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 it be a wise precaution to suggest that children and pregnant women stop taking fish-oil supplements?
NO.
