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 understandable to want to avoid greeting people.
Update: Unless it's your wedding.
Example Output: weakener

Example Input: Hypothesis: It's wrong to create problems for other people.
Update: They truly deserve it because they did something very bad and it's the only way they'll learn.
Example Output: weakener

Example Input: Hypothesis: Reporting someone to the police can ensure that they change their behavior.
Update: they are very young.
Example Output:
