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 rude to make someone wait.
Update: They were on time.
Example Output: strengthener

Example Input: Hypothesis: It's good to fill in for coworkers that need help.
Update: You don't know how to do their job and would only make it worse
Example Output: weakener

Example Input: Hypothesis: If someone falls in front of you it is polite to help them up.
Update: The person who fell is a child and might get trampled on if you don't help him.
Example Output:
strengthener
