The scent associated with vomit is often very unpleasant and not fresh at all due to stomach acids and a chemical called bile which comes up along with undigested food and hence no human being would want to breathe that in.
Context: "I was getting in a Taxi and noticed someone had thrown up in the backseat."
Hypothesis: I saw vomit in the backseat of the Taxi and it really gave me an appetite.
Based on the context, is the hypothesis true, false, or unknown?
