Passage (Teens and Technology Addiction)
In the past five years, parents have watched with horror as teenagers have become permanently attached to their ipods, cellphones, and laptops. A teenager today spends up to three times as long staring at a screen (television or computer) than teenagers ten years ago. In an effort to remind teenagers that technology is not essential to life, some parents are rationing out screen time for the week. Other parents don't allow their children to watch any television during the school week. Some families are even taking week-long camping trips in which no technology is allowed at all--even a cell phone. The struggle to break technology dependency is constant.

Which of the following would be the strongest piece of supporting evidence for the claim in this passage?

A. Teenagers in America are generally lazier than youth in other countries, such as Japan.

B. It is my opinion that teenagers should spend more time outside instead of staring at a screen.

C. According to The American Journal of Medicine, “the rise in obesity rates among children and teens directly correlates to the rise in popularity of smartphones in America”.

D. Obesity is a huge problem in America, and teen addiction to technology is the main cause of this modern epidemic.
