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 rude to purposefully humiliate someone in a social setting
Update: You have the backing of others at the social event.
Example Output: weakener

Example Input: Hypothesis: It is right to contact the authorities if someone is breaking the law.
Update: Someone is hurting another badly or putting them in grave danger.

Example Input: Hypothesis: It's rude to constantly make one person do random drug tests if others aren't being treated the same way.
