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

Hypothesis: You shouldn't accuse your partner of bad behavior.
Update: You've accidentally falsely accused them before.

Hypothesis: It's expected that you arrive places on time.

Hypothesis: It's good to give your boss advance notice when you will be quitting.
