What is logic to find answer here?
For blank (i), it seems pretty clear that it’s something positive. Look for how the sentence backs this - makes her a landmark. From this, you can proceed to eliminate B & C. Detachment from? That doesn’t match the evidence in the sentence. Curiosity about? Still doesn’t fit the evidence - the rest of the text doesn’t mention curiosity. Hence, Blank (i) is A.
.
As for blank (ii) - it seems tricky to me since my vocabulary isn’t complete. Not being able to figure it out just goes to show that vocabulary is an important part of prep, and we need to have a foundation in it. Sure, there’s the logic that the word in blank (ii) should mean something along the lines of the phrase “agonizing over how far to try to represent the minute details of performance” - but you can’t move forward unless you have that vocab foundation to select the right one or eliminate the wrong ones (as we did for blank (i)).
