Contrast, or comparison, is a method used to highlight the differences between two or more subjects. This technique helps to clarify characteristics, qualities, or features that set them apart. For example, comparing cats and dogs can reveal differences in behavior, care needs, and social interactions. In writing and analysis, contrast can enhance understanding by providing a clearer picture of each subject. By examining how apples differ from oranges, one can appreciate their unique flavors, textures, and nutritional values. This approach is valuable in various fields, including literature, science, and everyday decision-making.
