Final answer:
The author's questions in the excerpt engage readers, stimulate critical thinking, and challenge assumptions about bread, making the questions a key feature in contributing to the essay's meaning.
Step-by-step explanation:
The author's use of questions in the excerpt from the essay "Bread" serves to engage the reader and challenge their assumptions about the importance and availability of bread. Rather than providing straightforward information or conclusions, the questions stimulate critical thinking and encourage readers to reflect on their personal experiences and beliefs regarding the subject of bread.
This interactive style is a common literary device that adds depth to the reading experience by prompting introspection and analysis, contributing significantly to the essay's meaning. While most recognize the enjoyment of freshly-baked bread, with its light and fluffy texture thanks to yeast fermentation, artisanal bread-making historically was a complex process with many failed attempts due to the unpredictable nature of capturing wild yeasts.
