After I had the piano tuned, I opened the lid and touched the keys. It sounded even richer than I remembered. Really, it was a very good piano.

What is the author’s purpose in using sensory detail to describe the piano?

a to reveal that the piano was more expensive than the narrator had believed

b to show that the piano was louder than the narrator remembered

c to reveal that the narrator is happy to play piano after so many years

d to show that the narrator understands the value of the piano now that she is older
