Sample: the first question, solved
A circle graph shows a slice labeled 10%. What can you conclude about that category?
And one from the hard end
Design the strongest possible critique of a circle graph that has: no source note, an inconsistent number of significant figures across slices (one at 33%, another at 12.5%), a 3D tilt effect, and slice percentages summing to 97%. Rank which flaw is most serious for trustworthiness, and justify the ranking.
