While doing Text completion question, I am not able to figure out what is the hint/clue to fill up the blank. Not the support/contrast concept but how the word ‘by decade’ from the below question is used to fill the blank.
I am referring to the first blank. ‘by decades’ is the clue used to fill the first blank.
However, I am not asking about this particular question. I am asking about strategy to identify hints. Like greg used ‘by decades’ to suggest that the first blank would be a term like chronic or prolonged.
