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 better to leave a public place than to cause a scene in it.
Update: You are protecting someone.
Example Output: weakener

Example Input: Hypothesis: It's acceptable for a parent to not approve of their child's friend.

Example Input: Hypothesis: It's wrong to be insincere to others.
Update: They are trusting, credulous sorts of people.
Example Output:
strengthener
