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 shouldn't expect your old friends to acknowledge you after a long time has passed.
Update: You have lived near your old friends for years and did not reach out to them.
Example Output: strengthener

Example Input: Hypothesis: You shouldn't go to parties if you are just going to be quiet.
Update: The party is thrown by a fraternity.
Example Output: strengthener

Example Input: Hypothesis: It's understandable that sometimes, people change, and outgrow each other.
Update: You always have love for that person
Example Output:
weakener
