Which set of words could be required as signal words on a pesticide label?

• A. Danger, Caution, Warning
• B. Caution; Danger; Warning
• C. Caution, Danger, Hazard
• D. Warning, Notice, Caution

Answer: (B)

Signal words on pesticide labels tell you how dangerous the product is in terms of acute toxicity. There are three standard signal words: Danger for highly toxic products, Warning for moderately toxic, and Caution for slightly toxic. A label could require any of these words depending on how toxic the product is, so the set that includes all three—Caution, Danger, and Warning—captures all the possible signal words that could appear. Words like Hazard or Notice aren’t used as signal words on pesticide labels, so they don’t fit.
