In this task, you are given a hypothesis and an update. The hypothesis sentence is a statement that speaks of a socially normative behavior. In other words, it is a generalizing statement about how we expect people to behave in society. The update provides additional contexts about the situation that might UNDERMINE or SUPPORT the generalization. An undermining context provides a situation that weakens the hypothesis. A supporting context provides a situation that strengthens the generalization. Your task is to output 'strengthener' or 'weakener' if the update supports or undermines the hypothesis, respectively

Example Input: Hypothesis: It's okay to want to be back home after you have been away.
Update: You have been gone for a long time.
Example Output: strengthener

Example Input: Hypothesis: It's okay to be upset when a friend says something that is hurtful towards you
Update: The friend has apologized for what they have said
Example Output: weakener

Example Input: Hypothesis: It is wrong to make the person you are dating miss their dentist appointment.
