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 is rude to ignore your friends
Update: They crashed your car and didn't pay for the damages.
Example Output: weakener

Example Input: Hypothesis: It's understandable to be upset if a girl you are interested in is still influenced by her ex.
Update: she leads you on
Example Output: strengthener

Example Input: Hypothesis: Animals should never be in the bed.
Update: They are well behaved and it is OK with any humans who sleep in that bed.
Example Output:
weakener
