Read the following passage and choose the correct answer to each of the questions.

Americans, in general, are big eaters and one of the greatest pleasures of the day is sitting down to a hearty breakfast. Most neighborhood dinners cafeterias offer breakfast specials. Some can be as simple as buttered toast with coffee. Others can almost be equivalent to a full course meal which can provide enough calories for the entire day. The breakfast special is offered daily and runs usually from seven until eleven in the morning after which the prices change and everything is ordered a la carte.

Some fast food restaurants offer an "all-you-can-eat" buffet breakfast which may include more than thirty choices of every breakfast item imaginable. For a set price one can get as many refills as one wants. A complete breakfast will cost less than five dollars with tips included.

Some regional favorites also add variety to the American breakfast. In the south, grits with butter may replace hash brown, and hot spicy biscuits and gravy seasoned with bits of meat make up a meal in themselves. Fortified with a hearty breakfast, Americans find it easier to face the challenges of another day.
