Question

review the sixth paragraph.
wanted to, you could eat a burrito while playing cards, too. so, burritos fulfill the same purpose as the legendary first sandwich eaten by the earl of sandwich.
arguing about the definition of a sandwich may sound silly, but it can have serious consequences. for example, sandwiches are sometimes taxed differently than non - sandwich breads, like plain unsliced bagels. also, some shopping areas only allow one sandwich restaurant to be built on their property. that means that a restaurant may or may not be allowed to open in a particular location depending on how \sandwich\ is defined. therefore, its important for everyone to agree on one definition for a sandwich. and lets be fair: a burrito is definitely a sandwich.
what does the sixth paragraph do?
it suggests a new definition for sandwich.
it provides evidence for why a burrito is a sandwich.
