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 rude to mess up someone's plans.
Update: They worked hard on the plans
Example Output: strengthener

Example Input: Hypothesis: Friends should be interested in similar things.
Update: You like spending time together.
Example Output: strengthener

Example Input: Hypothesis: It's OK to cut someone out of your life for lying.
Update: You have a long history together and they were always honest before then.

weakener
