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 awkward to watch interaction between parents and children on social media.
Update: you are the cause.
Example Output: weakener

Example Input: Hypothesis: You shouldn't associate with family members that don't love you.

Example Input: Hypothesis: Feeling threatened by a partner's social life is natural.
