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: sometimes it is ok to give people a taste of their own medicine
Update: they are always being a rude person
Example Output: strengthener

Example Input: Hypothesis: It's wrong not to get your children haircuts.
Update: they feel socially awkward with long hair
Example Output: strengthener

Example Input: Hypothesis: It's OK to ask for gifts you'd like for Christmas.
Update: you ask for expensive items that you know would be difficult for the person you are asking to afford.
Example Output:
weakener
