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 okay to want peace and quite so you can rest when others are disturbing you.
Update: the others have a good reason to.
Example Output: weakener

Example Input: Hypothesis: It is good to acknowledge when people change for the better.
Update: Acknowledging the change encourages them to keep improving.
Example Output: strengthener

Example Input: Hypothesis: It's okay to not want to say goodbye to a beloved pet.
Update: The pet is very sick and you have had it for 15 years.
Example Output:
