A note on methodology: typically in experimental surveys you don’t want to prime your subjects with words or phrasing that could lead to positive or negative bias. Additionally, negatively-biased phrasing on a public survey could also attract mostly those with negative views. This would skew your sample even further than solely priming. With that said, I have no idea what any of those icons are.
I think the whole quiz is a joke, to prove a point.
I also think the quiz is to prove a point. Those icons are not helpful at all. The opposite of the MS Office icons which are so recognizable all other office suites copied the color scheme.
