Teacher:In this task, you are given a premise, a hypothesis, and an update. The premise sentence describes a real-world situation and is always assumed to be true. The hypothesis sentence describes an assumption or inference that you might make about that situation having read the premise. The update provides additional information about the situation that might weaken or strengthen the hypothesis. A weakener is a statement that weakens the hypothesis, that is, it makes you much less likely to believe the hypothesis is true. A strengthener is a statement that strengthens the hypothesis, that is, it makes you much more likely to believe the hypothesis is true. Your task is to answer with 'strengthener' or 'weakener' if the update strengthens or weakens the hypothesis, respectively.
Teacher: Now, understand the problem? Solve this instance: Premise: A man with a black helmet on smokes a cigarette while he drives his motorcycle in traffic.
Hypothesis: A man smoking and riding a motorcycle while weaving through dense city traffic.
Update: The man is dangerously weaving through traffic and causing other drivers to be frustrated.
