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 a concern, however, because heavy metals (mercury, lead, nickel, arsenic, and cadmium) selectively bind with proteins in the fish oil, while such an accumulation of metals is highly unlikely in the flesh.
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.
