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 rude to stop talking with acquaintances.
Update: They are using filthy language.
Example Output: weakener

Example Input: Hypothesis: It's good for a business to donate to charity rather than waste money on a party.
Update: Morale is low at the company and a party will help retain employees.
Example Output: weakener

Example Input: Hypothesis: It's good to be honest with parents.
