I just received a peer critique on a short paper I wrote on the U.S. school lunch system. The first paragraph starts: "Chef Jamie Oliver is hard at work on a chicken carcass, cleanly dividing it into thirds...". (It goes on to detail that part of Food Revolution where he demonstrates how chicken nuggets are made--the chopped carcass is put in a processor, etc.) The author of the critique marked this part of the sentence in red: "what are thirds?--a serving?".
...Should I bother to read the rest of this critique?
