i don't believe that for those of us that had the argument being "some cultivars" v "most cultivars" is 'wrong'. i think the most important part of these exercises is to understand WHY it would be "sorghum v most other cultivars", and to be able to have a reasoning for that logic. as long as you understand the baseline objects being compared (some cultivars v others, sorghum v others), then the conclusion for the most part is the same; we all agree that (some cultivars or sorghum) is closer related morphologically than most other cultivars.
