To obtain a reliable $B \to η' X_s$ branching ratio, we calculate the $b\to s+g^*$ form factors up to the next-to-leading-logarithmic(NLL) approximation. We point out that the Standard Model prediction for $B\to η' X_s$ is consistent with the CLEO data, in contrast to the claims of some previous works.3 pages, LaTex2e, talk presented at EPS-HEP99, Tampere, Finland, 15-21 July 1999High Energy Physics - Phenomenologytext
