Like most things, not one book that covers the whole range. The questions bring together a whole range of things such as underpinning electrical theory, typical operating parameters, real world limitations, possible non-ideal conditions that lead to some sort of failure and different TC types which is why there is such a range of different variabilities in the questions which, on first reading, appear to be asking essentially the same thing.
Sorry, that is not the answer you were looking for, but the exam is supposed to be challenging!
