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

Hypothesis: It's good to watch out for friends and express disapproval of predatory relationships they tell you they're in.
Update: You are really close to them
strengthener

Hypothesis: Your partner should not threaten to leave you over your appearance.
Update: Your weight has become a health issue and they don't want to watch you kill yourself with lack of self care.
weakener

Hypothesis: It's good to stay in touch with your siblings.
Update: They are your best friends

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.
