Using a new technique will almost always slow you down at first, until you get used to using it

I think it would be better to describe it as "the individuals', between those nations, access being spoken about." I'm not sure of advice on how to change how you interpret things, but a better comparison would be "if your friend spends more time golfing than you do, could it be because the Top Golf in their city is open more often than the Top Golf in your city?"

The author calls them examples in the passage. They are specific examples of how and where the assertions made go against fact.

If you haven't done the Logic of Causation section of the fundamentals, I'd recommend it

Oftentimes, the perspective of researchers is presented as the results of their research. That's basically it, the perspective of the researchers IS the research and what that research proves/disproves.

I don't think so, Simpson's argument isn't about what the purpose of a museum should be, instead he's talking about the kind of works a museum should collect.

Some of the harder questions on the LSAT can trick you with word choice and have two answers that both look correct except one has a single word that changes the meaning of the entire thing. I've found it can be helpful to just glance through the other choices just in case you see another that could be correct on first glance.

While either does often mean "only," he's referring specifically to the methods you will want to use to get the right answer. It remains true that "if you get the correct answer, you recognized the right answer OR you eliminated the four wrong answers OR you just guessed."

Since the first two methods are the only way to guarantee you are correct, they are not the only ways to be correct.

Another way to say it is "If you got the question wrong, it is always true that you did not 1. recognize the right answer AND 2. you did not eliminate the four wrong answers." In this scenario, it may still be true that you guessed.

Recognizing the right answer is sufficient to get the question right

Recog→Correct

Eliminating the four wrong answers is sufficient to get the question right.

Elim4→Correct

Recog OR Elim4→Correct

Recog AND Elim4→Correct

Recog and /Elim4→Correct

/Recog and Elim4→Correct

Guessing is unreliable in getting the answer correct, but sometimes it works.

Guess←s→Correct

Guess←s→/Correct

Guess ←s→ Correct or /Correct

Guessing is not always correct. An answer gained by either recognizing the right answer or eliminating all 4 wrong answers is always correct.

Few necessitates more than 1 and less than half. Negating most includes 0, 1, and half.
