The question uses the word "during" insertion sort, "further" comparisons and then the solution doesn't consider them!! :/
Also it is not clear as up to which element comparison has been done. I mean if the initial array was like {75,25,95,125,80,5,10} then 1st iteration will take key as 25 and make the array like {25,75,95,125,80,5,10} (i.e. the one given in the question). If this is the case then we have to start solving by taking key=95.
Though at first I also assumed key to be 80.
To me it is not a well framed question :/
