As discussed in the original explanation in this thread, S2KMo, the flaw in the argument is not about a connection between socialized medicine and technological achievement, but between lower infant mortality and technological achievement. Answer B fails to address that problematic gap, but focuses instead on a gap that isn't really a problem.
In addition, as you noted, answer B is playing a bit of a shell game by swapping out the term "socialism" for the term "socialized medicine", which was what the argument was about. There doesn't need to be any connection between the economic system of socialism and technological achievement, so saying that the argument doesn't establish one isn't a flaw of the argument!
#4 - It is more desirable to have some form of socialized
Hello the reason I avoided answer A was because it felt like a restatement of the stimulus how do I avoid making a similar mistake in the future.
This is a good question There is, unfortunately, no simple answer though! The first step is to realize that they will indeed play games that are based on small word and meaning changes within answer choices. This is one of the true difficulties of the LSAT, and something that you have to be on-guard for. Second, you will get better over time at recognizing what they are doing. Battling the LSAT is a learning process, but one of the benefits is that you will begin to recognize the types of answers they use as well as the language. Now that you know you have to be prepared for small changes in meaning while they use similar language, next time you will be better situated to recognize what is happening. Forewarned is forearmed! Last, just as a point for this particular problem, in a Weaken question they are extremely unlikely to simply restate an part of the stimulus as a complete answer. There's be no reason for them to do it, and it would be too easy to eliminate. So, in a future Weaken question if you see what appears to be a direct restatement to you, just read it again to make sure
Please let me know if that helps. Thanks!
