Which research question would be most appropriate for a four to five-page research paper? does taco bell or garcia's make a better cheese quesadilla? does taco bell or garcia's offer a more nutritional menu? which taco bell location has the best service? how many customers visited garcia's last year?

I would have to say the question that would be most appropriate for a four to five-page research paper would be on the question, "Does Taco Bell or Garcia's offer a more nutritional menu". The reason for my answer is you can go into detail about what they both offer in a nutritional menu, long with which is better and why. To me this just seem like the question you could write more about. I really hope that helped you out some.
