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: You should always listen to someone even if you disagree with them.
Update: They won't take no for an answer and keep insisting.
Example Output: weakener

Example Input: Hypothesis: IT is okay to hold a pet's owner responsible for the actions of their pet
Update: The owner encouraged the pet's actions.
Example Output: strengthener

Example Input: Hypothesis: If there is something wrong with a bottle of wine it is smart to dump it out.
