Debra wrote the following paragraphs for an article about seatbelts on airplanes. Read the paragraphs and look for corrections Debra needs to make. Then answer the questions that follow.
(1) Like cars, airplanes also have seatbelts that passengers must wear at certain times during the flight. (2) While a car seat belt is a shoulder harness with a lap belt, an airplane seatbelt is only a lap belt. (3) Some may question if wearing only a lap seatbelt is enough for the safety of the passengers.
(4) Experts consider certain factors in deciding in favor of lap seatbelts in airplanes. (5) The priority is the safety of passengers. (6) In case commercial airlines have an excellent safety record, a shoulder seatbelt is not necessary for airplanes. (7) Another consideration is the comfort of the passengers. (8) The experts think a shoulder seatbelt will probably be uncomfortable on longer flights. (9) The third factor is the considerable cost of installing shoulder seatbelts on airplanes. (10) Thus, all three factors, considered together make an overwhelming case for lap seatbelts.
