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 is wrong to hold a grudge over something someone said.
Update: what they said was said in jest
Example Output: strengthener

Example Input: Hypothesis: It is reasonable to fire someone who does not do their job.

Example Input: Hypothesis: Communication is expected in a relationship.
