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: It's okay to like the people you like.
Update: They are bad people who will cause you pain.
Example Output: weakener

Example Input: Hypothesis: It's ok to grow apart from an old friend.
Update: They betray your trust.
Example Output: strengthener

Example Input: Hypothesis: When you are at someone else's house for a party, it's rude to play with dangerous toys.
