Which person has the best qualifications to write a credible article about the history of food production in the United States?
A. A television reporter who visited the fast-food museum in
Chicago, Illinois
B. A professor of history who has published books about the food
production industry
O C. A Senator whose proposed law would overhaul the food
production industry
D. A former worker in the meat-packing industry who is angry about
being fired

I think its B

Explanation:

since a professor has already written books on the production of food he should be well prepared for writing an article. People who already write have a better ability to grab a reader's attention.

the tv reporter has only visited a single fast food museum, so he wouldn't have much to write on.

the former worker is already mad at being fired (he would write negatively about the place) and only has knowledge about meat. (in my opinion)

the senator could be a good option but his field is law not writing.

hope this helps :-)

i pretty sure it is old

explanation:

the answer to "what does the narrator realize by the end of the story" is b.
