## Step 1<br />The task involves using the comparative form of adjectives in sentences. In English, the comparative form of adjectives is used to compare differences between two objects or groups. <br /><br />## Step 2<br />For most short adjectives (usually those with one or two syllables), the comparative is formed by adding "-er" to the end of the word. For example," becomes "slower", "big" becomes "bigger", "expensive" becomes "more expensive", "modern" becomes "more modern", and "dirty" becomes "dirtier".<br /><br />## Step 3<br />For longer adjectives (usually those with three or more syllables), the word "more" is used before the adjective to form the comparative. For example, "good" becomes "better", "nice" becomes "nicer".<br /><br />## Step 4<br />Some adjectives have irregular comparative forms. For example, "good" becomes "better", "bad" becomes "worse".
