Britain.點解given放頭:
given = past participle, used as an adjective.
原句= two figures concerning criminality in Britain are given .
In this sentence, given is placed at the beginning for emphatic purpose, with a inversion.
given =過去分詞, 用作形容詞, 放在句前, 作強調式, 此句要作倒装
= 提供了2個有關英國罪案數字。
e.g. His argument is shown below.
Shown below is his argument.

given 的意思有幾個。
例如: (adj) 已知的 / 假設的等
E.g. The given diameter being 6cm. Find the are of the circle.

亦可解作 (prep.) 如果有/假如/考慮到等等
E.g. Given the same treatment again, he is sure to get well.

還有 (n.) 假設的事實/已知的事實
E.g. It is taken as a given.

而你這裡的 given ，我猜是 (prep.) 如果有等的意思或是 (n.) 假設的事實等的意思。
