With no explanation, label text_A→text_B with either "DON'T KNOW", "NO" or "YES".
text_A: Pottery making began in the 7th millennium BC. The earliest forms known, which were found at the Hassuna site, were hand formed from slabs, undecorated, low-fired pots with a primitive glaze made from reddish-brown clays, but it is unknown if even earlier, unglazed forms may have been lost to the elements. Within the next millennium, wares were decorated with elaborate painted designs and natural forms, incising and burnished.
text_B: Does the passage imply that even the earliest uses of pottery had some sort of aesthetic or even food-related purpose that would necessitate some kind of sealant around the fired clay?
YES.
