The stimulus leads with its conclusion: educational television is a contradiction in terms — i.e., television can't be educational. Three premises are provided, each contrasting "the classroom" or "school" with television. First, the classroom encourages social interaction, while television encourages solitude; second, school focuses on language, while television focuses on images; third, in the classroom, fun is a means to an end, while on television fun is an end in itself.
From the premise-conclusion structure, you might be tempted to point out that the argument assumes that something that encourages solitude, focuses on images, and treats fun as an end in itself — i.e., that has all three characteristics that television has — cannot be educational. You would be right, but that would be a sufficient assumption. There's another noticeable jump in this argument that helps us identify a necessary assumption. Notice that all the premises talk about "the classroom" or "school," and the conclusion is about education in general. This suggests that a necessary assumption here is that if something does not look like school or the classroom in at least these three respects, it does not count as education — i.e., education must look like the classroom in at least these three respects.
