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: You have the right to get upset at a partner that is ignoring you.
Update: You don't even know their reasoning behind it.
Example Output: strengthener

Example Input: Hypothesis: Apologies should be heartfelt and sincere.
Update: The apology is a legal requirement imposed by a judge.
Example Output: weakener

Example Input: Hypothesis: It is rude to call your mother names
Update: You are doing so in public.
