B. we could see if the computing solution is necessary
C. we could see if the computing solution would make life easier for residents of that country
D. we could see if the computing solution works well withing that country's existing system
WHICH OF THE ABOVE??

A, C, and D.

A. Determining if there is a desire for the computing solution in that country would indicate its potential efficiency as it shows a level of interest and demand from the target users.

C. Assessing if the computing solution would make life easier for residents of that country would also indicate its efficiency as it demonstrates the potential benefits and positive impact it could have on the users.

D. Checking if the computing solution works well within that country's existing system is important in evaluating its efficiency as compatibility and integration with existing infrastructure can play a significant role in its effectiveness.
