Final answer:
There is no provided evidence of Chas being intoxicated when he fell from the tower based on the given excerpts. Multiple scenarios are depicted, but none directly tie Chas to having consumed alcohol before his fall.
Step-by-step explanation:
Based on the provided references, there is no specific evidence that Chas had been consuming alcohol when he fell from the tower. The excerpts detail various instances of characters in different situations, including a man who had a hand wound (bleeding but not necessarily ), a parachutist who lost consciousness while descending (no mention of intoxication), and a situation where a character drinks whiskey and water after rowing (which is separate and does not indicate intoxication at the time of an accident). The clearest indication of intoxication is mentioned in the excerpt related to Fortunato, whose inebriation had 'in a great measure worn off' after being trapped, suggesting that he was intoxicated earlier. However, these references do not directly relate to Chas. Without additional context directly relating to Chas's state before the fall, we lack evidence of alcohol consumption affecting the incident in question.
