Consider the following pairs regarding ethanol blending terminology and the characteristics of each fuel blend:

Pairs

1. E10 — A petrol-ethanol blend containing up to 10 per cent ethanol by volume, compatible with most conventional unmodified petrol vehicles
2. E85 — A high-ethanol blend requiring vehicles specifically designed and certified for it; compatibility with E20 alone does not establish suitability for this blend
3. E100 — A fuel consisting entirely or predominantly of ethanol, used in flex fuel vehicles certified for the highest ethanol content range
