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.

Premise: A young girl is in a teal colored netted skirt and wearing a shirt with a peace sign.
Hypothesis: A young girl is in a teal colored netted skirt and wearing a shirt with a peace sign and a red cap.
Update: All of the girl's hair can be seen.
weakener
The update is a weakener because if all of the girl's hair is seen, she cannot be wearing a cap, which would make it less likely that the hypothesis is true..
