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 should always clean up something if you are supposed to do it.
Update: You made the mess in the first place.
Example Output: strengthener

Example Input: Hypothesis: You should stay in touch with your friends.

Example Input: Hypothesis: It's understandable to want a clean break with an ex.
