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 wrong to make friends just to achieve something.
Update: The reason is trivial
Example Output: strengthener

Example Input: Hypothesis: You should be nice to children.
Update: The child is shoplifting from the store.
Example Output: weakener

Example Input: Hypothesis: It's okay to be upset if your sibling makes you late for school.
Update: He was just keeping you back to be annoying
Example Output:
weakener
