With no explanation, label text_A→text_B with either "DON'T KNOW", "NO" or "YES".
text_A: Smith's career was cut short by the Great Depression, which nearly put the recording industry out of business, and the advent of sound in film, which spelled the end of vaudeville. She stopped performing, however. The days of elaborate vaudeville shows were over, and Smith stopped touring and occasionally singing in clubs. In 1929, she declined to appear in a Broadway musical, "Pansy". The play was a flop; top critics said she could have been its only asset.
text_B: Was Smith in any performances after films had sound?
NO.
