Questions 9-18

·Read the following passage and answer questions 9-18.
1. When one of your car tires goes flat, there are two things you can do. Groan and change or, if you don’t have a spare, stand helplessly behind the road and hope someone to your rescue. Now comes a third alternative, called Quickwheel. It is designed to get disabled motorists rolling again as quickly as possible.
2. Quickwheel is essentially a tiny trailer — complete with three tough little wheels of it’s own — that support the flat tire and enable the motorist to drive to the service station without losing much time or expending much energy. The product is manufactured in the Netherlands but is owned and marketed by a US company. Quickwheel inc. of Greenwich, Connecticut. According to the firm’s president, Robert Bockweg, the product meets each of the major concerns that consumers associate with flat tires: safety lost time and physical exertion.
3. To use it, motorists simply unfold the product to its fully extended position, set it in front of the disabled tire, drive the car on to the Quickwheel’s ramp and attach a special safety strap over the tire. The tire is then locked, or cradled, in Quickwheel’s metal frame. The device’s three wheels do the rest of work.
4. According to Quckwheel Inc., its product can be driven "four miles" at speeds of up to 45 miles per hour without any noticeable change in the vehicle’s breaking or steer operation. The company also claims that it can be used on just any type of car, jeep, mini-van or trailer.
5. Bockweg says that Quickwheel will be sold in the US, at a price of $150. Distribution agreements now being negotiated should make the product available in Japan, Canada and West Europe in the future.
