And I'll throw my hat in the ring too, albeit briefly
I talk all the time about the idea of seeking to eliminate answers rather than select one, and that's particularly crucial on the harder questions (those later in an LR section). The reason why is that the test makers are masterful at disguising right answers in a way that makes their "right-ness" less obvious and difficult to spot. But if you approach the choices from the perspective of finding four wrong answers—essentially comparing the options in terms of which is worse, instead of which is better—then you can worry less about the single option that's correct but hidden, and more about the issues that plague the four incorrect choices and allow them to be dismissed.
I work through LR with a kind of focused malice towards to answers, literally hating each choice and trying to find a reason to justify that hate, and only letting options linger as contenders when answers have changed my mind and persuaded me to tolerate them. What happens as a result is that I tend to work through the harder questions by process of elimination, instead of optimistically trying to make answers work. The odds that (A) (or any other) is correct are tiny, just 20%, so why expect it to work out? Treat it as wrong until it forces you to reconsider.
The same holds true as you narrow it down to two: stop trying to decide which is "better," and instead determine which is worse. If you had to get rid of one, which would it be? That subtle shift in how you compare choices can make a world of difference, and I think you'll find it dramatically improves your accuracy in the situation you've described!
I hope that helps!
