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 presumptuous to tell someone else who they're allowed to host overnight.
Update: you're their parent
Example Output: weakener

Example Input: Hypothesis: You have a right to park where ever you like if you are there first.
Update: it's a free parking lot
Example Output: strengthener

Example Input: Hypothesis: You should be grateful for a gift.
Update: it was given to you by someone who doesn't have much to their name
Example Output:
strengthener
