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 expected that people do not steal.
Update: The person is starving to death and can't afford food.
Example Output: weakener

Example Input: Hypothesis: You should always wish your roommates good luck.
Update: They have been supportive of you.
Example Output: strengthener

Example Input: Hypothesis: It is okay to move if you have trouble with animals.
Update: Moving will only provoke the animal to attack.
Example Output:
weakener
