The first question is unbiased the second is biased. The biased question tries to get you to answer a certain way. Heres a more extreme example:
"Do you drive to work or bike"

vs

"Do you destroy the environment by driving a car or do you care about our planet and bike?" Nobody wants to say they destroy the planet so they will be more inclined to say they bike, regardless of if they do or not.

An answer for the second question would be "What do you think effects the weight of teenage girls" or "What effect does TV have on teenage girls?"



Also as a side note my stats book was obsessed with girl's and their weight and it was really creepy, seems like yours is too lol

ok, this one actually helped, thanks pal lol
