Final answer:
Without specific context, the number of times Arthur must request Bedivere to comply cannot be accurately determined; it depends on the version of the Arthurian legend being referenced.
Step-by-step explanation:
The question refers to a scenario involving characters Arthur and Bedivere, likely from Arthurian legends or related literature. However, without the specific context or text in which this request takes place, it is not possible to accurately determine how many times Arthur must ask Bedivere before compliance is given. Typically, in tales of King Arthur, Sir Bedivere is known for hesitating to throw Excalibur into the lake at Arthur's request, doing so only after being asked three times. Yet this scenario could vary depending on the adaptation or retelling of the story.
