Answer:
undeveloped, or time
Explanation:
The definition of primitive is old or ancient and since no other word means that, so for that reason, I would go with undeveloped, or time.
this question is a tricky one though because the words don't really describe primitive, but what you can get from the passage, is that even though the campsite had no running water they still had a great time and the scenery was beautiful.
Another thing is since it is ancient it took time to become ancient so that's what knocks out the answer choice undeveloped.
I am unsure about this answer, and don't have a very good explanation so, I wish you the best of luck with this question I just gave my best guest.

1-4 look correct to me.
for #5, you are correct that to come is not a prepositional phrase because there is no object. If I were you, I'd leave it alone and keep the one next it. all others look correct.
