Answer: B) old age and isolation
Explanation:
The sentences provided describe Will as someone who suffers from the pain and inactivity that comes with old age. Furthermore, they show he hasn´t left his room in weeks, and only leaves it to go on a walk by himself, meaning that he´s also lonely.
The tone of these sentences is rather tense, which can lead us to infer that the conflict will have something to do with the character´s loneliness in his old age.
