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 never be rude to disabled people.
Update: You have medical training.
Example Output: strengthener

Example Input: Hypothesis: It is good to talk to your friend about their behavior if they are being manipulative.

Example Output: weakener

Example Input: Hypothesis: You should not joke around with colleagues.
Update: You have known your coworkers for a long time.
