[1] Sourdough bread relies on a wild yeast starter rather than commercial baker's yeast. [2] This starter, a fermenting mixture of flour and water, captures wild yeasts and beneficial bacteria from the environment. [3] Over time, these microorganisms produce carbon dioxide and lactic acid, giving the bread its characteristic rise and sour flavor. [4] Many commercial bakeries prefer using dry active yeast because it is faster and more predictable. [5] Once the starter is active, it must be regularly fed with fresh flour and water to keep the yeast alive.

Answer
Deleted, because it interrupts the paragraph's discussion of how wild yeast starters are developed and maintained.
The correct answer is to delete the sentence because it interrupts the paragraph's discussion of how wild yeast starters are developed and maintained. The paragraph describes the biology, function, and upkeep of wild yeast starters, and introducing commercial bakeries' preferences distracts the reader from this explanation.
