Well, look at what the questions are asking. I don't remember the exact wording, but...
The 1st set of questions asks if the word relates to the internal or external. (I or E)
The 2nd set asks if the word is understood better by observation or intuition. (S or N)
The 3rd set asks if the words have a subject or objective meaning to you. (F or T)
The 4th sets asks if you have a definite or indefinite understanding of the words. (J or P)
Or something like that.
