When they list a series of numbers and give you choices about which list of numbers complete the series then all answers can be justified in the lack of proper context
They do not provide any context as to which completion is better than the other
However if someone is familiar with the thinking pattern of the test writer or memorised the study guides one can get the correct answer not through being a better mathematician or scientist but through understanding social norms
