Editorial: Last year, many polls found that most people in our country claimed to be tired of television news programs' obsession with celebrity scandals and to be unwilling to watch such programs.
Conclusion (This indicates that)
When responding to polls, whether they know it or not, people often portray themselves as they wish to be perceived, not how they actually are.
Evidence
Last year, in polls, people would say that they were sick of tabloid TV shows, but the ratings of those shows were still super high.
Evaluate
The author is interpreting the meaning behind a study/poll, so we could use an Explain Curious Fact mindset.
Curious Fact … How can it be that tabloid TV has soaring ratings, given that polls say people don’t like tabloid TV and are unwilling to watch it?
Author’s Explanation … It’s because people responded to those polls the way they want to be seen, not the way they really are. They want to be seen as someone who is above watching trashy tabloid TV. But in reality these people go home and watch the tabloid shows.
Goal
Since this is Necessary Assumption, the correct answer could Rule Out an alternate explanation for why there’s a gap between the poll and the tv ratings.
Or it could spell out something required for the author’s explanation to be plausible.
