Although there are no options attached, we can comment on the following.
Norah is invited to a party at a peer’s house. She learns that there is going to be drinking at the party but does not want to drink. Her friends are excited to drink and are talking about getting drunk together at the party, encouraging Norah to do the same. Norah is worried about the pressure they are going to exert on her to force her to drink with them.
At that age, there is always the social pressure of other students to do the same things they do and consider to be the right thing to do for that age. Norah is afraid that if she attends the party, she will be force bu her friends to drink, and she doesn't like that. That social pressure is the one that many times affects young people that do not want to smoke, drink, or do any other things that could have serious consequences in their lives.
