Here are the completed sentences with explanations: 1. **On** the other hand, each person wants to be popular **with** their friends. *Explanation:* "On the other hand" is a common phrase used to introduce a contrasting point. "With" is used to indicate that they want to be popular among their friends. 2. Our society puts too much pressure **on** teens, and its double messages are difficult **to** follow. *Explanation:* "On" is used with "pressure" to indicate who is affected by the pressure. "To" is used with "follow" to complete the infinitive form of the verb. 3. Don't become obsessed **with** your appearance! Your health and your mood **are** much more important! *Explanation:* "With" is used with "obsessed" to indicate what you are obsessed with. "Are" is used because "health and mood" is plural, so the plural form of the verb is needed. 4.

"Not" negates the statement, meaning it is not true that you need to be perfect.
