Korean subject object predicate

As long as the subject is nominal, such as? ,? ,? , what else? In this way, adjectives become nominal.

I don't think there is any problem here.

What this object says is

Put forward and use interrelated things to explain actions and the objects of actions.

Focus on the last object here,

For example, if you eat, here eating is the predicate, and eating is the object of your actions.
