Bakeries use yeast in bread-making because it – (1) makes the bread hard (2) makes the bread soft and spongy (3) enhances the food values (4) keeps the bread fresh
(2) makes the bread soft and spongy Explanation: Bread is usually made from wheat-flour dough that is cultured with yeast, allowed to rise, and finally baked in an oven. The fermentation due to yeast makes the bread soft and spongy.
