1. If you mix red and blue, you **get** purple. Type 0 *Explanation:* This is a zero conditional, used to express general truths or facts. The tense is simple present in both clauses. 2. If I had a spare ticket for the festival, I **would give** it to you. *Explanation:* This is a second conditional, used to talk about hypothetical or unlikely situations. The tense is simple past in the 'if' clause and 'would + base form' in the main clause. 3. We'll be there at four, unless we **run into** traffic. *Explanation:* This is a first conditional, although 'unless' replaces 'if not'. It's used to talk about possible future events and their consequences. The tense is simple present after 'unless' and 'will' in the main clause. 4. If she **hadn't seen** them with her own eyes, she would never have believed how beautiful the sculptures were. *Explanation:* This is a third conditional, used to talk about hypothetical past events and their consequences. The tense is past perfect in the 'if' clause and 'would have + past participle' in the main clause. 5. **Will** you **pick up** my suit from the cleaner's if it's on your way? *Explanation:* This is a first conditional, structured as a question. It's used to talk about possible future events and their consequences. The tense is simple present in the 'if' clause and 'will + base form' in the main clause. 6. I wouldn't wear jeans to the dance if I **were** you. *Explanation:* This is a second conditional, used to give advice or imagine a hypothetical situation. The tense is simple past in the 'if' clause and 'would + base form' in the main clause. The use of 'were' is common with 'I' in second conditionals to express an unreal condition.
