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 tell people what not to do.
Update: they are doing something that's wrong.
Example Output: weakener

Example Input: Hypothesis: You shouldn't get mad at your siblings.
Update: Your siblings are nice and do nothing wrong to you.
Example Output: strengthener

Example Input: Hypothesis: You are not required to hang out with your family.
Update: You know that your parents invited your ex husband.
Example Output:
strengthener
