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 not okay to do something that could hurt or make someone else jealous.
Update: you are attacked first.
Example Output: weakener

Example Input: Hypothesis: Not everyone wants a pet in their house and that choice should be respected.
Update: The pet is making a mess in the house.
Example Output: weakener

Example Input: Hypothesis: It's fine to notify your boss if a co-worker is breaking rules.
Update: they are doing so only due to unusual circumstances beyond their control.
Example Output:
weakener
