I'm an ESL teacher and one of my adult students and I recently read this article in class. He and I were stumped by the structure of the very last sentence:
Toshimitsu Motegi, minister of economic and fiscal policy, said Friday that the Cabinet Office would need to correct figures on employee compensation, which it publishes along with GDP every three months.
My student understood the gist of the sentence after I pointed out that "which it" refers to "figures on employee compensation", but he still wanted to dig deeper into the grammatical structure of this sentence. I wasn't positive, so I told him I would look into it and get back to him with a breakdown for next time.
We both thought it might something related to relative or essential/non-essential clauses, but looking into examples of those online I'm not so sure.
Any help or leads are appreciated.
