Ihave to write a research paragraph about vinegar which word should i start with?

A long long time, in a galaxy far away, when I was in high school, I always enjoyed writing once I was doing it, but getting started was always a problem for me.  Then one day, I happened to stumble over a suggestion for writers that fixed everything up for me, and I never had that problem again.  The suggestion is so simple, brilliant, and effective, I would never try to tell you that I invented it.  I'm just thankful that I happened to see it:

Step #1: At that time, it was "Put a blank sheet of paper in your typewriter."  Now I guess it would be "Boot up, log on, open your word-processor, start a new file, and close ALL other apps."

Step #2: At the top, write the word " The ".  Now you're running !

the answer is   b suffix addition
