With no explanation, label text_A→text_B with either "DON'T KNOW", "NO" or "YES".
text_A: Heavy metal poisoning from consuming fish oil supplements is highly unlikely, because heavy metals (mercury, lead, nickel, arsenic, and cadmium) selectively bind with protein in the fish flesh rather than accumulate in the oil.
text_B: Would a warning label that reminds users to take fish oil supplements only in their recommended doses be a sufficient precaution (or perhaps even an unnecessary one) given the level of risk?
YES.
