C. She has wanted to move west for several years, and now he's taking her there.
Answer: 2 and 5
Explanation: Part 1 is only a description of the action, and parts 3 and 4 introduce details from the character's past that enrich the narrative, but don't build anticipation. Part 2 introduces some anticipation in the last words "...he lay perfectly quiet and listened," which evokes in the reader a feeling of expectation for a relevant piece of auditory information. Part 5 has an even more intense effect, concentrated in the words "...he might never know again," which project an ominous feeling that events are about to unfold in the character's life.
