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 good to volunteer.
Update: Unless you are only doing it to show off.
Example Output: weakener

Example Input: Hypothesis: You shouldn't do things that cause your parents to become so angry that they behave irrationally
Update: Your parents have unreasonable expectations.
Example Output: weakener

Example Input: Hypothesis: It is understandable to be upset with someone who ask to use something you are using.
Update: They have one of their own to use.
Example Output:
strengthener
