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 expected that you know what your significant other prefers on a special occasion.
Update: Your significant other has plenty of everything already.
Example Output: weakener

Example Input: Hypothesis: It's okay for a roommate to move out if that's what they desire.
Update: You desire the roommate to move out, too.
Example Output: strengthener

Example Input: Hypothesis: It's understandable to have difficulty changing your behavior.
Update: There are many challenges to changing the behavior.
Example Output:
strengthener
