Final answer:
Skyrris Bolgolam was "well-versed in affairs," which means he was knowledgeable. The term 'well-versed' implies proficiency and familiarity with a subject. In the context of war, lacking versed knowledge can lead to ineffective planning, unlike a wise leader who blends various considerations. The correct answer is 1) knowledgeable.
Step-by-step explanation:
The phrase "well-versed in affairs" from the text indicates that Skyrris Bolgolam was knowledgeable in his field. This means he had considerable understanding and was experienced in the matters he dealt with. When someone is described as 'well-versed,' it typically suggests they are proficient and very familiar with a particular subject area or task.
For instance, in military terms, a student of war who is not sufficiently versed in the art of war, despite knowing the Five Advantages, might not be skilled in adapting their plans and could thereby fail to manage their personnel effectively. Conversely, a wise leader blends considerations of advantage and disadvantage in their planning, showcasing their depth of knowledge and strategic thinking.
Moreover, the text mentions that being acquainted with the 'Five Advantages' is not enough for a student of war who lacks the ability to vary his plans. This further emphasizes Bolgolam's knowledge of the subject and his ability to adapt and strategize effectively.
Therefore, based on the given information, the correct answer is: 1) knowledgeable.
