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 okay to like what you like no matter who created it.
Update: they stole it from the true inventor.
Example Output: weakener

Example Input: Hypothesis: You shouldn't rat people out.
Update: Especially if they aren't hurting anyone.
Example Output: strengthener

Example Input: Hypothesis: Classmates should help each other.
Update: They are put into groups to work on a project.
Example Output:
strengthener
