Which type of media advertisement would most influence teens to try their first cigarette?

1. an Internet advertisement of a doctor explaining the risks of smoking
2. an Internet advertisement of a teen sitting alone smoking and looking sad
3. a television commercial of a 70-year-old talking about how sick he is after decades of smoking cigars
4. a television advertisement of twin sisters laughing and smoking while sitting on a bench

The television advertisement of twin sisters laughing and smoking while sitting on a bench would most likely influence teens to try their first cigarette. This type of advertisement portrays smoking as a social activity that is associated with happiness and bonding, which may appeal to teens who are seeking to fit in with their peers. Additionally, seeing people their own age smoking and having a good time may make smoking seem more desirable to teens.
