On those survey results several items show a 5 item bar chart with the bars labeled 1, 2, 3, 4, 5 showing the counts and percentages of respondents who chose 1, 2, 3, 4, or 5.

For example, "Do you prefer modern or older architecture?" shows 20% chose 1, 34.6% chose 2, 25.6% chose 3, 15% chose 4, and 4.8% chose 5.

WTF does this mean? I don'e see anything that says what those labels mean. I'd guess for questions asking X or Y they mean X, lean X, no preference, lean Y, and Y but in what order?

But some aren't comparisons. One such chart is simply titled "Global Warming". What does it mean to answer "2" to that?
