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 shouldn't tell others to divorce.
Update: They say the only problem is that they feel vaguely unfulfilled.
Example Output: strengthener

Example Input: Hypothesis: It's wrong to disturb other people's property.

Example Output: strengthener

Example Input: Hypothesis: You should help your family when they are in trouble.
