What was the primary purpose of Norbert Rillieux's invention, the multiple-effect evaporator?

• To improve the taste of sugar

• To make sugar production safer and more efficient

• To increase the size of sugar crystals

• To reduce the amount of sugarcane needed

How did the multiple-effect evaporator lower the production cost of sugar?

• By using less sugarcane

• By reducing the number of workers needed

• By capturing steam to heat the next stage and using a partial vacuum

• By increasing the boiling point of sugar

Explain why the timing of transferring sugarcane juice between kettles was crucial before the invention of the multiple-effect evaporator.

• It ensured the sugarcane juice was sweet enough

• It prevented the sugar from burning

• It was necessary to form sugar crystals properly

• It allowed the juice to cool down

What safety improvements did the multiple-effect evaporator introduce to the sugar refining process?

• It eliminated the need for boiling

• It contained the dangerously hot steam

• It used cold water instead of steam

• It required fewer workers
