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 okay to not trust someone that has hurt you in the past.
Update: They have shown you that they have changed.
Example Output: weakener

Example Input: Hypothesis: You should be kind to animals.
Update: The animal has become rabid and is about to attack.
Example Output: weakener

Example Input: Hypothesis: It's okay to want to celebrate a birthday late if you have other plans.
