The correct answer is A. The authorities in Pocagal have not done everything within their control to affect change.

Explanation:

The reasoning in the passage suggests that Pocagal's authorities need to develop a new approach because their current efforts to deal with SBA-LN are ineffective in preventing the natural course of life. This implies that they haven't exhausted all possible avenues for change.

Why other options are incorrect:

B. It's of vital interest to Pocagal that SBA-LN be disbanded:
While the passage implies that Pocagal wants to address the situation with SBA-LN, it doesn't explicitly state that disbanding it is a vital interest. The passage focuses on the impact on the children and the need for a new approach, which could involve various strategies.

C. The blockade, and the threats of renewed hostilities are among the many other threats faced by Pocagal:
The passage mentions the blockade and threats of renewed hostilities as ongoing challenges, but it doesn't imply that they are just one of many threats. The focus is on these specific issues in relation to SBA-LN.

D. The Pocagal military is ineffective:
The passage doesn't state that the military is ineffective, but rather that their attempts to destroy SBA-LN (and the resulting blockade) haven't prevented life from going on. The argument is about the approach, not the military's effectiveness in general.

E. A nation's resources are best spent if it is known that the maximum amount of improvement to the general good can be attained:
This statement is a general principle, but it's not directly related to the reasoning in the passage. The passage focuses on the need for a new approach, not a discussion of optimal resource allocation.
