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 is wrong to withhold information from a partner.
Update: The information may be so lacking in verification it isn't worth repeating.
Example Output: strengthener

Example Input: Hypothesis: It is wrong to spy on people.
Update: There's strong evidence that the people you're spying on are violent terrorists.
Example Output: weakener

Example Input: Hypothesis: Family members are expected to be a part of events.
