Answer:
A. In fact, elephants place such huge demands on their own environment, that in order to survive, they often come into conflict, with humans, who are competing for the same resources.

I believe the correct answer is the hollow in which the Wright home sat.
The farmhouse was situated away from the rest of the city, in a hollow where nobody liked visiting. This is why obviously Mrs. Wright had no contact with the outside world. Here's a quote from the text:
<em>Mrs. Hale: I stayed away because it weren't cheerful [...]. I've never liked this place. Maybe because it's down in a hollow and you don't see it from the road. I dunno what it is but it's a lonesome place and always was.</em><span><em> (101)</em></span>
