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 bad to try to control other people.
Update: You're trying to stop someone from getting hurt.
Example Output: weakener

Example Input: Hypothesis: It's wrong to not be supportive of someone going through hard times.
Update: They are physically abusive toward others.
Example Output:
weakener
