Task 1

• 0. careful, cheerful, helpful, brave. Brave doesn't fit because it is the only one that doesn't describe a person's character.
• 1. unkind, unfriendly, silly, unhappy. Silly doesn't fit because it is a synonym of the other three words.
• 2. honest, helpful, kind, careless. Careless doesn't fit because the other three words describe positive character traits.
• 3. lazy, talkative, sociable, boastful. Boastful doesn't fit because the other three words are neutral in meaning.
• 4. kind, clever, impolite, polite. Impolite doesn't fit because it has the opposite meaning to the other three words.
