"When that crisis occurs, the actions that are taken depend on the ideas that are lying around."
(Milton Friedman.)
the actions that are taken depend on the ideas that are lying around - a main clause;
When that crisis occurs - a subordinate clause;
the actions that are taken - a subject;
depend on - a predicator (main verb of the sentence, a transitive phrasal one);
the ideas that are lying around - a direct object.
