Vomit is an incredibly nauseating sight and often times seeing someone else vomit can cause the onlooker to vomit as well
Context: "I was getting in a Taxi and noticed someone had thrown up in the backseat." Claim: "I  saw vomit in the backseat of the Taxi and it made me want to vomit too."
Considering the context, is the claim true, false, or unknown?
