Good is an adjective, well is an adverb.
When you are talking about how you are doing (verb), you would use the word "well" (adverb) because it describes the verb.

I would choose a. Simply because the author talks about it as if it's all that really ever existed and that nature cannot take over what it is not. However, it goes on about seeing how erosion and rot can affect such things and tries to compare it to things in nature as if it were nature itself.
In my opinion, the correct answer is A. <span>It is the predicate of the sentence. The verb phrase in this sentence is "are invited to stay". It is a phrase and not just a regular verb because it has its own modifier ("to stay") that describes or completes it, providing additional information. This predicate is in passive voice because the subject is actually the one that undergoes the action (instead of doing it, as subjects normally do), whereas the agent (the one who actually does the action) is unmentioned here.</span>
