Final answer:
The true evidence that Egaeus has maimed Berenice is the bloody clothing he's wearing. Other mentioned details are not evidences.
Step-by-step explanation:
The evidence that Egaeus has maimed Berenice includes all of these EXCEPT:
- The fingernail indentations on his arms from when she must have struggled: False
- The bloody clothing he is wearing when the servant enters the room: True
- The spade leaning on the wall where it must have been parked after digging her up: False
- The severed finger in his pocket that he took from her with his surgical tools: False
Only one of the statements given is true, specifically the statement about the bloody clothing. The other statements about fingernail indentations, the spade, and the severed finger in his pocket do not serve as evidence that Egaeus maimed Berenice.
