Raise the driving age to eighteen! after reading mr. j. brown's letter, dated august 15, i feel compelled to write and let your readers know how i feel about raising the driving age from 16 to 18. teenagers should not be allowed to drive until they are 18. only high school graduates should be given a driver's license, and only after successfully completing a driver's education class during high school. right now, 15 year-olds can get a practice permit and try for their license at 16. eighteen is a better age. at 18, people are more mature and better able to make mature decisions. not all 18 year-olds are mature, but the majority of them are. at least we are more mature than 15 year-olds. what is the main purpose of this passage? a) to warn older drivers to be careful when they drive b) to convince readers to support raising the driving age c) to entertain teens with stories of safe drivers d) to support insurance claims against teens who get into accidents
