Anytime you have a chance, study the next set of questions. Make assumptions about what you think you will hear.When you make assumptions, ask yourself: Who? What? When ? Wh&re? and How? | READING SKILLS 61 D Part of the reason there are so many inconsistencies related to colorblindness or color vision deficiency as it is called in the medical world is that it is difficult to know exactly which colors each human can see.

Those with normal vision can distinguish the number from the background while those with color vision deficiency will only see the dots.

For example there is a longstanding belief that colorblindness can aid military soldiers because it gives them the ability to see through camouflage. Another belief is that everyone becomes colorblind in an emergency situation.
