- Here are the instructions for you to follow.
The verb «follow» directly related to the Headword «instructions»; for- subordinator introducers one more subject in the sentence –You – it seems to be a perfect For-infinitival Relative Clause.
- These are climate changing efforts for forest fires to be kept that low.
The verb «kept» relates not to Headword «efforts» but rather to one more added subject introduced by for- subordinator forest fires, hence in trying to keep the form of For-infinitival RC, I put in the Passive Form.
I might be wrong, but my understanding is that if a verb in the subordinate clause relates to Headword and NEW subject is introduced, then it is clear case of For-infinitival Clause.
Whereas, if it is this added Subject that the verb in Subordinate Clause relates to – it is not longer FOR-RC, but Purpose Adjunct with modality of obligation or necessity.
Am I right in my conclusion?
