@OliviaPare I also had the same analysis as you! It doesn't make sense to me that it is comparing which is more sophisticated, because that is already a stated fact--the currently available instruments are less sophisticated (otherwise more sophisticated instruments wouldn't even be possible). I would love an instructor to weigh in on our thoughts!

This is how I responded to number 3, which makes the most sense to me, but it is not the same as the answer: 

1. retaliatory force equal or less than any other nation vs retaliatory force greater than any other nation

2. which allows for maintaining maximum deterrence from aggression

3. have a retaliatory force greater than any other nation
