## Why these answers are right

**14. C.** Section C notes that the average car spends more than 90 percent of its life parked. A parked car is a car not being used, and the percentage is a reference to an amount of time, so this information belongs to section C.

**15. B.** Section B lists a series of benefits for the people inside the car: fewer collisions, time freed up to work, socialise or relax, and more independence for older or disabled travellers. Several benefits aimed at individual travellers point to section B.

**16. E.** Section E says that people buying access to a range of vehicles will have the freedom to select one that best suits their needs for a particular journey. Selecting a suitable car for a journey paraphrases choosing the most appropriate vehicle for each trip, so the answer is E.
