Mr. Nuttel's expectations about the interaction he is about to have are primarily influenced by his feelings of uncertainty and apprehension about visiting strangers in the countryside. The correct response is:
He does not expect the visit among strangers to have much value.
This expectation is shaped by his doubts about whether formal visits will help his nervous condition and by his sister's comments that suggest he may isolate himself rather than engage with others, leading him to feel skeptical about the social interaction he is about to have.
