Question

as the king became more and more infirm, his ability to make wise decisions weakened and he was no longer able to lead effectively. infirm means...
very helpful or useful
not requiring much work
not in good health; not well
agreeing with; supporting

Explanation:

To determine the meaning of "infirm", we analyze the context: the king's decision - making ability weakened and he couldn't lead effectively as he became more infirm. Now we check each option:

• "very helpful or useful" has no relation to the context of the king's declining leadership ability due to his condition.
• "not requiring much work" is also irrelevant to the situation described.
• "not in good health; not well" fits the context because a decline in health (being infirm) would logically lead to a weakening of decision - making and leadership ability.
• "agreeing with; supporting" has nothing to do with the context.

Answer:

C. not in good health; not well (assuming the options are labeled A, B, C, D with A being "very helpful or useful", B being "not requiring much work", C being "not in good health; not well", D being "agreeing with; supporting")
