Not sure if this will help anyone, but the way I like to think of these is as a "battle", and you have to determine "the competition", or who you are fighting against. For example in Q3:

• It is our nation vs the other nations - therefore you have to find the subject and what it is being tested against. Here, our nation would be tested against others. Well, how will the nation do that?

• Simply; with a retaliatory force greater than other nations.

Not sure if this makes sense to others but I applied it to all the questions here, but the analogy works better when you talk about war and nation-states. Lol

@Jurcis I never expected to see a Drake Maye reference studying for my LSAT. This just confirmed I will score a 180 now. Thanks!
