Final answer:
The speaker citing the study is likely using both emotional appeal regarding children's health and logical appeal via scientific evidence to address the effects of screen time.
Step-by-step explanation:
By referencing the study in England that found children who spent more than two hours a day in front of screens had greater psychological difficulties, the speaker is most likely both emotionally appealing to the reader by pointing out the serious effects of screen time on children and logically appealing to the reader by presenting the findings of a clinical study. Option A suggests that the statement is meant to elicit emotional concern about the welfare of children by detailing the negative consequences of excessive screen time. Option B, however, speaks to a logical appeal made by citing a study, giving the claim a basis in research and scientific evidence as opposed to merely an emotional or anecdotal assertion.
