Keeping in view the human psychology and the trend from the past papers, let us have an introspection into the examiner;s mind as to where he does and will choose the pair of words from.
The main focus whenever one opens a book is in the very beginning portion and then the secondary look is right at the end followed by a glance over somewhere in the middle.
Therefore, almost 80 % of Pair Of Words mostly given in the papers are from either starting alphabets or the ending ones.
Here is my guess and keen observation as to where he mostly takes the Pair Of Words from.
The alphabets have mostly been,
A, C, D, E, I, M, P, S, V and W.
One may argue.
