Answer: Culture
Explanation: I say this because of the tone with which she asked, "Are you going out today?" and her "today" sounded as if she couldn't believe it. Furthermore, when she said, "Hija, the president has been killed. We must show respect. He was a great man. Come to church with me tonight." I believe she felt that going out to places other than church was disrespectful, and this type of conflict occurs when someone has a cultural belief.
HOPE THIS HELPS.
