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: People are expected to take care of their family.
Update: they are very in need of help.
Example Output: strengthener

Example Input: Hypothesis: You should never violate someone's right to privacy online
Update: That person trusts you to respect their privacy.
Example Output: strengthener

Example Input: Hypothesis: It's understandable if you do not want to spend time with your parents.
Update: They are very old and have little time left.
Example Output:
weakener
