Explanation:
The responsibility of driving is a lot for younger drivers because they don't have experience. Younger drivers get distracted the most. Kids under 18 want to impress their friends and in an attempt to do so may crash. Phones are very popular with children under 18 and they are more likely to use it while driving. To top it off, kids under 18 like to drive fast and don't have the reaction time of adults.
Based on my information, I believe that the higher authorities that would choose the prime ministers would actually be the "house of commons". Going back a few years, many of the "house of commons" actually did not have the responsibility in order to do this, but then, the government figured that it would be better if they were to handle on this responsibility.
chronology is the right one
