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 wrong to make friends just to achieve something.
Update: The reason is trivial
Example Output: strengthener

Example Input: Hypothesis: It's not okay to say bad things over something head when they can't understand you.
Update: you are being unfair and mean to them.
Example Output: strengthener

Example Input: Hypothesis: It is wrong to throw away things that don't belong to you.
Update: you have bought them a replacement.
Example Output:
weakener
