Answer:
I think it is A
Explanation:
It really isn't clear without the textual evidence, but I think A firstly because the other ones make it sound like the person writing about his experience in Alaska is too full of himself (most tests don't include that type of things).
Secondly, if it were to be a survival thing it wouldn't have been to encourage readers to go there, and in general most books or stories aren't substitutes for ads.
this is my theory for A, but it might not be accurate.
