Which of the following is not a type of quick bread?

Bagels are indeed not classified as a type of quick bread. Quick breads are typically made using leavening agents that allow the dough to rise quickly—like baking powder or baking soda—rather than yeast, which requires time for fermentation. Biscuits, muffins, and corn bread all fit this category since they utilize these fast-acting leavening agents and are prepared without the lengthy process of yeast dough.

On the other hand, bagels are made from a yeast dough that is boiled before baking, contributing to their dense and chewy texture. This preparation process distinguishes bagels from quick breads, which are characterized by their convenient and rapid preparation methods. Understanding this classification helps in distinguishing between different types of bread and their preparation methods.
