With no explanation, label text_A→text_B with either "DON'T KNOW", "NO" or "YES".
text_A: none of the great confederations of steppe warriors was ethnically homogenous, and the same name was used by different groups for reasons of prestige, or by outsiders to describe their lifestyle or geographic origin. [...] 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: Did all steppe warriors have the same geographical roots?
NO.
