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: It's bad to try to control other people.
Update: You're trying to stop someone from getting hurt.
weakener

Hypothesis: It's fine to cancel plans with someone.
Update: You have an emergency to deal with.

Hypothesis: It is okay to stick up for yourself
