I want to test my hypothesis about the reading of the word.

Choose USA if you are from USA.

Choose OTHER if you are from any other part of the world.

Choose Equal, if in your reading "given" same as "conditioned upon". The event might happen or might not happen.

Choose Not Equal, if in your reading "given" is not the same as "conditioned upon". "Given" is part of the setting and tells us about a known fact.
