It's factual analysis.Please solve it for me

Scenario: Al bought a case of beer because his friends were coming over to watch the Grey Cup football game. During the game, Al opened a beer, poured about a third of it into Bob's glass, and handed the can to Chuck. Bob noticed the strange orange colour of the beer and called everyone's attention to it; unfortunately, Chuck had drunk most of the beer from the can before he heard Bob. There had been a small battery in the can that contaminated the beer. Chuck was seriously injured.
