Fermentation of which gives ethanol?
Think it through first, then pick an option.
- a fish
- b meat
- c rice
- d milk
Answer and explanation
Correct answer: c rice
According to the book, starch from rice, wheat, potato and maize ferments to alcohol (ethanol); cooked rice is rice starch.
Why the other options are wrong
- a fish: Fish is mostly protein; fermentation makes ethanol from starch (rice, wheat, potato, maize).
- b meat: Meat is protein too; ethanol needs starch or molasses.
- d milk: Milk is not on the book's list for fermentation; ethanol comes from starch.
