She must live close to where she works because she walks to work.
This sentence is given as an example of "must" being used for deduction in the present. However, when I read the sentence, I thought it might not only refer to "a deduction" but it can also refer to "a necessity".
So, the sentence can have 2 meanings for me:
1-It is a deduction. And it means I suppose she is living somewhere close to her workplace, because she comes to workplace on foot. So, she can't be living far away.
2-I feel sorry for her, because the poor woman walks to work which must be tiring for her. She is poor, so she tries not to take the bus. Instead, she walks to work every day, because she wants to save that money to buy something else. So, I feel sorry for her and I think it is a must for her to find another house to live in, and I say "She must live close to where she works because she walks to work."
I am not quite sure. Is the second meaning not likely?
