Answer:
The answer is B. "Television is a bad influence on children."
Explanation:
The excerpt mainly focuses on the general idea that television has a bad influence on children, so I would say the best answer choice is "television has a bad influence on children."
This excerpt doesn't really specify three types of show, nor does it discuss any of the "good" elements or benefits of children's television viewing, it does discuss explicit content, but not in the sense that it provides entertainment for all ages.
