Read the excerpt: "Teenage caffeine consumption, once limited to sodas and hot chocolate, now has nearly become the norm in the Bay Area and nationally. Though no statistics exist to chart teenage coffee drinkers--the National Coffee Association polls only consumers 18 and older-a drive past any coffeehouse near a high school would show that it's replaced the iconic malt shop of the 50s or 7-Eleven of the 70s as a place to socialize." What is the central idea of the above excerpt?
O Teens no longer hang out at malt shops or 7 Elevens to socialize.
O Teens are drinking more caffeine now than during the 50s to the 70s
O Teens don't realize the amount of hidden caffeine they are consuming. O Teens today are becoming more addicted to coffee both nationally and in the Bay area.
