A learner chooses the first solely because its fibers are described as natural.

The learner wants to keep the design unchanged because classmates like its color.

A fictional food-product project aims to make an affordable snack with a defined serving yield and a texture acceptable to the intended users. The learner changes several ingredients at once, obtains a thicker mixture and attributes the result entirely to one ingredient. The cost record uses purchase-package prices without converting quantities, and a substitute ingredient has a different allergen declaration. User comments describe the texture but do not establish safety or nutritional adequacy.
