Sourdough bread is made by fermenting dough using naturally occurring lactobacilli and yeast. To maintain a sourdough starter, a baker must regularly "feed" the mixture with fresh flour and water. If the starter is kept at room temperature, it must be fed daily to keep the wild yeast active and healthy.
The writer is considering adding the following sentence to the paragraph:
"Yeast is also used in the fermentation process to brew beer and produce biofuels."
Should the writer make this addition?
- AYes, because it provides examples of other common uses for yeast.
- BYes, because it explains the chemical process of fermentation in detail.
- No, because it interrupts the focus of the paragraph by introducing uses of yeast unrelated to maintaining a sourdough starter.Cevap
- DNo, because it contradicts the paragraph's claim that sourdough starters need to be fed daily.
Cevap
The writer should not add the sentence because it interrupts the focus of the paragraph by introducing uses of yeast unrelated to maintaining a sourdough starter.
The correct decision is to exclude the sentence because the paragraph is narrowly focused on the maintenance of a sourdough starter. Mentioning the role of yeast in brewing beer and making biofuels shifts the focus away from baking sourdough, resulting in a minor distraction.
