Can the negation technique applied to every assumption question? Also can we eliminate options if negation technique doesn't fit the bill
Yes, the negation technique will always give you the right answer. The GMAT says that an assumption is always something that's critically necessary to an argument - think about an assumption as the engine of a car. If you remove the engine (by negating the assumption), there's no possible way to drive the car to its destination.
On the other hand, if you negate an answer choice and there's still some possible way for the argument to draw its conclusion logically, then it wasn't really an assumption.
That's part of the definition of what an assumption is, so there's no way for it to not work. That said, sometimes it's hard to apply the negation test. Sometimes it isn't obvious how to negate an answer choice, especially one that already has one or more negative words in it. And sometimes it takes a lot of time to apply it. Generally, I'd recommend getting down to 2-3 answer choices before using it, rather than using it on every answer choice from the start.
