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 are drinking more caffeine now than during the 50s to the 70s
Teens today are becoming more addicted to coffee both nationally and in the Bay
area.
Teens don't realize the amount of hidden caffeine they are consuming.
Teens no longer hang out at malt shops or 7 Elevens to socialize.
