I said to myself they are both nouns, and my question was general
There is rarely such a thing as a "general" question on this forum! The only general question might be something like "What does the word teacup mean?" That is a word which has only one definition and the answer would easily be found in a dictionary. With that kind of question, context is not necessary as it really doesn't matter what the article/paragraph/sentence reads, a teacup is almost always just a teacup.
With the question you just posted, the words "facility" and "provision" both have several possible meanings and usages and it is only possible for us to comment on those usages if we know the context that you have in mind.
You may not understand the importance of context, but when you are asked over and over again to provide context for your questions, you should just take note and give context in future.
Thank you.
