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 don't have to go on any trip that you don't want to.
Update: It is for your sick sibling.
Example Output: weakener

Example Input: Hypothesis: It's okay to cry after hearing something horrible.
Update: The horrible event happened to someone close to you.

Example Input: Hypothesis: It is rude to walk out in the middle of a service.
