A short educational flyer for students must explain (A) that yeast ferments carbohydrates to produce ethanol, (B) that 1 fl oz equals 2 tablespoons, and (C) how to compute number of standard drinks from volume and ABV. Which set of sentences best combines accurate science and the correct unit conversion for a student handout?

• A. Recommend that students avoid chemistry entirely, assume 1 fl oz = 1 tablespoon for easy math, and present a table of arbitrary drink equivalents that varies by venue.
• B. Include that yeast ferments sugars producing ethanol as a byproduct, state the conversion 1 fl oz = 2 tablespoons, and show the arithmetic: standard drinks = (volume in fl oz × ABV) ÷ 0.6, with an example calculation.
• C. Describe that yeast oxidizes ethanol to produce carbohydrates and claim 1 fl oz equals 3 tablespoons, then advise that estimating drinks requires only approximate visual judgment rather than precise calculation.
• D. Explain that fermentation is an industrial prediction method rather than a biological one, provide no unit conversion, and instruct students to use bottle labels as the only reliable method to measure drinks.

Answer: (B)
