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: You shouldn't make sex bets against your friends.
Update: Everyone agrees and consents to it.
Example Output: weakener

Example Input: Hypothesis: It's bad to damage someone's personal property.
Update: You can't afford to replace it.
Example Output: strengthener

Example Input: Hypothesis: It's inconsiderate to others when you create a mess in the house.
Update: You're making a mess in the room they're trying to use.
