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 shows character to step up to an unforeseen challenge.
Update: The challenge is impossible and a losing proposition.
Example Output: weakener

Example Input: Hypothesis: Getting upset is normal and common.
Update: There's no valid reason to be upset.
Example Output: weakener

Example Input: Hypothesis: It's ok to take trips without your significant other.
Update: You are both on vacation.
Example Output:
strengthener
