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 not nice to take advantage of people's ignorance in a negotiation.
Update: acheiving your desired outcome is critical to your job
Example Output: weakener

Example Input: Hypothesis: You shouldn't tell other people to "fuck off."
Update: They cut you off in traffic
Example Output: weakener

Example Input: Hypothesis: It's good to be flexible in plans, even when you're vested in the original.
Update: Your original plans were to pick up a friend at the airport.
Example Output:
