Which research question would be the most effective in researching the effects of text messaging on adolescents?

The question asks about the effects of text messaging on adolescents, so the strongest research question should examine a possible change or impact. “Does text messaging affect adolescents’ ability to read and write?” directly investigates an effect. The other choices ask how often adolescents text, how many use it, or which communication method they prefer; those measure use or preferences rather than effects.
