I'm also applying for the 2027 cycle and graduated basically in 2023. Feels weird and late but I wanted to work first and save up. My friends already in law school have plenty of older classmates which makes me feel better. Never too late.

The reason I got confused about B was because the 'varies significantly' I did not think HAD to mean some areas had very very little water. Maybe the significant variations could be a little short on water to having way too much water available and no chance of shortage in the near future. I understand why the others are wrong, but that's why B tripped me up.

If part of the iron hypothesis was asking "how can a sun composed largely or iron generate the huge energy output of the sun?" And Payne realized the hypothesis answer needed to be re-examined - she was rejecting the iron hypothesis in part because it could not account for the energy produced by the sun. Nuclear fusion is the answer - which Payne did not know at the time, but she had rejected the hypothesis and doesn't the discussion of nuclear fusion serve to clarify a reason for rejecting the iron hypothesis? Her data (even if she did not know it) did have a way of producing the sun's energy output.

In the star question brown dwarfs are identified by their mass and whether or not lithium is present in their atmospheres. A brown dwarf’s lithium cannot be consumed because they do not have a functional nuclear furnace. If it says they are identified by whether or not they have lithium, does that really mean all brown dwarfs have lithium? Couldn't they not have lithium in their atmosphere and still be classified as a type of brown dwarf? And then the last sentence would mean if a brown dwarf does have lithium, then it cannot be consumed. But it doesn't have to mean that a brown dwarf has lithium, does it?

For C - isn't there an absence of evidence that the constituents oppose the bill to reduce corporate income tax, and there is the existence of evidence that they do not want high taxes, and the argument is confusing 'they do not want high taxes' for 'they support lowering the corporate income tax.' still having a hard time understanding how C is wrong
