I don't understand the usage of "being" in these sentences. Is this some kind of special way to use it? I think this is the usage called "reduced adjective clause" but in that rule we omit the "be form of the verb" if there is one.
Example for the rule I talked about:
He is the student who is responsible for making a trouble in the class.
Reduced version =
He is the student responsible for making a trouble in the class.
The sentences that I don't understand:
