With no explanation, label text_A→text_B with either "DON'T KNOW", "NO" or "YES".
text_A: zero of the great confederations of steppe warriors was ethnically homogenous, and different names were used by different groups for reasons of prestige, or by outsiders to describe their lifestyles or geographic origins. [...] It is therefore futile to speculate about identity or blood relationships between H(s)iung-nu, Hephthalites, and Attila's Huns, for instance. All we can safely say is that the name "Huns", in late antiquity, described prestigious ruling groups of steppe warriors.
text_B: Would steppe warriors who were strangers to each other be likely to have common ancestors?
NO.
