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 accuse your partner of bad behavior.
Update: You've accidentally falsely accused them before.
Example Output: strengthener

Example Input: Hypothesis: It's expected that you go out on your own when you reach adulthood.
Update: You are suffering from a phobia.
Example Output: weakener

Example Input: Hypothesis: It is understandable to be angry when someone owes you money.
Update: They only owe you fifty cents.
